Mary Richwine-Tumey

Hygienist

Mary Richwine-Tumey began her dental career in 1992 as a dental assistant - a role that sparked a lifelong passion for the field. In 2001, she earned her Associate of Science in Dental Hygiene from the Indiana University School of Dentistry (IUSD), followed by a Bachelor's Degree in Public Health in 2010. She later obtained her Local Anesthetic Certification Permit in 2017, also from IUSD. Just two days after graduating, Mary embraced another major milestone—becoming a mother. Balancing motherhood with her commitment to professional growth, she has remained dedicated to her childhood dream of becoming a dental hygienist. Today, she continues to inspire and empower the next generation of dental professionals through her work and mentorship. Mary has been happily married to her husband, James, since 2008. Together, they have three grown children—Kanon, Mallory, and Jessey. Now that their children are grown, Mary finds her greatest joy in being "Mimi" to her beautiful grandchildren, Sloane and Blaire.
