Forefront Dermatology
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...

He is, with out a doubt, one of the most professional, caring physician's around. What Iike about him is the fact that explains what he is going to do and what the outcome will be. Excellent doctor. P.S. He calls the following day of the procedure to see how you are doing.
