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!

Dr. Maas has good bedside manners, and I have confidence in him, and feel comfortable with him. He listened to what I stated that I wanted done, and he explained to me how it could be done. He took the time to answer my questions without me feeling that he was too rushed to spend the time with me. I am pleased with the results from my filler. His assistant, Raquel, I believe her name is, was polite and friendly.

Dr Maas thoroughly discussed procedures which was great, but the procedure itself was not as precise as I have had from other doctors. There was no talk of how much product was being used. Shots were large and not spread out which was painful. Procedure took place an hour and fifteen minutes after my scheduled appointment (but they compensated on price which was great).

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.
