My Mentors

Dr. Richard G. Farmer
I am writing this letter on behalf of Rajiv Sharma, with whom I worked 5 years ago when he was in The GI unit at the University of Rochester, New York.

I was the Chief of Gastroenterology at University of Rochester, NY from 2003 to 2009 and then continued there for two years before my retirement.

I worked very closely with Rajiv and he was an excellent GI Fellow. He had good relationships with patients, reviewed the case concisely, and a constant interest in the clinical situation. He was particularly interested in IBD and its complexity. I was planning retirement but I was called to take over GI at URMC and I kept my home in DC for “just a few months” but stayed for 8 years. This enabled me to have an apartment giving a very unusual situation now days—an apartment. Therefore, Rajiv and one other GI Fellow came frequently for an unusual form of modern GI teaching.

I found this old-time teaching, there was a thrill, for each of us and am proud of him as a gastroenterologist which greatly benefits patients.

He was good with endoscopy, related to the patient, reliable, and an eager worker. I think he would be a fine GI physician.

I’ve been a patient of Dr. Sharma’s for the last 3 years and he has helped me get my Ulcerative Colitis under control. I really appreciate his approach to wellness because he looks to solve the problem rather than simply alleviate symptoms. He puts a lot of emphasis on natural gut health. He is personable, empathetic, and eager to help.

I have used Dr. Sharma as my go to gastroenterologist. I have no hesitation in contacting him for any questions concerning patients or other GI issues. My patients enjoy having him as their GI doctor especially those with chronic issues that need his level of expertise.

— Dr. Brake Jr., Referring Doctor


Dr. Sharma is a professional and dedicated physician with a personalized approach to patient care. The health care system needs more physicians like him. I would feel very comfortable with my family under his medical care

— Dr. AA, Referring Doctor


Dr. Sharma has been the GI doctor for my family for almost 4 years. Ever since answering his calling to
open a practice in Terre Haute, we have made the choice to continue seeing Dr. Sharma even though it
is a 4-hour round trip drive to do so. His approach to patient care involves both conventional and proven
holistic medicine, focusing on the whole body. We are certainly looking forward to a continued
relationship with Dr. Sharma for all of our future GI needs.
