Sonja Johnson

Business Manager

”It’s so fun to see people stop having trouble with their teeth…”

Sonja lives in Fergus Falls and leads our administrative team. She grew up in Wendell, MN and attended Alexandria Technical College. She began her career in dentistry as a chairside dental assistant in 1989 and joined our team in 1994. You can count on her to greet you with a warm, sincere smile in person or over the phone. Her memory of names, families, and faces is extraordinary.

Sonja and her husband, Kurt, enjoy spending time with their son Joe and his wife Connie. Joe and Sonja study and teach at The Master’s Martial Arts Academy.
