Clinic

Doctors were Aaron Chinn, Heinrick Beernink, Ferdinand Beernink, and Amen Ness. Office assistants were named Lisa Justi, Jan, Linda, Laurel, Beth, and Debbie. Many or all of these doctors are retired now, so the address and phone number could be obsolete. Drs. Chinn and Ness may still be practicing; both Beernincks are retired. 2011: Dr. Chinn says all records were destroyed 10 years ago.

  • I was part of Doctor H. Stewart Kimball�s �stable,� as he liked to call it. Fresh, not frozen, samples were delivered to his office or to various other doctors around the Bay Area as per his direction. The samples delivered to his office were used in that building or taken to other doctors, sometimes to San Francisco or Contra Costa County. I have date and time records of each donation and notation of where it was delivered. Where the sample was finally administered I have no way of knowing. Samples for this facility were generally left at the pharmacy on the ground floor.
