“First visit to this doctor or any dermatologist for that matter. Dr. Petr is very nice, professional and easy to talk to. I had a few spots removed and he did a great job and is very thorough with his exams. The wait was minimal. I was called back to the room within 5 minutes of my appointment time and the doctor was in 2 minutes later. Excellent visit, great doctor, and I would easily recommend him to anyone looking for a dermatologist.”  – Anonymous

“Dr. Petr is a good doctor. He takes the time to examine you and listen to your concerns. His staff is very professional and courteous.

“My family have been patients for over 20 years. We are very happy with Dr. Petr’s care. He is gentle and very caring.”  – Anonymous

“I have been a patient of Dr. Petr’s for over 20 years. In January 2012 my husband and I moved to Albany, GA. I have continued to make an appointment any time that I went back to Texas to see family because I just couldn’t imagine finding another doctor like Dr. Petr. I realize now, I must find a doctor closer to where I live. This is very hard because Dr. Petr is truly one of a kind!! Dr. Petr has been my doctor through countless skin cancer problems. He is so amazing, and I have always trusted his ability to take care of my skin! His staff reflects his caring attitude! I wish he and his office staff would move to Georgia!! Thank you, Dr. Petr.”  – Anonymous

“I went to see Dr. Petr in December for an annual skin check up. He is always exceptionally thorough. This time he found a couple of spots he was concerned about and so he scraped them off. Pathology results revealed one of the spots, on my right face cheek, needed a follow up visit to have a more thorough removal. Being as how this was right in the middle of my cheek, I was concerned about how scarred I would be. But since I AM 57 years old, I have several smile wrinkles. So, when I went in to have the offending lesion further removed, I asked Dr. Petr if he could possibly make the scar match or fit inside the natural wrinkle. Dr. Petr took the challenge… and OMG… he did such a fabulous job! The scar is healing quickly. I can’t believe how well it blends in with my natural wrinkles… when I smile, you cannot tell it is a scar! This was surgery above and beyond the ordinary. Dr. Petr is very compassionate and meticulous every step of the way. He is respectful of my potential modesty, and he is clearly passionate about his profession. Best dermatologist I’ve ever been to (and I’ve been to a total of three others).”  – Anonymous
