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.

Great doc! He explained everything that others could not figure out. He's quiet,calm and patient. He took his time with me. I followed his post op instructions & it all worked out perfectly. I was able to limit my medications. Got me in & out of the hospital quickly. As a nursing professional, I have seen many neurosurgeons but I would highly recommend him to anyone.

I am so thankful for Dr . Dennis. I met him one night while I was admitted to the ER. He was able to diagnosis my problems & took time to explain everything. I was happy he believed in conservative surgery. We talked about it & agreed to use two operations, instead of one highly dangerous operation, (which is extremely expensive.) He is kind, extremely knowledgeable & always available by phone. He has changed my life & I appreciate him.

He is a very caring and listening doctor! He came to see my husband whilewhile in his care every day! I'm truly thankful!

Kim Comer in Richardson Texas – Jul 18, 2017

Admitted to hospital due to acute onset of 10/10 level back/leg pain. Came into my room at 3 am to give me the results of my MRI, but never examined me. Said that I should not be having as much pain as I was, but didn't bother to figure out why I was in so much pain. Ordered 7 different prescriptions for symptoms I did not have (kickbacks?) and said I should go to PT. I could not even sit up in bed without severe pain. Discharged me with 10/10 pain. Had to crawl into back of husbands car. Awful

I am very satisfied with Dr. Dennis. His patience in answering all of my questions was very satisfactory. Today, I had no prior appointment with him, but even then, he made time to see me. His overall treatment of me as a patient was excellent. I will always recommend other patients such as myself to him for treatment. I would like to thank Dr. Gary Dennis.

Dr. Dennis is an exceptional example of a true professional. He and his staff are top-notch!! Dr. Dennis listened and understood what I was going through. It was good to be treated with professionalism and care. Dr. Dennis and his nurse Stephanie and all the other employees of Frisco Spine Plano made me feel that I was in safe hands and even made me smile and laugh when I left. This was the best team of medical staff that I have been around in a very long time. Doctor Dennis is Awesome !!!

Dr Dennis is compassionate and kind and on top of all that, he's just a darn good doctor. I had a lot of scar tissue from previous back surgeries and he cleaned it all up. I'm only a week post surgery and I can already feel that I have no residual pain.

Pre-Surgery preparation, surgery and post surgery were excellent. Only negative is time management as waiting times in office to see him are sometimes excessive.

Dr. Dennis performed emergency surgery to control brain swelling after my wife suffered a major stroke . He acted very quickly and decisively, working well into the early hours of the morning and then returned to personally check on her first thing next morning and at least twice each day ( that I saw) next few days. I truly believe he saved her life, and put her in a position to have the best chances at recovery from the stroke. Thank you Dr Dennis!

Dr. Gary Dennis saved my life. I had two hematomas pushing on my spinal cord quickly making me a quadropelegic. Dr. Dennis operated from 1 AM to 6 AM to delicately perform a laminectomy. His bedside manner was wonderful. He checked on me more than any surgeon has ever done. When I go back for followups he spends as much time as needed, and never rushes me out the door. I highly recommend this man to everyone.

Had surgery to repair his 2 botched surgeries Dec 10 2015. Surgeon was able to fix all levels C4-7 all through the front of the neck with even a smaller incision than Dr Dennis done to start with . So my Back was split open for no reason just to get paid for a 2nd surgery! All muscles in the back are still messed up besides his failure to tell me about putting a screw out in open space seeing it on a CT and never telling me till I got a 2nd opinion!!
