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 Care You Could Ask For
I have had two Cervical Spine surgeries (anterior and posterior) performed by Dr. Onyiuke. He is a true professional, very caring and a tremendous surgeon. He makes sure you understand what he’s going to do and updates you after surgery. Truly an overall nice guy as well. Since he is highly requested, he does rely on his PA’s quite a bit - which can be disappointing when you want to ask him a question directly, but he also has the best PA’s working for him. I would highly recommend him to anyone with spine injuries. Best of the best.

Dr. Onyiuke did a 3 vertebrae cervical surgery on my neck 10 years ago. Never had a problem then nor since. He listened and discussed everything. He was terrific! Oh! I drove up from Myrtle Beach because I wanted the Best!

To begin, I have worked in the health care field my entire life and know the benefits of a referral, especially when it comes to our health and well being. I suffered from a 50% spinal chord impingement due to an accident, Dr Onyiuke was not only highly educated and proficient in his area of expertise but also detailed when it came to explaining my prognosis. I also appreciated is compassionate bedside manner. My 3 level cervical fusion (anterior cervical discectomy/ fusion) was completed in less than 2 hours. This is completely secondary but he also used a beautiful technique that left me with a very aesthetically pleasing scar that blended with my anatomy. I could not be happier with the results. I have and will forever recommend him and his team to my friends, clients and family.

Had back fusion surgery. This Dr and all of his team are the cream of the crop. They listen, they take the time to make you feel comfortable and explain everything thoroughly. I cannot say enough about them. If you have a condition that they can address, I highly recommend you see Dr Onyiuke. They are at the top of their game.
