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."
