Well Worth the Wait

I came to The Maas Clinic as a first time botox patient. Upon my arrival, the staff informed me that there would be a little bit of a wait due to a prolonged surgery earlier that day. They were very curteous so I didn't mind the wait. As soon as I met Dr. Mass I understood why he was so highly recommended. He had wonderful bedside manner and was very informative about the procedure I was...

Looking Refreshed - San Francisco, CA

I went to Dr. Maas a few months ago, because the circles under my eyes seemed to be getting deeper and I always looked tired. I am in my late 30's and not ready for surgery. A friend of mine suggested Dr. Maas so I went in for a consultation. Dr. Maas suggested filler. I had considered it in the past but had been scared to try it. Dr. Maas showed me photos of his work and made me feel...

Couldn't Be Happier - San Francisco, CA

I have had 3 procedures done now at The Maas Clinic and I must say I am just so incredibly happy with Dr. Maas and staff. He's always answered all of my questions, spent lengthy amounts of time with me and seems to be endlessly patient! In addition to his expertise work, his staff has always been more than happy to help me with any questions and concerns I've had. I'm very big on manners and Dr. Maas seems to be as well.

Feeling Beautiful Again! Thank You Dr. Maas! - San Francisco, CA

There is that thing about aging gracefully.....well, I just couldn't do it. So I researched several plastic surgeons in the San Francisco area. Lucky for me, I found Dr. Corey Maas. It was very obvious after my consultation with him that he was by far the most informed about different procedures and not only mentioned the pros but cons, if there were any. I had been so nervous, and somehow...
