Jimmy Zhang

Founder & Advisor

Jimmy Zhang founded Accesso Care to fulfill his vision of compassionate, quality care for elderly residents in nursing homes—a need he recognized as especially critical following COVID-19. With over 15 years in the nursing home industry, Jimmy saw firsthand the gap in caregiving that prioritizes dignity and empathy. An immigrant himself, arriving in the U.S. at age seven, Jimmy established Accesso Care with a commitment to serve the well-being of both caregivers and those they support. Although he is no longer actively involved, his vision continues to shape Accesso Care’s mission and values.
