From the reviews

I cannot say enough good things about my experience with Dr. Corey Maas at the Maas Clinic. My visit was for a consultation regarding a nose injury bump. Dr. Maas is incredibly knowledgeable, professional, and friendly.

★★★★★ — Sara, Jan 2025

Was totally impressed with Dr. Maas and his staff. I wanted to look “ natural” but fresher and still like myself. When I left I felt “ renewed on the outside” which made me feel great in the inside, I was smiling as I walked back to my car! Incidentally, before I ran out of meter time they took care of it for me.

★★★★★ — Lisa, May 2023

Maas Clinic is a friendly environment. You feel very comfortable to trust them with your procedures. Dr. Maas is wonderful, he’s friendly and most importantly very skilled. He takes the time to explain and answer all your questions and help with your concerns.

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.
