"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. Azi is a life saver! He diagnosed my rectal cancer and jumped right into action. He literally pulled out his cell phone and began consulting with an oncologist and radiologist. Dr. Azi is the type of doctor that truly cares about his patients and will do anything ensure the best care. I am forever grateful for him."



"Fantastic doctor, best bedside manner"



"I found Dr. Azi in 2018 when I was diagnosed with colon cancer. I was extremely impressed from the first visit and trust his judgment on what needs to be done. He has an awesome bedside manner and truly cares for his patients. (His sense of humor isn't too bad, either!) He is very thorough and made sure I understood exactly what was going to happen. He is THE best... I wish I could have him as my PCP. 10 out of 10!!!!!"
