About Ravi Chittajallu, M.D.

I have had the opportunity of practicing medicine in multiple countries. Because of that, I have an appreciation of how being a physician can positively affect my patient’s lives. I enjoy making a personal connection with my patients in order to provide a comfortable setting where they can talk about their concerns. This allows me to help them understand that I will work with them until their problem is resolved. My practice focuses on my patient’s needs, and I strive to make myself available to them as much as possible.

I highly recommend Dr Ravi and the Digestive Health Associates. I had my first colonoscopy here and was a little nervous not knowing what to expect but he and his team did an awesome job taking care of me. Procedure is too easy and the prep was smooth (pardon the pun). You would not go wrong selecting DHA and Dr Ravi and his crew. Excellent professionals!!

I had a blockage of a heart stent in June, 2020. My cardiologist asked Dr. Chittajallu to see me thinking that some of my chest pains might be caused by some gastrointestinal problems. Dr. Ravi came into my room and it was immediately apparent that this physician is brilliant and secondly that he is a throwback to the physician who cares about the relationship between doctor and patient. He took his time in asking me questions, examining me, checking my charts and then told me that I display all the symptoms of IBS. He prescribed some meds and advised me on how to change my diet in order to improve my health. After my relaease he continued to check on me, to assist me when I had distress and to ensure that my medical problems where not more serious than appeared on the surface. A CT scan and a MRI proved him correct. His office, especially his medical assistant Geepa were attentive, kind, and took care to ensure good communication. If you are looking for the best internal medicine physician in McKinney, call Dr. Ravi Chittajallu. You will not be disappointed. Great doctor, professional staff.

Dr. Ravi is an absolute amazing doctor. The attention to detail he gives is second to none. He explains the whole process to you what’s going on and he completely puts you at ease. I’ve never felt more comfortable around a doctor in my life. His staff is professional and they actually treat you like a person. I drove from a state away just to use this doctor. He will be my doctor from here on out until he retires which hopefully won’t be for years to come.

I only met him on the day of the procedure, but he seemed nice and knowledgeable. The procedure went well and there was good communication with his office staff.
