Dr. Drewitz is the best. He is kind, caring and very easy to talk to. He takes time to listen and does not make an appointment feel rushed. The office staff has also been great.

I just had my 5th colonoscopy and cannot say enough good things about East Valley Gastroenterology and East Valley Endoscopy! Doctor Panossian is an excellent physician and ALL of both company’s staff are warm, caring and professional. From the initial consultation to waving goodbye after the procedure they were a model of efficiency and team collaboration – it was like watching an Indy 500 pit crew in action!

Affecting many people in Arizona, ulcerative colitis and Crohn's disease are the most common types of inflammatory bowel diseases (IBD). Every year, nearly 70,000 new cases of IBD are diagnosed across the US in adults and children, with many being diagnosed before age 35. While inflammatory bowel disease is a chronic condition that cannot be cured, it can be treated with proper care.
