The staff was supportive and caring. They did everything possible to ensure my comfort. The office itself is lovely and promotes a relaxing atmosphere which is important if one is undergoing a treatment for the first time.

Dr. Moss is Knowledgeable ,And Professional

With a terrific staff.

I previously had treatment at a clinic with a nurse but unfortunately that nurse injected filler in to the wrong place on my face.

I was afraid to have the filler removed and afraid to try filler again after a scary experience.

One of my girlfriends sees Dr. Moss and has for years and highly recommended him I tagged along to her appointment and was very happy with my results and have returned since.

I’m very happy with Dr. Moss and my results. I feel that Dr. Moss listens to my concerns and my needs and did not overfill my face just to sell product, which had been my previous experience.

Very happy

Everyone at The Maas Clinic is cordial and professional. They are very skilled and can answer any question I have. They are dedicated and caring and spend time with you to make sure your experience is a positive one. I have recommended Dr. Maas and his wonderful staff to all my friends, they help me look and feel my best! You are in excellent hands at this office and they will encourage you to feel welcome. I would easily go out for a cup of tea with any one of them!

Dr. Maas is absolutely incredible—from patient relations, to time spent and attention given, to his undeniable talent. I never have to worry when I put myself in his hands. He is committed to a natural but enhanced look. Thank you for helping me to feel the very best about myself!

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.
