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.

We were early for our visit and Dr. Brennan was early for his appointment. He was very straightforward told us exactly what to expect and we definitely appreciated it.

No more leg pain!. Dr. Brennan did my surgery three months ago. He operated on my low back disc and I am finally free of that NASTY leg pain. His staff is awesome. Always called me back when they say they were. SO GLAD I called them. Thank you again. I am back at work and living life again.

Dr. Brennan and his assistant Stephanie were fantastic the whole way through. They both took time to answer any and all of my questions (and I had a lot) as well as helping to put my anxiety at rest during a few visits. I never felt like I was just a number on an assembly line. Each and every visit from my first to my last (3 months post-op) was treated like I was their only patient for the day. Even during the recovery while still in hospital, they and their team did an excellent job explaining everything to myself and my family. Anyone who’s had surgery knows you don’t remember much right out of anesthesia but they made sure to explain and prepare my spouse for what would be expected during recovery at home, which enabled him to educate me on what to expect once I was out of the drug stupor. I cannot recommend him enough!

We are so very lucky to have such a skilled neurosurgeon in our small town. I chose Dr Brennan to do both my neck and my back surgery. He is THAT good. He and his staff are excellent with pain management and after care.

I have my life back now! My son is happy his mom can play with him again and be active with him. Dr. Brennan is a God send! His staff is remarkable and always helpful. I could barely walk before surgery and now I am running again. My surgery went fantastic, I had very little pain, and my recovery was a piece of cake! I will forever be grateful to this man. He is exceptional. Thank you, Dr. Brennan.

Excellent !!! I can’t say enough about Dr Brennan. I took my husband to see him and could hardly walk. He had spinal cord compression. Dr Brennan explained everything to us and surgery was done that WEEK!. My husband is recuperating steadily and we cannot thank Dr B and his staff enough for giving us hope and doing a great job!

HORRIBLE!!! bedside manners, my 19 yr daughter was in a horrible wreck w/ 9 t- breaks, him & his NP saw my daughter in the ER and flipped through the CT scan so fast that she, him and the radiologist all missed that the T8 was completely broken all the way through. They released her off the back board saying she only had fractures and they would heal on their own. Thank goodness wk after wreck her leg went numb and I contacted a dr in New Orleans that ended up having to put Rods & Screws

Had a 3 level disk replacement and fusion in my neck. Dr. Brennan and his staff were very helpful. I believe the fact that he had the same surgery I had makes him more understanding of his patients needs and fears. Very satisfied with his work and if I ever need another surgery he is my first choice!

Dr. Brennan did a cervical fusion on my neck in 2010 and everything went great. He walked me through everything that would happen before, during, and, after the surgery and recovery period.When I learned that I had a bulging disk at L-3 affecting my sciatic nerve, he was the only surgeon I considered. I am 5 weeks post surgery and recovering well. His P.A.C. Lena is the best. She spends as much time as needed with you, answers your questions makes you feel at ease. They work very well together
