SPARC BOARD & Staff

ELLEN DYKE

Chair

Attorney, author, and educator

Individuals with severe disabilities have far too long been treated unfairly, inequitably, and unjustly. The words “tikkun olam”, a signature theme of my faith, has taught me not to stand by silently watching injustice, especially when a small act of caring often gives hope and can alter the course of someone’s life.

Every day, SPARC is where people with disabilities feel welcome. I see it every time I visit. SPARC participants are with friends and staff who embrace their hearts, minds and personalities in a way many people don’t. As the father of an adult with a disability, I see how SPARC creates a space of belonging for a population that is too often lonely.

Managing Director, EY

I am passionate about justice and protection and giving my time and talents to organizations that support the advancement of vulnerable persons. Previously, I served on the board of a not for profit located in Western New York that teamed hundreds of volunteers with persons with disabilities to learn to ice skate. It is this intrinsic drive that connected me to serve SPARC and their incredible mission to provide richer, fuller, and healthier lives to persons most in need of physical and social activity.

Serving on SPARC’s board has been a distinct honor and privilege. I firmly believe that every single person should be able to live her or his best life.

I serve on the SPARC Board because I believe in the power of inclusive, person-centered development. As a behavioral health talent development leader and an adult educator, I’ve spent my career helping people grow into what’s next—whether that’s a new skill, a new role, or a new sense of purpose. SPARC’s mission to support adults with disabilities aligns deeply with my commitment to building pathways that honor individual strengths, promote equity, and create real opportunities for contribution and meaning. I’m proud to support an organization that values every voice and helps individuals thrive on their own terms.

Sr. Office Administrator, Juniper Networks

Our son, Kyle, became a SPARC club member in 2007 and as we came to know the other members, their families and their aides, we realized how valuable SPARC was to us and to all of them. The next and last 4 years of his life were spent in the SPARC environment that brought friends, fun, stimulation, activities and rewards to his life and ours. Since that time we have continued to support SPARC as we can and are grateful for all who have come forward to provide the additional support and funding to keep this program alive for the segment of our population that is too often overlooked and underserved.

During my prior service on the Fairfax County Board of Supervisors, I had many opportunities to work with SPARC.

I believe in SPARC and the important work it does to reach and serve young adults with severe disabilities. I am honored to serve on SPARC’s board and to be part of an organization that provides essential services and life-changing programs to some of the most vulnerable members of our community.

Financial Advisor, Edward Jones

Being part of SPARC is more than a board position – it’s a way for me to help ensure that every adult with disabilities has the opportunity to feel seen, supported and included. As a financial advisor and community advocate, I’ve seen how important it is for families to have access to not only resources, but real connection and care. SPARC creates that space. I’m honored to serve alongside others who believe in building a world where everyone is valued, and I’m excited to contribute to the meaningful, inclusive work SPARC brings to our community.

SEG Relationship Manager, NWFCU

My youngest sister was born with Down syndrome in 1982, and that event was life-changing for our family. From that moment on, we were blessed with the opportunity to appreciate how truly special individuals with “special needs” are. While the medical profession may define them by their disabilities, we’ve come to see the incredible abilities they possess.

This realization drives organizations like SPARC to support every individual in achieving a fulfilled life, regardless of their limitations. SPARC not only provides essential services but also celebrates the unique strengths of each participant, helping them thrive in a supportive community.

Through our experiences, we’ve learned that everyone has something valuable to contribute, and SPARC embodies that belief, empowering individuals and enriching the lives of families like mine.
