Skin is our first visual communication with the world around us and tells so much about a person’s history and health status.

My experience with Dr. Hagan and his staff was absolutely FABULOUS. Very professional and caring. I felt very relaxed and in great hands. Dr. Hagan explained everything step by step on what had to be done. After the surgery, his wonderful staff also followed up with the information I needed for my home care. I would most definitely refer any person to Dr. Hagan and his staff for any dermatological situation. SIMPLY THE BEST!!!!! Thank you...

I am very pleased with the care and results. Dr Hagen explained what I could expect from Restalyn, I was surprised how inexpensive it actually was. He was very gentle and took time to allow the numbing agent to work. He also explained that this would continue to work over the next year. One day post injections I have slight soreness at the sites but no pain or bruising. If you’re thinking about it....go for it!

I recommend Dr. Hagen for your dermatology needs. I had the Mohs procedure twice, and am very happy with the outcome. Close to home in Monroeville too.
