Patients Love Us!


We’ve had a great experience at OSO:) we’ve had experience at another local orthodontist and this group is by far the best! From the front desk staff, to the assistant(?) to the doctor everyone has been so caring, friendly and supportive. Special shoutout to Dr. Kratzer and Zay, they are the best! Zay is so responsive to my daughter and is such a sweet soul. You can tell, they are just great people in general ❤️thanks for making this a great experience.

My son has been with oso for the last year and the switch from Dr Rainey to them was seamless! They took over and did an amazing job with his teeth. I am very pleased with the price, service and result! 10/10 would definitely recommend

I just recently got my braces off and absolutely loved my experience with OSO! They really care about your teeth and only want the best smile for you! Mckenna was great and always made me feel good when I sat in her chair! Also, Dr. Dan is the man!!!

This establishment is a shining example of excellence! The staff here are truly outstanding, taking the time to thoroughly explain everything I need to know and ensuring my daughter feels empowered and at ease. They consistently go above and beyond to verify that she has all necessary items to properly care for her braces. I’m so grateful we chose OSO Orthodontics MWC to transform my daughter’s smile!


Stephanie Christine


My daughter is a patient at OSO. I have been pleased with our experience and service. The staff is friendly and professional. Anytime my daughter has had an issue with her braces or retainer we were able to get in the same day.
