Our Services


"I visited Dr. Azmuddin for a routine colonoscopy, and he did an excellent job. He is very competent, intelligent, and friendly. For the first time, I experienced almost no recovery time from the procedure. After a short stay in the hospital, I walked out with my husband to enjoy a large breakfast. I am also pleased that Dr Azmuddin gave me a choice of 2 good hospitals: Houston Methodist-Willowbrook and St. Lukes. I chose Houston Methodist, and was very happy with all of their services."



"Dr. Tal Raphaeli was the best for my procedure. I literally haven't felt like this since I was a teenager. I truly thank Dr. Raphaeli for getting me back to normal. I would definitely refer him to anyone."



"I chose Dr. R after extensive research online since I needed colon cancer surgery. I am SO HAPPY that I did!! Both surgeries went beautifully! Dr. R is very calming, responsive, knowledgeable, and professional! His staff is warm and responsive, too. I can't recommend him highly enough!!"



"Dr Azimuddin is a great surgeon. Surgery was great!!! Would not use anyone else!"



"I normally do not leave reviews, I am almost 4 months out from my surgery. I was so impressed with Dr. Azimuddin, he was very caring and empathetic with my concerns about my colon fistula surgery and post op pain management and my medications that I just could not stop taking that I had been on for years, He took the time and sat at his desk with me and went over my medications, records and concerns ( that I had. Dr Azi did not know, but my daughter was the one who found him as I had been to another facility and decided I was not going to do this surgery, but after talking with Dr. Azi, I just felt like I was in good hands. I could see he took his work, patients and skills very seriously. Every staff member who worked with him had nothing but great things to say about this Dr. and everything we discussed; Dr Azi lived up to his words!! The ERAS pain management worked incredibly well with me, I was surprised how well it did work, that I did not need any opioids and I was not in any pain with this protocol, I was up and walking pretty quickly after surgery and released to go home 2 days after my surgery. During my last appointment, I joked with him and asked if he could do any and all my surgeries I would need because back in the day, General Surgeons were allowed to. My family and I are so grateful for this Dr.! Thank You Dr.Azi, you were my last interview as I was giving up on the medical establishment..... YOU ROCK!! Deb"
