Normally I don't go out of my way to write my opinions online, but this experience was so pleasant I really thought I should...My 17 year-old daughter has suffered from severe acne for over 3 years now. A beautiful girl behind the marks, we were beginning to wonder if the scarring would be so bad she would need surgery someday to remove it. We heard from a friend to try one more dermatologist, who'd produced some amazing results in their son's acne...Dr. Renner was extremely pleasant and conscientious of eliminating Stephanie's acne. Stephanie did Dr. Renner's routine and found the acne diminished in 2 weeks. We were so thrilled to see her face coming back! It took some time, and there is a little scarring, but Dr. Renner gave us hope at a time we were ready to give up! She was a wonderful doctor for us, gave us some great extra tips for keeping the acne at bay, and I just want to say thanks, Dr. Renner!
