Hundreds of happy patients

1st time visit was pleasant! Doctor was very attentive and showed concern for my visit. Ask me important questions. I also was contacted fairly fast from facility for an MRI, that was ordered by Dr. Randolph’s office, that impressed me. I will be going for that procedure early next week!

Dr Walker is highly recommended. If you want a gastroenterologist with great qualifications, great staff, who listens carefully to your concerns, does not rush the appointment, asks detailed questions, this is your doc. I can't say enough good things about him. Many of my family members go to him as well and are very pleased.

Dr. Yanish is tops in his field. I have never had a doctor explain things to me as well as he did! He really takes his time and actually examined my abdomen... He reviewed and explained all of my CT scans.

Dr Drewitz and staff are very efficient and kind. My visit was completed in a timely manner. Dr Drewitz was very thorough and explained medical issues in a way that any lay person would understand. I was treated by him and staff with dignity and respect

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.
