After that, she continued her training at the University of Illinois at Chicago where she was awarded a Masters of Oral Sciences degree and a Certificate in Orthodontics. Dr. Bartels’ masters thesis studied the effect of soft drinks on enamel sealed with orthodontic primers.

She believes this will be reflected in their lives as adults, and provide them power in challenging situations.

“I LOVE my job. I love helping patients and families achieve their dream smile. The transformation of my patients as they gain confidence and a new outlook on life brings me so much joy. Seeing a person’s inner self change to match the change on the outside is the best reward for a job well done.”

“I'd contemplated braces my entire adult life. The last photo I had of me smiling was when I was 17 years old. I had so many fears and reservations. Thanks to Apple Tree, and their incredible staff, I can finally smile again! My only regret was waiting so long. Smiling again at age 44.”
