Our Leadership

Kari Ann Kuntzelman
President

“Dental therapy is an essential part of improving the quality, accessibility, and cost-effectiveness of oral health care for all Americans. We can achieve oral health parity, but it will require policy change, state-by-state, clinic-by-clinic. Fortunately, ADTA here to help make this happen.”

Kari Ann Kuntzelman, Licensed Dental Therapist, shares her passion for oral health equity where she works as the Dental Health Aide Specialist at the Northwest Portland Area Indian Health Board – a tribal advisory board that serves the health policy and public health needs of the forty-three federally recognized Tribes of Oregon, Washington, and Idaho. As the ADTA President, Kari Ann aims to advance the practice of dental therapy as a means for ending oral health care disparities across the nation. Kari Ann is an enrolled member of the Chickasaw Nation and graduate of the Alaska Dental Therapy Education Program. 

Anna DeGraffenreid
Secretary

“The U.S. has so many underserved communities when it comes to oral health. Dental therapists can address these gaps. If given the opportunity, we can increase access to oral health care in a cost-effective way without compromising quality. It’s what we are trained to do.” 

Kylie Anderson
Director

“Dental therapy is about expanding access to dental services throughout our country and communities. Educating our patients on oral health and providing quality care, we are helping reduce oral health disparities.” 

Kylie Anderson, Dental Hygienist and Advanced Dental Therapist, is a practicing provider at Community Dental Care in Buffalo, Minnesota. She attended the University of Minnesota School of Dentistry, receiving a Bachelor's degree in Dental Hygiene and a Master's degree in Dental Therapy.

Claire Roesler
Director

“Something many people don’t know is that dental therapists provide cost-effective care. In fact, the reimbursement value of the care that dental therapists deliver often far exceeds the costs of their employment. This makes dental therapists a budget-friendly way clinics can expand their services and meet demand!”

Wilber Ramírez-Rodríguez

“When I provide care, each patient in my dental chair is treated the same. It is the way I would treat someone in my family; someone that I love. Because for me, everyone deserves the same quality and standard of care. And the purpose of Dental Therapy is not only to bring health care costs down, its purpose is to reach all who need dental care."
