Reviews
Friendly, efficient, respectful.
Very professional? cared about the patient.
Every person who worked with me was absolutely delightful and professional.
Everyone from check-in to checkout was so friendly, made me feel so comfortable and knew I was in good hands.
Like many people I’m sure, I heard horror stories of having the dreaded, embarrassing, and vulnerable procedure done. A friend of mine, who told me about Dr. Sarles, encouraged me to have it done. He said the peace of mind was certainly worth it, and Dr Sarles, and his team, made the process very easy. The hardest part was just making the call to schedule the appointment. From the prep to the procedure and recovery it was a breeze. I definitely recommend Dr. Sarles!
My favorite! He has helped me in so many ways. He is caring, dependable and truly wants the best for you.
The TX Health Surgery Center staff and doctors are very friendly and professional. My procedure was preformed quickly and efficiently. Doctor Sarles has performed many of these procedures for me and has always been very professional and informative with each one.
I recently completed a routine procedure with Dr. Sarles and the experience was A+++, with red carpet care. I had worked with the team previously and they reached out with consistency and dedication to let me know it was time to make a new appointment. That’s what I call Top Notch Care!
Very friendly people good service
Been seeing dr sarles for very long time and have never had a problem with him or office staff. Always polite and explains things so that I can understand what's going on with my problems. I have recommended him to lots of people.

thank you for taking care of me!
Everything went well. Very professional. The Dr. came by to consult after the procedure but I was still out. Never heard from him so I guess I'm good to go for another 10 years? 🤷♂️
Everyone was very kind, patient, and professional…
Dr. Sarles and staff have always made me feel welcome and cared for… My experience once again at the surgical center was very comforting, caring and professional.. P.A. Lillian Sarles is as knowledgeable, warm and caring as Dr. Sarles.. I recommend him highly..
