Our experience with Dr Arun has been only positive. We appreciate how he listens attentively when you speak and always takes his time to explain matters thoroughly. He has a wealth of knowledge and was accurate with the diagnosis from the beginning. No less important is Dr Arun's kind and caring attitude. It has been a wonderful experience having him as our doctor.
