Our Families and Patients

Dr. Stone acquired what is now referred to as “Yorba House,” a residence with six beds, managed by the dedicated Eva. Dr. Stone gave up his own vehicle, a 1975 Ford Country Squire, so Eva could drive residents to meetings, appointments, and grocery shopping. Over time our commitment to accessibility continued, and now we have ten vehicles available to ensure our community members can easily get around and receive the support they need.
