From the reviews

The level of care that I received from Dr. Diehl and his staff was wonderful. He took his time and explained exactly what I needed to have done and after the procedure called me with the results. Fortunately I didn’t have breast cancer but I did have a type of benign tumor that needed to be surgically removed.

★★★★★ — Angela, Oct 2021

I was so blown away by the staff at the breast center. They were all so helpful and kind. Dr. Diehl is such a wonderful honest kind man. He didn't push for any unnecessary procedures but rather gave me the real analysis with a good plan for the future to keep watch over my health.

★★★★★ — Cindy, Oct 2018

I just want to say Thank you so much doctor! Dr Diehl is amazing, I only have gratitude for the kind way of treating me, explaining and helping me with my anxiety about the result of breast cancer and also the lumpectomy that he did.

★★★★★ — Isabel, Jun 2026

I generally do not take the time to write doctor reviews, but after seeing Dr. Diehl, I decided I needed to. All I can say is wow! I cannot say enough good things about him. Dr. Diehl is probably one of the nicest doctors I've ever met.

Researching a tummy tuck?

A tummy tuck (abdominoplasty) is major surgery with real risks and a recovery that usually runs several weeks — this page is a starting point for finding a surgeon, not medical advice. The most useful next step is a consultation, where a surgeon reviews your health history, examines you, talks through your options, and gives a personal quote. Bring questions and don't rush the decision.

Questions worth asking: Are you board-certified in plastic surgery (and can I verify it)? Where would you operate, and is the facility accredited? Can I see before-and-after photos of your own patients? What are the risks and the realistic recovery timeline for me? What's your revision policy if something needs adjusting? Whatever a listing says, always verify certification directly with the American Board of Plastic Surgery (ABPS) at abplasticsurgery.org, and discuss your candidacy, risks, and recovery with the surgeon.
