Waited a long time in the waiting room for the dr.....was very short with his examination and minimized my concerns. Basically shutdown any questions I had for him and was very rude. I WOULD NOT recommend him! J.Chew Lefshu

By far the most unprofessional and incompetent doctor I have ever encountered. Bedside manner is terrible and his ability to listen is non-existant.

By far the most horrific Medical Professional I've ever encountered. His ethical and moral compass is Tainted. He has no genuine care and his inability to listen and provide information in an understandable manner is confusing and horrendous. If you value your health find a medical professional who genuinely cares about it as much as you do and this doctor is not him

Dr. Diwan treated me in 2005 while I was as in patient at HNW Medical Center he saved my life, if it had not been for his course of treatment I would not be here today. I have continued on as a patient of his since then and would not see ANYONE else. Excellent bedside manor, he remembers you and is a caring professional. His office staff is second to none.

I was critically ill when Dr Diwan treated me, when my regular doctor had given up Dr. Diwan who was also treating me stepped up and changed the course of treatment changing antibiotics and just treating me instead of deciding to take me out of ICU because it was a waste of money to continue to care for me and also that there were other patients who needed the ICU unit and the ventilator more than I(my regular Dr expressed this to my family) I have seen Dr. Diwan since 2005 and her is the best in everything he does.
