Agatha Coon, RDH

Horizon Health Care is pleased to welcome Agatha Coon, hygienist, as a new provider at De Smet Community Health Center and Dental Services. She’ll be joining providers Devyn Prodoehl, DDS; Lamar Koistinen, DDS; Cindy Nelson, hygienist; and Devon Clubb, hygienist, in serving the De Smet community.

Originally from Martin, SD, Coon received her associate’s degree in science from the University of South Dakota in Vermillion. After living in Pierre for a time, Coon and her family missed the small town community and chose to move back to a rural lifestyle.

“I love learning about the human body and science,” said Coon. “I look forward to helping people who need care by sharing my knowledge and skills.”

Coon is married and has three children and a dog. In her free time, she enjoys camping and spending time with family. She is currently available for appointments at De Smet Community Health Center and Dental Services on Monday through Friday 7:30 a.m. to 6:00 p.m.
