About Amity Health DPC

We left the system to build something better — a practice where the doctor actually knows your name, has time for your questions, and genuinely cares about what happens to you. Dr. Tsay grew up in Orange County and trained inside the same system most patients know — one built on 7-minute appointments, insurance constraints, and constant pressure to move faster. He founded Amity Health to restore what mattered: a real doctor-patient relationship, built on time, trust, and continuity. Marshall joined to handle operations and protect the patient experience across both locations. Dr. Yang joined to bring integrative medicine and deeper root-cause thinking to everyday primary care. Cristina joined to help patients address root causes through functional nutrition.

In the practice's own words, from their website.
