Joan Beauregard

Joan is the middle child of five siblings born over the span of twenty-three years— a station in the family that has positioned her as a bridge between two generations. From an early age, Joan learned to listen, appreciate differences of opinion, negotiate, and bring people together for the greater good.
When Joan was in third grade she began skipping recess to stay in and help wipe down the blackboards. She loved being around her teachers so much that she would soak up just about everything they did—from correcting papers to preparing lessons.  When she was ten, her father installed a large slate black board on their back porch so she could ‘teach’ her two young siblings and their stuffed animals. In high school she was awarded a “Future Teacher’s Scholarship”  and she and her younger sister both went on to become educators.
Loyal, focused, insightful, and trustworthy, Joan is masterful at seeing through the lens of possibility and helping individuals and teams connect to their own potential. As a partner, she’s motivated by the ripple effect: she knows that when the right leader is in place, the community can be its best, and the quality of the education increases. In turn, students leave a school prepared to go out into the world and make it better.

Tracy Bennett

Spending summers sailing on Lake Michigan, Tracy learned from her father how to chart a course using the practical parallel rule as well as an instinctive understanding of weather patterns. This approach – utilizing data and facts while paying attention to intuition and changing circumstances – continues to serve her well. High energy and happiest when outdoors, Tracy has run marathons, hiked around Mont Blanc, and walked across Spain on the Camino Santiago. She’s thrilled to have recently returned to New England (close to her alma mater, Dartmouth), with easy access to the Green and White Mountains.
Tracy brings a comprehensive understanding of schools to her work. A parent of five independent school graduates, Tracy has 15 years of experience as a trustee, including serving as board chair. She began her professional journey teaching at a New Hampshire boarding school, and then shifted into senior leadership roles in enrollment management, communications, and fundraising after moving to Seattle. As a head of school for the past decade, Tracy loved the variety each day offered – joining kindergartners for morning circle to a meeting with a major donor to a facility construction tour – each uniquely rewarding.
Tracy’s Master’s thesis explored how women lead schools and what supports their success. She learned two things are most important: getting the opportunity and having a role model and mentor. Known for her compassion, keen listening, and astute observations, Tracy continues to find joy in supporting rising female school leaders and is grateful to those women who have done the same for her.

Pilar Cabeza de Vaca

One of the few Latina heads of school in Europe and in the United States, Pilar didn’t start out wanting to teach—she wanted to go into something more “international.” But aside from working as a secretary, teaching was the only job available to women in Ecuador.
PIlar’s career began in earnest at her alma mater, the American School of Quito, where she wanted to give back what she had received. Discovering a magic chemistry between her and her students, she came to thoroughly enjoy each day in the classroom. Her passion was palpable: two years later she was promoted into administration and after four years, she was appointed Head of School.
As an administrator, Pilar developed into a powerful mentor. She believes there is nothing more rewarding than being a part of someone else’s success and lights up to see others achieve—particularly those things they have deemed impossible. With a career spanning three continents in over forty years, Pilar is masterful at putting herself in other people’s shoes. Fluent in English, Spanish, and French (and with reading knowledge of Russian),  her authenticity and self-effacing humor come across in a number of languages.

Her students call her generous, her colleagues call her a “change agent” and interviewees say there is something about her that puts them at ease.

Nat Conard

Nat grew up in Vermont on the campus of The Mountain School, a small boarding school which his parents founded in the early sixties. As long as he can remember, he worked the school farm surrounded by conversations about leadership and organizational change. He became fascinated with effectiveness: What makes some people really strong leaders while others, whose ideas might be just as good, struggle to get anything accomplished?
Nat found his first post-college job in a classified ad and began teaching in the New Hampshire public schools. Making barely enough to live on, he eventually decided to go to business school. Though he was not naive to what an MBA entailed, his first course in organizational behavior left him mind blown—not only could leadership be studied and developed, but the research confirmed what he had already observed: effective leadership begins by understanding what is important to the people within your organization.
After spending two-and-a-half years at Bain, one of the top strategic management consulting firms in the world, Nat began his independent school career as an administrator. Over the years, he has worn many hats: director of development, director of external affairs, department chair, academic dean, director of technology, unofficial CFO, assistant head of school, and head of school. Analytical, discerning, and full of humor, Nat’s Vermont roots and unusual career path have made him an expert at growing things. From plants to people, teams, and organizations: Nat can plant a seed and do everything it takes to help it thrive.

Carole Everett

Armed with a bachelor’s degree from Barnard College of Columbia University, an advanced degree from the Universita di Siena, Italy and having studied at Juilliard and Manhattan School of Music, Carole Everett has performed as a mezzo-soprano with opera companies and orchestras all around the world. Fluent in Italian and as someone with a level of fluency in French and German such that you would be happy to have her guiding a trip for you in those countries, Carole tops off her multilingual list by also being able to read Latin. A published author with two books related to performing arts colleges, high schools, and summer programs, she co-founded in 1991 and co-headed for 10 summers the Spoleto Arts Symposia. Overlapping with some of that same time, Carole was the Director of Admissions of The Juilliard School for 7 years and then The Nightingale-Bamford School for 10 years.

Those experiences along with a stint as Head of School at The Good Hope School in the US Virgin Islands and additional admissions work at St. Lukes in NYC ultimately led Carole to her role as Executive Director of the New Jersey Association of Independent Schools where she made a significant impact in their program offerings, prominence on the national stage, and membership..

An upbeat people connector, Carole builds strong and effective teams in every organization of which she is a part. Her knowledge of schools runs wide and deep and she imagines possibilities where others may see none.

Evan Hundley

Evan grew up in Seattle, Washington. His lifelong dream was to have a career in Public Policy, and also in education. After attending Whitman College in Washington, Evan completed two Master’s Degrees from the University of Southern California; one in Public Administration and the other in Urban Planning.

Evan began his public policy career working for the City of Redondo Beach, California, in the finance division. He wrote and administered Federal grants, and loved working with the community business leaders.
Evan returned to his home, Seattle, and worked in the City of Seattle’s Personnel Department. This exciting work gave him first-hand knowledge of the complex world of personnel administration policies, hiring practices, and the opportunity to work with city leaders at every level.
Evan next worked in the Office and Management and Budget, where he enjoyed working closely with the City Council and the Mayor’s office. All during this time as an administrator, Evan developed a strong interest in the field of education.
The lure of an educator proved to be too tempting, and Evan became a teacher and taught for 14 years at an independent school in Seattle. Evan finally decided it was time to combine teaching with his administrative background, and became the Head of School at Explorer West Middle School for twelve years.

Evan finished his career in education as an Assistant Head of School for Seattle Academy of Arts and Sciences. One of the duties he enjoyed was interviewing senior administrative job candidates, and making recommendations for hire to the Head of School.

Evan has always had a very special place in his heart for the wonderful parks system in Seattle. He was honored to have been chosen by the Seattle City Council for a position on the Seattle Parks and Recreation Board of Commissioners, where he served for six years. Today, Evan enjoys teaching tennis and traveling in his spare time.

Marcus Hurlbut

The youngest of three, Marc grew up in a tight-knit neighborhood in suburban Boston where he learned to be self-reliant and resourceful. He also spent eight summers at a camp in Maine— a place that celebrated community, the outdoors, athletics and music. This experience led to his love of the water, a lifelong career as a multi-dimensional athlete, a brief stint as a one- time aspiring folk singer, and an enduring commitment to being part of a team.

Marc spent his high school years at an independent boarding school which,
along with his camp experience, guided him toward a 40 plus year career as
an educator and school leader. Early in his career as a school head, he and
his family built (literally) a small summer cottage on the coast of Maine, a life-
changing experience that has now brought joy and togetherness to three
generations of Hurlbuts.

Marc is especially proud of his work founding Breakthrough programs in all three of the schools he headed. These programs reflect his commitment to serve diverse communities of students and families and the responsibility he feels independent schools have to pursue a meaningful and impactful purpose beyond the walls of their schools.

Doug Jennings

Doug has always loved the outdoors—he firmly believes that “nature is our best teacher.” Whether leading student groups up Mount Washington, whale watching in Mexico, or doing a bird count in his backyard— the sense of purpose, balance and collaboration Doug observes in the natural world translates to his work with human organizations.
When it comes to his career, Doug has always prioritized personal relationships. His is an empathetic counselor and fervent learner. As a partner, he takes in the whole picture of every person and organization he connects with, distilling everything down to what is most essential.
Careful, present, and confident, Doug prioritizes establishing a sound and inclusive process. That’s why he spends so much time connecting with his clients— getting to know them and thinking deeply about their best interests. These qualities may also explain his love for eagles and ospreys—how their bird’s eye view allows them to see the big picture without losing sight of the details on the ground.

Deirdre Ling

Deirdre Ling is a woman of firsts: first Vice Chancellor for University Relations and Development at UMass Amherst; first woman and person of color as Head of Middlesex School; and first place in most game nights. (She’s a Bronze Life Master in Duplicate Bridge.)
For Deirdre, being first isn’t about being the “best” — it’s about opening up possibilities for others. Growing up bicultural in America in the 40’s and 50’s and coming of age in the 60’s, Deirdre is an ardent feminist with a deep and abiding commitment to social justice. She has been referred to as a ‘pathbreaker’— someone who is always seeking new ways to knowledge, equity, and inclusivity.
Fun, intuitive, loyal, adventurous, and quick on her feet, Deirdre is dogged in her pursuit to get it right for her clients. She considers herself a cross between cultural anthropologist and a matchmaker. She finds deep satisfaction in listening intently to stakeholders; identifying what they most value; and then helping them find the right leader to move them forward.

Sally Mixsell

Sally Mixsell (Mike’-sul) always knew she would become a teacher. Her favorite birthday present was the blackboard her parents gave her when she was seven. (Her little sister was not so charmed by the gift as she was relegated to being Sally’s student for hours on end.)
While she never thought she would become a school administrator, Sally was always intrigued by how schools work. This fascination led her to zero in on the topic of leadership: she developed several leadership programs for students; moved into academic administration; headed academic institutes; and eventually, designed and taught in a graduate degree program for independent school leaders. Ultimately, she became the guiding head of her alma mater.
Through it all, Sally has been known for balancing hard work with good fun. She is forthright, embraces change, and thinks through the lens of possibility. After 44 years serving schools, Sally joined EC knowing there was still so much more she wanted to do. At the heart of her efforts is a reverence for the miracles of education— miracles made possible by leaders who listen deeply, work purposefully, and care about kids.

Steve Piltch

At a young age, Steve learned the importance of optimism in the face of adversity. When he was eleven, he was in the hospital for several days. There, he met Raymond, a nineteen-year-old boy waiting for a kidney transplant. They stayed up much of the night, and throughout, Raymond kept talking and laughing. Although Raymond’s fears about his future were evident, so too were his positivity and hope. More than anything, Steve remembers the warmth and interest Raymond showed in Steve and how happy Raymond appeared to be alive. Unfortunately, Raymond passed away, but his empathy and courage impacted Steve then and still inspire him today.
Steve has strived to bring optimism and empathy to his 40 years of work as a teacher, coach, and head of school. After teaching and coaching squash for six years at Choate Rosemary Hall, he went to graduate school at Harvard Graduate School of Education. He began his graduate studies by earning two Master’s degrees, one in Counseling and Consulting Psychology and one in Secondary Education, before earning a Doctorate of Education with an emphasis in Administration, Planning, and Social Policy. During his years in the Harvard community, he also had the privilege of coaching the men’s and women’s squash teams while serving as an assistant athletic director. He then became head of school at the Shipley School in Bryn Mawr, PA.
To some, the transition from being a squash coach to becoming a head of school was baffling: How does a coach become head of school? But to Steve, becoming a school head was an extension of what he was already doing in his coaching – namely gathering people together; meeting them where they are, and helping them reach their full potential. That attitude guided his leadership, reinforced the school’s commitment to the education of the whole child, and influenced Steve’s choice to help Shipley to become the first school of Positive Education in the United States.
Steve has balanced his entire career in education with an unwavering commitment to his family and friends. He is married with three children and has eight brothers and sisters. Passionate, caring, and funny, he tries to do the same thing at home that he does at work: open up space for conversation; ask good questions; and show unconditional love and support.

George Sanderson

A morning visit to an independent school outside of Philadelphia was all it took for George to decide that his future would be in education and not banking after all. A close friend had arranged an opportunity for him to shadow a member of the school’s faculty. Chatting with students and teachers, experiencing the hum of a bustling school day, and finding himself smiling from the inside out, he knew that he was meant to teach and be a part of this world. In the midst of a highly successful corporate finance career in New York and London, George made the switch to schools thus beginning a new career that would ultimately lead him to headship. 

Leaving behind the city and the ceaseless business trips his finance position had required, George moved with his family to New Jersey and began work as Associate Director of Admission and Director of Financial Aid for Princeton Day School. Eventually, he was able to make his dream come true. He moved into the classroom and put his undergraduate history degree and finance experience to work teaching history and economics. George never looked back. Instead, he added his business acumen to his school experiences. His training in finance proved to be particularly valuable when he became the head of school at Doane Academy, when he served as a trustee and finance committee member of a number of non-profit organizations, and when he chaired the NAIS committee that oversees financial aid methodology. 

Through the years – as a teacher, administrator, leader, trustee, and, now, consultant – George has integrated his understanding of the business of schools with his deep respect for the powerful impact of an independent school education on students and families.

Carol Santos

A transformational leader with over three decades of experience in the private school sector, Carol Santos is a high-impact educator. Her impressive career as a leader of independent schools recently culminated in her role as the founding Head of School at Dipont Huayao Collegiate School in Kunshan, China, where, since 2019, she has spearheaded the design, establishment, and sustainable growth of this American-style, pre-K through 8, bilingual school.

Upon graduating from college with a B.S. in Economics from the University of Pennsylvania’s Wharton School, she fine-tuned her skills in financial analysis and management as a corporate executive before finding her true vocation in the field of education. Her career in education began in earnest at the Westover School in Connecticut, where she served as Dean of Students, Interim Director of Studies, Assistant Director of Admissions, Director of Diversity, Director of Women in Science and Engineering, Varsity Basketball Coach, Mathematics Teacher, and Class Dean. Earning her Ed.M. from Columbia Teachers College and currently about to earn her Ed.D. in Educational Leadership from the University of Pennsylvania, Carol has also served as Assistant Head at Groton School, Associate Head at Miss Porter’s School, and Head of School at Centennial Academy.

Carol is well-known for her capacity to affect positive change in schools, and she attributes this ability to the work ethic she developed as a student-athlete at Ansonia High School. There, teachers and coaches pushed her to overcome numerous obstacles to achieve both academic and athletic excellence. Like the organization Zeta Phi Beta Sorority, Inc., which she revived at Penn as a freshman, Carol is “action-oriented” and “community conscious.”

Leadership, empowerment, and positive change. These are the contributions Carol Santos has made to the field of education and continues to make as an Educators Collaborative partner. EC is thrilled to have Carol as a member of the team, bringing her considerable breadth of leadership experience and knowledge from both international and domestic independent schools to bear on the search, coaching, and strategic work she does as a partner.

Mary Seppala

Mary Seppala feels most alive when she is deeply immersed in understanding the culture of a school. The variety of schools she has represented in her search work is intentional, seeking out the uniqueness of each environment and allowing her to work with each school community to define their future leadership needs. A teacher, counselor, special education administrator, and school leader, Mary understands schools from a Board, faculty, student, and parent perspective. She welcomes challenge, as demonstrated in her role as the first American and first woman to lead Munich International School (the first IB World school) and then transition to all-girls leadership at The Agnes Irwin School on the Main Line in Philadelphia.
Social justice education is in Mary’s DNA. She has worked in the Middle East, living in a Kurdish Village near the Syrian border; did projects in villages in Tanzania; and had a Fulbright exchange in Argentina. Her passion for multi-cultural work led her to develop the first anti-racist teaching program in a group of Philadelphia Independent Schools in 2013.
Mary is the only EC partner who spent 30 years in public education. Having worked in public, international, and independent schools at all levels—including teaching at the university level—she is masterful in the overlap of education and culture.

André Withers

Originally from Indiana, André has been in independent schools for over 25 years. The initial foray into the world of independent schools was as a Middle School teacher and Advisor in Indianapolis. As opportunities arose, André was able to also find his first administrative role as Director of Diversity. Soon after, and with much success, André was appointed Director of Middle School. Concurrent to the work at those two schools, André was invited to serve on the board of ISACS (Independent Schools Association of the Central States) where he chaired the Equity Committee and was a member of multiple accreditation teams. That valuable work also led to additional service with NAIS. André was a faculty member of the Summer Diversity Institute and subsequently worked as the director of that professional development opportunity for three years.
In 2004 André and his family landed in Washington, DC. While working in senior leadership there, André served a term on the Board of AIMS (Association of Independent Maryland Schools) while also being a sought after presenter nationally and internationally.
With a relational approach, André joined Educators Collaborative in 2022 in hopes of supporting schools and their leaders to evolve in ways that can ensure institutional success.
