Philosophy of Care

My educational background is diverse. I graduated from the American University of Beirut medical school in Beirut Lebanon. I completed my general surgery training at the University of Texas Medical Branch in Galveston-Texas where I was involved in various aspects of medical students’ education as well as a member of the education sub-committee in GME.

I also possess a strong research background as I spent 2 years in clinical outcomes and database research in colon and rectal surgery at the University of California-Irvine. I did a colon and rectal surgery fellowship at Baylor in Dallas where I gained extensive experience in different aspects of surgical approaches from open to laparoscopic and robotic as well as managing complex colon and rectal patients.
