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.

I highly recommend Dr. Gray
I have been a patient with Dr Gray for over 10 years. He is an all around rock solid doctor. He knows his stuff. Is very thorough in explaining a situation and the recommended treatment plan. You never feel rushed. Bonus-round, he is a very likable individual. Bottom line, you can’t go wrong by choosing him as your doctor.

The best Dr I ever had.
Dr Gray was referred by another one of his patients some years ago. Best move I ever made and lucky to be one of his patients. He is very personable, non-judgemental and truly cares about his patients. He gives solid advice always and never rushes when it's your turn to see him. Keep up the great work Dr. Gray. You truly make a difference in your patient's lives.

I was part of this practice back in the 90’s. Dr. Snodgrass was my PCP until he retired from this practice. My care was transferred to Dr. Watson-Ficken. When she left the practice, my care was transferred to the NP, Gina instead of to Dr. Gray. I wrote a letter to Dr. Gray, telling him my history with the practice and my multiple health issues, and that my cardiologist thought I would be best served by an MD. I had no response of any kind to my letter. I have seen Gina for a couple of years, and she is lovely, but I want an MD. I asked recently if Dr. Gray was taking new patients, and the office manager, Terry, said,”Yes”. I asked if she would ask him if he would take me as a patient, based on my previous reasons. She went and asked him and returned saying, “He said no. He said, my cardiologist to call him if he had questions”. I am dumbfounded. I retired from nursing after 40 years and I feel that my needs are not heard in this practice. Won’t ask again. Time to move on.

Called today for a new patient appointment. Told it would be at least 10 months before I could see the doctor! I don’t think so! Not a patient friendly office!

Our 45 yr old son has struggled with alcoholism for many years. When he finally decided he needed help he saw Dr. Gray. Dr. Gray had a very long and frank talk with him and encouraged an inpatient treatment program. Whatever he said worked. He entered a program and 9 months later is still sober and working. My husband and I can never thank him enough. We truly feel he saved his life!

Needed basic annual exam. I had to wait 3 months for appointment. They called me a month before appointment stating they were cancelling and not rescheduling, dropping me as a patient because of a computer error. I asked if they could refer me to another doctor because I was needing a physical to continue Fostering children. They did not help and hung up on me. Now I'm scrambling.

Dr. Gray's staff doesn't answer the phone. They promise a response within 48 hours. Had to go to the office to talk to someone. All I wanted was a prescription refill. Sat for an hour after being asked to be seated while the "gate keeper" found someone who could talk to me. Ended up being told they would call me. Day 2 I was told I needed an appointment on a phone message. Day 3, called, got the voicemail again. Waited another 45 minutes in their office. Treated rudely by the doctor. Left!

I have been patient of Doctor Gray’s for years. I live in Florissant Mo and he moved to OFallon Mo. I will go where he goes no matter what! He takes time to listen to your concerns and he doesn’t make you feel rushed. I had blood work his office called me the next day regardless of test results. I referred several people to him and they all love him as well.

I love Dr. Gray. Have been seeing him for a number of years. Have followed him to 3 different offices. Every time he moves, I move. I have total trust and faith in him and his opinions. He takes all the time you need. Never rushes a visit. I highly recommend him for your doctor.

I have just become a new patient with Dr. Gray and have only seen him 2 times. So far, I have been happy with him. However, his staff is another question. They seem disorganized. They have taken over two weeks, several phone calls and a personal visit to send a referral (still not sent). The office staff and how they handle your needs is just as important as the doctors care. I know that with all the insurance hassles, etc they are overtaxed, but that's what they're job is.

He takes time with his patients, spends time working on one problem at a time and doesn't load you up with a bunch of medicine at a time so if you have a reaction you don't know which one caused it. Very good bedside manner.
