I loved the time Dr. Maas took to explain to me the procedure I wanted to try (Dysport). I felt all my questions were answered and I felt comfortable trying the procedure for the first time. I was amazed at how quickly it was over and the results. The next session, based on my feedback, he tweaked the injection sight slightly and I had even better results. One thing I wasn't expecting, that was a plus, was how less stressed I felt. I guess the relaxation of the forehead muscles made me feel better. I am now a regular customer. My appointment times are quick and easy.

I would use one word exceptional service in every area of patient care. I had a rhinoplasty with a well known plastic surgeon in Los Angeles. The tip of the nose turned up and the surgeon took no responsibility for the results. I came to Dr Maas and he was personable and professional explained the procedure and gave me a visual of what he could do to fix the problem. He was not overconfident like the previous surgeon in Los Angeles he was confident in himself and he listened to what was bothering me with my nose as the other surgeon dismissed what was bothering me and evident in the surgery results. I was never told how to care for my nose after surgery. There was no nose wash given no antibiotic or suction of the nose after surgery. I experienced exceptional care and healing and my results are exceptional. It was so worth it. Yes, Dr Maas is a surgeon that is honest and he is there for you. I would not consider anyone else and I would refer with confidence!

I have been involved with a clinical study and it has been a very positive experience. The coordinator is very organized and on top of all details including appts and diary entries. The office is friendly, helpful and return calls punctually. The doctors are open and listen to any issue of concern. I love the effects of the product and people tell me I look wonderful.

I feel like a princess whenever I visit Dr. Maas and the Appearance Care Center. I had a Facelift almost one year ago and I am absolutely thrilled with the results. As promised, Dr. Maas was very sensitive to my request that I didn't look different just rested and that's exactly the results I got. In addition, the team of nurses that have helped me with IPL procedures have been just wonderful. All worth it!

Going to see to Dr. Maas was one of the best decisions I've made in a long time. I was and continue to be very happy with the results of surgery, as well as the appearance center's staff guidance in improving my skin. I continue to be amazed at how much better I look since coming to Dr. Maas.

Staff has always been very friendly and welcoming. Have not had any major procedures, just fillers and Botox, and was satisfied with results. Also had IPL on arms and thought it was very effective.
