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.

Can’t help me
Said he didn’t know what was causing the pain in my abdomen. Prescribed pain medication, which just masks the problem. Pain is an alert there is something wrong.

Terrible doctor
Failed to listen to anything that I said in my visit, was rude and hostile. I’m finding a different doctor- I do not trust this man with my health.

Kind and informative
He is very personable and clearly explains conditions, treatments, and self care. He has called me at home to explain results and encourage me. He is very knowledgeable and shared information clear and concise in a down to earth manner.

Where do I begin, first I'll talk attitude, he has the "I'm a Dr my crud don't stink syndrome" and acts like you are clueless about YOUR OWN body. Second, because of this attitude he missed the fact that I had a bleeding ulcer and unconcerned of my cholecystitis which that later I had my gallbladder removed. He brushed my husband off as well all he told him is if meds didn't work stop taking them. Instead of trying to look into his issues further so we sought a second opinion who inadvertently found out he had kidney cancer and his stomach problems were real. He has inflammation of the small intestine which his new doc is doing more testing and trying different meds. Lastly I guess he didn't realize I know my stuff and I discovered he overcharged for his visits. They charged a level 5 E/M code for both of us. He did no review of history, one maybe 2 systems on the exam, and a Low to Mod decision making. He did not spend the time required in counseling of more than 50% .
