Dr. Azimuddin is also an accomplished ceramic tile artist and many of his large scale ceramic murals are installed in public places. He believes there is a deep connection between creating intricate ceramic art and the art of surgery. Being a Colon-Rectal Surgeon he naturally loves to dissect, carve and create with his hands. After a day’s work with the scalpel & forceps, he relaxes with the brush and glaze to create calligraphy on ceramic tiles in the evenings. In doing so, he finds peace and tranquility and this is his spiritual escape. This is his hobby and his passion! Dr. Azimuddi invites you to take a look at his art:


"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."



"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"



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



"I had a colon surgery from him, great Dr, took very good care of me, I will not go to other place or another Dr but him"



"The Best! - I had hernia surgery by Dr Azimuddin on March 5th and if it were not for the band aids and my hernia bulge gone, I would not have known I had surgery. On the pain scale 1 to 10. It has been a zero since the minute I woke from surgery. The medical staff at Memorial Houston Northwest were the nicest people."
