      I was very impressed with Dr McGowan . He was very attentive and helpful. He was very knowledgeable and understanding. I told him that this visit with him was also very educational.

      I just cannot say enough about my experience at the optimal Clinic from the scheduling to the providers they were all top-notch and are exactly why I decided to make the 6-hour journey to UCSF. I was absolutely not disappointed.

    Please check with your health insurance plan regarding coverage for this type of care. Not all providers at UCSF Health are covered by every insurance plan.
