Meet Dr. Dan Kratzer – Orthodontist In Shawnee, Midwest City & Norman, OK
I was born and raised in Allentown, Pennsylvania. I am married to Kristin Kratzer, who is a general dentist. Kristin grew up in Green Bay, Wisconsin. We have 3 kids, Eliza, Luke, and Evan. My kids are young, but I can already tell they will all need braces. They are popcorn maniacs, and Luke really loves candy – so I’m no different than you when it comes to some of the future challenges of life with braces!

Orthodontist With A Passion For Orthodontics & Learning

I went to college and dental school in PA before moving to Oklahoma in 2008 to attend an orthodontic residency at the University of Oklahoma. After 11 years of school, my proudest academic achievement came in 2012, when I became board-certified by the American Board of Orthodontics, a designation that only 30% of orthodontic specialists achieve.

At OU, I met Dr. Behrmann and Dr. Kadioglu, who are the best partners anyone could ask for. Our common mission and vision for Orthodontic Specialists of Oklahoma is to improve the quality or orthodontic care and access to orthodontic care in the state of Oklahoma. We love what we do.

Outside The Orthodontics Office

My family and I love to travel, and our favorite place to relax is the Bahamas or the Mountains. I spend most of my free time playing with my kids, taking them fishing, going biking with them, and playing cards and other games. Luke is only 4, but he always tries to stack the deck when we play – but I’ve caught on to him! Recently we have been learning magic tricks and doing artwork. If I ever have any time to myself, I like to ride my bike or visit the YMCA.

5-Star Reviews

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.

My son started his braces journey last year June, and I couldn’t have chosen a better place for him to receive orthodontic treatment. The customer service is always great we’re always greeted with a smile, additional assistance, along with appointment reminders from Iromi and Ashley. They genuinely care about their patients, facility is always clean, awesome attention to detail regarding patient care. My son sees Dr. Kratzer and he literally is the BEST, coupled with his assistant Rilee she is just so great! We love her energy so much!!! If you’re looking for a place to start your orthodontic journey, look no further than here!
