He strives to further his dental practice through continued education and practicing the latest techniques to better serve his patients. Dr. Regenold takes great pride in ensuring every patient who walks into his practice is treated with care and compassion — an experienced dentist with a reputation for exceptional service and gentle, personalized care.
Dr. Regenold and his wife, Cassara, have six children, a son-in-law, and a granddaughter: Gracelynn, Jesse and Selah, Dylan, Abigail, Lilly, Carleigh, and Liam. He enjoys spending time with his family, woodworking, golfing, hiking, running, and all things sports-related.
Credentials
Family first
As a father of six, Dr. Regenold knows firsthand that many children feel nervous about visiting the dentist — especially if they've never been before. That's why he takes extra care with younger patients, completing treatment at their pace and making sure they leave with a smile.
The Regenolds live locally and are active in their community and church. If you run into them around Spring Hill, Columbia, or Franklin, say hi — chances are you already share a dentist.
