Yes. At this time, I am only serving patients in California.

Yes! I routinely prescribe medications, order lab tests and imaging, and refer to other specialists as needed. These orders will be processed through your insurance as usual.

Medications, labs, imaging & specialist referrals will be covered by your insurance as they usually would be.

Not everything will be covered, but I will happily help advocate for your insurance to cover medications and tests I order.
