Patients Love Us!


Dr. Kadioglu is so amazing. We moved here from Salem, Oregon, where we loved our orthodontist. He recommended Dr K, as he knew him from conducting conferences at OU. Dr K and OSO Orthodontics use the latest methods of orthodontia. The staff is amazing. The techs are patient and gentle with my son, who has Autism. The office staff are super friendly. We feel so fortunate to have them all!

As an adult who decided to have Invisalign, I looked at a few places before I committed to OSO. The staff is kind and overly communicative. The providers are approachable and “picky” for perfection. I have had use of the aligners without issue and have been pleased with my treatment.

I’ve had my braces on for 5+ years before switching to OSO Edmond. I’ve had major gaps in my teeth from my previous ortho not being able to do their job properly. OSO promised to have those gaps closed in less than a year. I am here today, less than a year later getting my braces off and showing me they kept their promise. Hats off to them for showing what real customer service, truth and great quality really is.Thank you OSO for completing the remainder of my time in braces. I recommend this place to anyone who is wanting braces or wanting to switch over.
