Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

very thorough physician-care provided is excellent scheduling however is a problem- multiple tries to get appointments/ also on call service recommendations not always safe/I would have lost a family member if I had not gotten them to the ER when I did despite advice to wait until monday

My Dad was in the hospital and it was determined he needed a heart cath with the very real possibility of a couple of stents implanted. I called the hospital room Dad was in to find out when he'd be going down for the procedure …. Dr Greathouse happened to be there in the room, took the phone from Dad, explained everything they'd be doing, and asked if I would like a call back after he was done. As if that wasn't enough, he personally called me back afterwards to let me know how everything went - that is truly going " above and beyond", as I never had the Dr actually do the call back. Thank you Dr Greathouse - you are an outstanding doctor, and an even better person!

Dr. Greathouse has been the doctor for my husband and me for years now. He is truly a fine man and an excellent doctor. I know he cares about us and our medical status. We have recommended him to many people and are happy that they agree with us. We totally trust him and would tell anyone to feel confident in his care.

He is a very compassionate doctor who explains things well and is very competent professional. I recently had a cardiac cath done and was very nervous about it...he was so good at calming me and performing the procedure that I didn't feel anything. The plug used meant only being flat for 2.5 hours. I've had no bleeding and feel good! The hardest part is getting checkup appointments but after having a procedure or hospitalization, the office called to set up an appointment! Unheard of!

A very good doctor and what a nice man. He takes the time to listen to your concerns and then gives clear concise answers. I have been seeing him for more than 12 years and would highly recommend him to anyone needing a cardiologist.

Dr. Greathouse was professional but personable. He eased my mind with considerate words of encouragement based on so many years of experience. He listened to me and answered all of my questions and concerns with a smile. I didn't feel rushed and came away from appointment feeling wonderful!
