The Maas Clinic Reviews
I cannot say enough good things about my experience with Dr. Corey Maas at the Maas Clinic. My visit was for a consultation regarding a nose injury bump. Dr. Maas is incredibly knowledgeable, professional, and friendly. He listens very well, and, importantly, gave thought to and clear answers about everything I asked, and also other things that he thought I should know, but that I hadn’t known to ask, in understandable and patient detail. He gave me a clear plan for going forward, which was important to me. I was very impressed. His assistant, Annie, was also very impressive. His clinic is clean and inviting, his staff professional and friendly. I felt that I was well taken care of as soon as I entered, and all through my visit there. I recommend Dr. Maas very highly.
I love this place and I love the ladies that work here. Alison, Sydney, and Tina to name a few of the ladies that always help me feel my best. I have done the scarlet 3 times now and i love this new service. Microneedling is def the way to go. Keep up the good work Maas Clinic!!
Dr. Maas is an exceptional plastic surgeon due to his exceptional skills and genuine care for his patients. Unlike many other doctors, he devotes time to addressing all your questions and thoroughly explaining the procedures and expected outcomes. I am willing to travel from Washington DC to seek his treatment, as I trust his ability to consistently deliver natural-looking and flawless results.
