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.

Best Doctor
I love Dr Greenwell. He is the best Dr and person I have ever met. He treats me so good and has patience with me. He will figure out all your problems. Carrie Wigley

Office staff is horrible
Dr. Greenwell is fine, but you can't see him. We were to have tests done by Feb. 25 and see him the next week. Called office 4 times and each time they assured me we were on the 'call back' list and would be seen by the end of March. Called April 19 when I still had not heard from them. " Sorry. We could only see 12 people. How about May 10?" To have tests done in February and not reported on until May is ridiculous. Finding another nephrologist.

DR Greenwell has changed my life after years of having a very rare Kidney disease with little help from others. After a few years of urine and blood tests quarterly we have got my numbers on track and keeping me fairly stone free. It’s not a cheap or nice thing to deal with but he has made it the best it can be under the circumstances. I would recommend any one needing a DR of medicine for the Kidneys.

Dr Greenwell is a consummate professional, genuinely concerned about his patient. He is caring, very respectful, and listens to, as well as informs his patient. I was referred to him but would have chosen him given the choice. I felt like a friend from the time we first met. I thank God for my good fortune.
