About
At Amity Health, Dr. Trevor Tsay and Dr. Cindy Yang deliver direct primary care across two Orange County locations in Costa Mesa and Orange. The practice covers 95% of primary care needs for a single monthly fee of $110. Members reach their doctor anytime by call, text, video, or email. Same or next-day in-person appointments keep wait times at zero.
The clinical scope at Amity Health runs deeper than standard primary care. Functional Nutrition, led by registered nurse and functional nutritionist Cristina Terwilliger, integrates fully into the membership model. The practice offers in-office procedures including EKG, spirometry, IV therapy, and PRP. Amity Health partners with Quest Diagnostics for wholesale lab pricing and collaborates with Thea Health for specialist e-consultations at no added cost. Veterans can access PRP at no charge through the practice's Shots for Soldiers program, which covers up to two veterans each month. The practice welcomes LGBTQ+ patients and serves the full Orange County community.
