Dr. Kazanjian is a Health Sciences Clinical Professor in the David Geffen School of Medicine at UCLA. 

Dr. Kazanjian was raised in Los Angeles and received both his medical and undergraduate degrees from UCLA. He completed his General Surgery residency at the Ronald Reagan UCLA Medical Center, during which time he spent two years as a fellow in cancer research. He then completed Colorectal Surgery subspecialty training at the University of Minnesota—the oldest and largest Colon and Rectal Surgery training program in the country. He is board certified in General Surgery and Colon and Rectal Surgery.  He began his career as a faculty surgeon in 2009 as Assistant Professor at Loma Linda University Medical Center, where he established a high volume colorectal surgery unit and later served as Chief of Colorectal Surgery. In 2014, Dr. Kazanjian was recruited to join the UCLA Department of Surgery as Chief of Colorectal Surgery and led the program to significant clinical growth and advancement. 

A highly regarded clinician educator, Dr. Kazanjian emphasizes multidisciplinary care and minimally invasive surgical approaches. He has one of the most extensive experiences with robotic colorectal surgery in the Los Angeles area. His clinical interests and expertise include Colon and Rectal Cancer, Inflammatory Bowel Diseases (Crohn's and Ulcerative Colitis), and anorectal disorders (hemorrhoids, anal fistula, pilonidal cyst, rectal prolapse).  Over the course of the first decade of his practice, Dr. Kazanjian performed over 4000 operations, half of which were major abdominal colon/rectal operations, and the others were outpatient anorectal surgeries.  Over 85% of abdominal operations are performed using minimally invasive laparoscopic or robotic techniques to promote quicker recovery and discharge home from the hospital. This includes an extensive experience with minimally invasive sphincter-preserving surgery for rectal cancer and J-pouch surgery for ulcerative colitis.  Traditional open surgery is reserved for the most complex, usually reoperative cases.

In 2015, Dr. Kazanjian established a satellite office for UCLA Colorectal Surgery in Santa Clarita to help facilitate easier access to consultations, outpatient surgery, and follow-up care for patients in northern Los Angeles and beyond.  All major inpatient abdominal surgeries however are performed at Ronald Reagan UCLA Medical Center.

Dr. Kazanjian is the recipient of several awards for teaching, research and clinical excellence, including "Top Doctor" by Castle Connolly and Los Angeles Magazine.
