Fanny is outstanding!!! Her knowledge of the laser hair removal process, cycles, etc is the best I've experienced (I've had at least 4 others in the past many years). And her "bed side manner" is amazing. She's just awesome and I continue to only see her when I need laser spot treatments

Everyone is very responsive and nice. The only issue is they are often running over an hour late. I'd say 1/2 the appointments I've had have been over an hour late. Dr. Maas is worth waiting for, but it does seem to be an issue that should be fixable with a change in scheduling.

A few years ago I started to develop 'bags' under my eyes. Although I was fearful of surgery I no longer saw myself when I looked in the mirror and decided something had to be done. I made an appointment at the Maas Clinic in San Francisco for a consultation. I walked into the clinic I knew I had made the right decision. Dr. Maas was professional yet kind and understanding of my anxiety. He explained in detail the steps of the procedure from that day's consultation to the day of the surgery through the post-op visits. I am now starting week two post-op and although the results are far from final I am thrilled at the results already! I am deeply grateful to Dr. Maas and the beautiful work has had done!

Staff is professional, friendly and welcoming, and Dr. Maas is exceptional. Highly skilled and knowledgeable, takes time to answer your questions and assure your comfort. I would highly recommend his clinic.

I had IPL treatment and was a little concerned because I have very sensitive skin and not sure how I would respond to the therapy. The staff took extra time with me doing a test spot first to ensure my safety. The staff are knowledgeable, professional, and accommodating. I really appreciate that they listened. Office is very busy but peaceful at the same time which I appreciate. Needless to say I’m going back for more IPL!

This visit with the hygienist did not live up to your high standards nor with my past experiences with other hygienists in your office. She seemed inexperienced and the only term I can think of is "sloppy." I asked for the nitro when she brought me into the exam room and was told, "No, we are not doing that today." I asked if there was any reason why not and she did then go and ask somebody. Eventually, I was hooked up, although I had the feeling she was not quite sure what she was doing. At one point, I felt like to confessing to all crimes because I was swallowing more water than she was being pulled out by the tube...sort of like waterboarding. In all seriousness, I adore Dr. Coi and the fact that I can bring Leila. I love the office and everyone in it, except my last hygienist. If she is still there for my next visit, please do not schedule me with her.
