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.

Dr. Hess has been my cardiologist for many years and he is wonderful. I never feel rushed and haven't had long waits. He explains my test results well and explains life style changes that can make me healthier. I took his advice and am in much better health now. Thank you Dr. Hess!

Dr. Hess is amazing. He took me very seriously from the start and put me on a medication that is already making my symptoms less drastic. I highly recommend him.

I would highly recommend NOT using Dr. John Hess. He actually should be ashamed to call himself a Doctor. He actually lied straight to my face and never apologized for his wrong doing. It's a long story and very sad but all I can tell you is don't trust him.

Dr. Hess has been the cardiologist for our family for many years taking care of different maladies of the heart for several family members. He is a rare breed in that he personally takes your BP, listens to your heart, looks you in the eye and answers your questions. You never see a nurse practitioner. We feel you have to talk to any medical practitioner, ask as many questions as you can and work with the doctor to keep yourself well. We work with him. Dr. Hess cares.

I have been going to Dr. Hess for 35+ years and have yet to have anything other than positive things to say about him or his care. My family has a history of heart problems and he has always been patient, thorough and taken care of any of my concerns before he leaves the room. Waiting times vary as there are times he is called to the hospital for emergencies and is running behind. I'm just glad I am not the one who needed his time away from the office.
