Patient Comments (4)
pleasanton, ca |
It took 15 minutes for someone to even come out and check me in. Then, they gave me forms that already had someone's name on them in places (I had just crossed it out) so they made me fill them out all over again. After One Hour of waiting I had still not seen the doctor and was told there was stil one person ahead of me. Dr. was okay; not very friendly. Follow-up visit was a total waste of time; he just said some very impersonal stuff you would say to anyone.

Exceptional clinician. Caring and knowledgeable.
in Walnut Creek, CA |
I find Dr. Mark to be not only uniquely competent in his profession, but remarkably thorough in his assessments. I switched from a Walnut Creek veteran to Dr. Mark about ten years ago and it turned out to be one of the best decisions I could have made.

I saw a few doctors for my condition and Dr Mark definitely resolved my concerns. Great doctor and staff.
