From the reviews

Simply THE BEST Dr. there is. I can write a book to describe my experience but I will sum it up for you. I had Lipo 360 with Renuvion and a BBL. I am a sales rep and work in healthcare so I know and work with hundreds and hundreds of Drs. Dr.

★★★★★ — Roger, Jun 2023

I had my Lipo 360 and BBL done with Dr. Maria Diaz, and I couldn’t be happier with my experience. From the very beginning, she and her team were incredibly professional, informative, and genuinely caring. They made me feel comfortable and supported every step of the way.

★★★★★ — Yasmin, May 2026

I had my surgery with Dr. Maria Diaz and I couldn’t be happier. From the consultation to the follow-ups, she made me feel heard and completely comfortable. Her team also amazing and the massages were the best to help me heal faster. I love my results - I look natural and feminine, exactly how I wanted.

★★★★★ — Nicole, Oct 2025

Dr. Diaz is extremely professional, kind and really took the time to explain the procedure to me. The staff is so sweet as well! I felt comfortable from the minute I walked in for my consultation.

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.
