Marline- I found this on the sticky thread here. Ticker might have someone too or know if this doc is any good. I would call them -if they have a long wait, they might know someone else.
there is Dr. Harris in Nevada City CA, Dr. Stricker in San Fran
I just looked to see if there is a Lyme support group in CA but there wasn't one. There is one in Arizona-we cannot post contact info here but you should be able to find them. AZLDA - Arizona Lyme Disease Association. They should be able to help you as well.
