"Dr Hardi is ok but his office manager has the worst attitude. I was trying to schedule an endoscopy and colonoscopy and she wanted to send me to PG county when Dr Hardi told me it would be done in Rockville. She was rude and didn’t give me an explanation other that it was my insurance but I told her I was paying out of pocket. I was forced to find another doctor. Horrible attitude. "

"A Great Doctor. After 30 years of being my family physician, I really can't say enough good things about him. He has guided me back to health when 5 doctors couldn't figure out (or more likely or didn't care) the cause of my intestinal problems and major weight loss. He helped us get my husband get to the correct doctors when he was diagnosed with colon cancer., and later when I had lung cancer. He is thorough, professional, caring, knowledgeable, and respected by other doctors."

"I've been treated by Dr. Hardi for many years and have always been very satisfied with his solutions to my gastroenterological issues. He has also successfully treated me for other medical issues which has saved me time, money, and the inconvenience of having to see other doctors. In sum,, I would recommend him to anyone."

"I had my follow-up visit/ colonoscopy with Dr Hardi yesterday. He was professional, as always, made sure to talk with me prior to and after the procedure. The ambulatory surgery center was spotless and the staff helpful and professional."

"I have been to 6 different GI doctors before finding Dr. Hardi. He has been the first to actually help and listen to me. After my very first consultation appointment he did a colonoscopy the very next day. His since of urgency and caring nature meant a lot to me as I’ve been dealing with this for a while trying to find someone to help. He immediately helped me, and he doesn’t make you feel like you have to prove you’re actually sick, (like other doctors do) he just believes you and listens and genuinely wants to help people. If you’re looking for a GI doctor, I would 100% recommend Dr. Hardi."

"I have been seeing Dr Hardi for almost 15 years and I find him the most knowledgeable gastroenterologist I have met. He cares immensely for his patients. During my first visit he explored my medical history in a comprehensive fashion. He encourages questions and respects the individual needs of his patients. Dr Hardi also has excellent diagnostic abilities. He actually saved my life by detecting and removing a precancerous polyp from my intestines during a colonoscopy he convinced me to have after hearing my symptoms. He is always very personable and friendly and takes the time needed to clarify his suggestions to make me feel comfortable about them. "

He is always very professional, listens attentively, examines very thoroughly and is very careful in assessing my condition. He is clear in explaining the issues and the procedure he recommends. He is very knowledgeable in his area of expertise but he also knows the best doctors in the area and his referrals are always top notch. Dr Hardi goes out of his way to give his patients the best available care and I feel very safe in his care."

"I have been under the care of Dr. Hardi for more than a decade in connection with my ulcerative colitis. Dr. Hardi is an empathetic, thoughtful, and attentive physician who collaborates with his patients in determining effective care that has patient buy-in. I have consistently felt as though Dr. Hardi is genuinely invested in my health and well-being, as best evidenced by his check-ins to inquire about my condition even during periods when I have lived outside the DC Metro Area. I highly recommend Dr. Hardi to anyone looking for a GI in the area."

He’s an excellent clinician, insightful, direct, thoughtful, and an overall caring individual, all characteristics that have cemented our long patient-doctor relationship.

I have recommended him to many friends and family members who are all grateful. "
