Dr. Marquez and her team have changed my life. From my first consultation with her to now being 1-year post-op, I have felt so happy and comfortable with the care I've received. What I most appreciate about Dr. Marquez is that she isn't just interested in physical symptoms and results -- she is truly concerned with addressing her patients' needs in a holistic way, and treating them like individuals, each with their own story. I'll never be able to say enough good things! I have lost nearly 100 pounds this year and am a completely new person. I guess I do have one regret, and it's that I didn't find Dr. Marquez and her team sooner. Thank you from the bottom of my heart!

THE STAFF IS GREAT AND THE WAIT TIME WAS MINIMAL. THE OFFICE AND WAITING ROOMS WERE ALL FREE FROM CLUTTER AND IT WAS IN VERY NICE ORDER AS USUAL. I DID HOWEVER GIVE MY PROVIDER 4 STARS FOR NOT BEING ABLE TO SEE MY DOCTOR THE PAST TWO VISITS. THE PRACTIONIER WAS VERY HELPFUL AND EXPLAINED EVERYTHING WELL, HOWEVER I WOULD HAVE LIKED TO SEE MY SURGEON SINCE I AM HAVING A PROBLEM AT THIS TIME BECAUSE MY LOSING WEIGHT IS AT A STANDSTILL.

I love Dr. Marquez, and this was my first time to see her PA, who was wonderful as well. Their new Round Rock location is very nice, and there was virtually no wait.

This was a follow up exam with Dr. Marquez and, as always, she was extremely professional and, at the same time, personable and caring. The best surgeon in Austin!

My surgery experience & week after we’re absolutely amazing!!!! Very little pain & the medication “cocktail” for recovery was wonderful- I definitely felt better right away because of no opioids!! Dr. Marquez, Isabel, & staff at Southwest Bariatrics is phenomenal!!!! I would highly recommend her to anyone needing gastric bypass!!!!
