Our Dental Providers

Dr. Giannelli loves her calling in dentistry. She began working with underserved children and felt and instant bond with community health. She believes that everyone experiences the need for help and kindness at some point in their lives, so she treats others as she wants to be treated. 

Dr. Giannelli received her DDS from Northwestern University Dental School (Chicago) and her BS from St. Mary's University in Winona, MN with a double-major in Biology and Psychology and a minor in Chemistry.

Open Door Health Center is a place with a soul, where all employees have the same mission --to foster nurturing quality care for all--which is what brought her from Chicago to Mankato in 2016 as Open Door's Dental Director.
