As an international non-profit organization, AYUDA provides free dental care to those who need it most. Dr. Zech is an advisor and participating member of AYUDA. The program is affiliated with the Ostrow School of Dentistry of USC in Los Angeles, CA. It was founded over 48 years ago by a gentleman named Harris Done, DDS. It originally served Native Americans on reservations. Monthly clinics are currently held in the metro area of Los Angeles with an annual international trip to countries with underserved populations. Last years' clinic was in Anta, Peru where Dr. Zech had the opportunity to volunteer as faculty and assist his daughter, Kathy, a dental student. AYUDA is in the process of merging with "Doc in a Box" another non-profit organization headquarted in Newport Beach, CA. This will allow for expansion to other dental schools throughout the US and Canada and will expand dental outreach to additional underserved areas in North America.
