Leadership & Training SpecialistsBarbara Henry is the visionary founder and Executive Director of Domino Service Dogs (DSD). A Certified Professional Dog Trainer (CPDT-KA) and passionate disability advocate, Barbara combines executive leadership with extensive training expertise in canine behavior, clicker training mechanics, and science-based learning theory.
Barbara established DSD to honor the memory and legacy of her late daughter, Caitlin Tyra Brady. Navigating Caitlin's care revealed firsthand the severe systemic barriers, multi-year waiting lists, and staggering financial burdens—often exceeding $30,000 to $40,000—that individuals and families face when trying to acquire a professionally trained service dog. Determined to ensure that cost, bureaucracy, and physical limitations never prevent a person from gaining life-saving assistance, Barbara created DSD as an accessible, high-standard, community-driven non-profit.
Under Barbara's direction, Domino Service Dogs operates on the belief that everyone deserves dignity, self-reliance, and full community access. She oversees the strategic growth, operational integrity, and donor relations of the organization, ensuring that high-caliber training remains affordable and sustainable for individuals on fixed or limited incomes.
