Dr. Katie Bullwinkel, D.M.D., M.S.

The art and design of a smile has been a passion of mine since I was 16 years old when Dr. John Pitner introduced me to the field of orthodontics.  I began working at his Columbia office after school while at Chapin High School and later during college and dental school summers.  Both he and Dr. Leslie Pitner have been mentors to me throughout my education and training.  I cannot be happier to join Dr. Leslie Pitner and the team at Pitner Orthodontics.

Background & Education

I grew up in Chapin, SC and attended Chapin High School.  After graduating in 2003, I attended Wofford College where I graduated magna cum laude with a B.S. in Biology, earning membership in Phi Beta Kappa honor society.  I earned my doctorate in dental medicine from the Medical University of South Carolina along with first graduate honors and selection to OKU, a dental honor society.  I then traveled to Chicago where I completed my orthodontic specialty residency and Master’s degree in Oral Science.  My thesis focused on aspects of positive psychology and its link to orthodontic treatment in adolescents.

I am the oldest of four Stroud kids, all products of the District Five school system.  My mom, Sally, still teaches reading at Chapin Elementary.  I am proud to be a part of the community that helped shape me and look forward to creating beautiful, lasting smiles amongst my friends and neighbors.  My husband, Matt Bullwinkel, and I are expecting our first child in December of 2015.  Our dog, Hudson, is very apprehensive and jealous of her upcoming status change.
