Dr. Ramzan is the best gastroenterologist in Phoenix. I have Crohn's disease, and he has been taking care of me for over 10 years. I had a bowel resection in 2004 (under the care of a different doctor), and was told I was at high risk for recurring surgeries. I switched to Dr. Ramzan, and he has kept me off the operating table and away from further surgeries ever since. His knowledge of the field is top notch and has the ability to explain things in a way that I can understand. And he is incredibly compassionate and caring. This compassion also carries over to his nursing staff and front office. Nurse Tara is the best nurse I've ever experienced (I get injections once a month so I ought to know). I am so grateful to have them; it brings a tear to my eye as I write this.
