He was the most honest and sincere doctor you could ever want to care for you. He is a perfectionist and truly cares about his work. After seeing the results of his procedures I am convinced he is one of the best. Just as a side note, I am an RN who has worked with various plastic surgeons. Not only has he operated on me, but my mother, sister and many friends have all been very happy with their results from his work as well.

I had "scarless breast augmentation" by Dr. Diehl and couldn't be happier! He put the incisions on one of the creases in my underarms and they have completely disappeared! I have no scars under my breast or around my areola and my breasts look great. There is no way to tell that I had augmentation, no matter how close you look. I put off my breast augmentation because I was afraid of having a scar either under my breast or around my nipple. I had friends who had this kind and they are very disappointed with the scars. I don't understand why anyone would not do it this way. See Dr. Diehl before you decide.

I had gynecomastia (men’s breast reduction) surgery by Dr. Diehl recently, and my experience was excellent. I usually don’t write reviews, but I want to let anyone who is having this surgery know about Dr. Diehl. My result is perfect. I can finally go wherever I want with my shirt off and feel great. Dr. Diehl is an outstanding surgeon. His surgical skill is obvious to me, now that I see the result, but he really made me feel confident all through the process. He is a great guy to have as a surgeon. He gives you plenty of time to discuss all of the details of the process, and takes care of every aspect of your care.

Stepmother and family friends who had gone to Dr. Diehl. I made the choice to go to Dr. Diehl after my stepmother and several family friends had gone to him. Everyone had nothing but wonderful things to say about Dr. Diehl. From the moment I had my consultation I knew Dr. Diehl was the perfect choice. He is extremely professional and truly cares about his patients. Dr. Diehl turns dreams into a reality!!!

I thought about breast augmentation surgery on and off for a couple of years. As I achieved my goals in the area of fitness, and felt proud of my achievements, the reduction in body fat also caused me to lose the size and firmness of my breasts. After careful consideration, I came across Dr. Diehl's web site and was impressed with his credentials, affiliations with accredited hospitals and his well - rated surgical unit. I decided to take the plunge, and I made the consultation appointment. It was the best decision of my life. Dr. Diehl's staff was supportive and caring and took the time to meet my needs. Dr. Diehl's skill helped me to enhance my symmetry and has fueled my passion for body building even more. Dr. Diehl is the only one I would go to, and I would recommend. Colleen Gilligan

Melissa Weber R.N. going to Dr. Diehl. At my initial consultation all of my questions and concerns were addressed thoroughly in a professional manner. After leaving I felt 100% confident that I had made the right decision about the surgery I wanted, and the qualified surgeon I had chosen to perform it. It has been almost a year since my surgery and I couldn't be happier. I don't hesitate to recommend him to anybody, in fact my mother recently had a breast augmentation done by Dr. Diehl and she looks and feels amazing. Each and every encounter I had with either Dr. Diehl or any of his staff was a positive one. My experience was so wonderful that when they offered me to work in the office occasionally I jumped at the chance. Now seeing behind the scenes of the office and the surgeries I have a better understanding of why all his patients are completely satisfied with their results. He listens to their requests prior to surgery and is an absolute perfectionist in the operating room.

There are no words to express how happy I am with my whole experience at Dr.Diehls office, from my consult to my post op appts. I was well taken care of and treated like I was their only patient:) I went to many consults for my breast augmentation and I felt most comfortable with Dr.Diehl, he answered all my questions and took his time with me. I left my consult knowing he was the surgeon for me:) Ok, so lets talk about my results, the only thing I can say is amazing!!!! My self esteem is back and you can't put a price on that:) When anyone asks me where they should go, I say "only the best, Dr Gregory Diehl" !!!!! Thanks again for everything

There are no real words to express my gratitude to everyone at Dr. Diehl’s office for what they have done for me, but I would like to say thanks for all of their support and care before, during, and after my surgeries. The end results were certainly worth any of the surgery discomforts – and Dr. Diehl and his staff were so professional, understanding and helpful. Found him through a family member.
