Experience was everything I hoped for. Waiting room is comfortable, and I was taken back quickly. The staff communicated very clearly about what to expect for the procedure, and took lots of photos for me to see. Dr Posten was patient explained to me exactly what he was about to do. Follow up to remove stiches was a quick visit too, and all went smoothly.

Had a really nice experience with Dr. Posten and his staff. In addition to their generally warm demeanor, I had the feeling they were looking out for me on the financial end of things, as opposed to trying to maximize their take. I was expecting to pay a minimum of $2,500 up to $5,500, but it wound up costing me only about $1,500. I thought Dr. Posten was kinda brusque in initial consultation, but he was kinda funny on surgery day and in follow-ups. And nurse Laura was particularly personable.

Dealing with skin cancer and the what ifs of the diagnosis is a challenging time for most patients. It was a great comfort to know that Dr. Posten was a skilled expert in Mohs surgery and the outcome in my case was excellent and the scar is minimal, neat, and nearly unnoticeable. Dr. Posten and his staff are professional, compassionate, and kind at every step of the process, taking time to explain each step and to answer questions. I would highly recommend Dr. Posten and his team to anyone.

My father is a patient at Advanced Dermasurgery Associates. Dr. Posten, Dr. Momin and their entire staff were AMAZING to him! Thank you to the staff for taking the time to explain the surgery to my dad and for helping him feel at ease during a very stressful time. I would highly recommend Dr. Posten to anyone looking for a Mohs surgeon! He is very knowledgeable, has a great bedside manner and truly cares for his patients.

Dr. Posten removed some skin cancer for me a few years ago and I was very satisfied with my treatment and results, so of course I returned to him when I was recently diagnosed with some new cancer. Being diagnosed with any type of cancer is very stressful, so I appreciate the fact that Dr. Posten and his staff are friendly, patient, and willing to answer questions. I have recommended him to friends and will continue to do so in the future.

Dr. Posten did a cancer removal surgery on my father's face. They did not do a medical history until right before the surgery. They then realized that they could not use the same anesthesia that they had planned. My Dad asked what the options were the Dr. Posten looked straight at him and said Pain and then started cutting into his face. My father had to find another dr. the next day to do a graph on the area that Dr. Posten cut out. It was like something out of a horror movie. He should not b
