Meet Dr. Marshall T. Lavin

"You can call me, Marshall." - Dr. Lavin

Originally from Vermillion, SD, Dr. Marshall T. Lavin is your caring, gentle, and experienced endodontist in Sioux Falls, SD… opens in a new window to Google Maps…. He is happily married to his wife, Angeline, and is the proud father of two beautiful daughters.

Dr. Lavin began his journey into dentistry when he had his wisdom teeth removed by Dr. Al Akerson. This renowned oral surgeon did everything in his power to talk Dr. Lavin out of becoming a doctor and into becoming a dentist – and he succeeded!

Marcia - Dental Assistant

I currently reside just outside of my hometown, Tea, SD. My husband, James, and I traveled for ten years during James’ military career and spent six of those years overseas. We moved back to the area to raise our children and our daughter still lives close by.

I never dreamed I would be working in dentistry; however, a fun conversation with Dr. Lavin led me to explore this option. 16 years later, I’m so glad I did!

I genuinely enjoy meeting new people and hearing their stories because they teach me something new every day. Through kind words and a kind smile, I try to make you feel at ease while providing you with a positive and unique root canal experience.

Dr. Lavin is nothing but professional and very pleasant to speak to. They have a very nice facility, and all the employees were super friendly. Dr. Lavin and his assistant were a hoot and kept a very fun conversation while executing the painless repair of a root canal that needed to be redone. If you need work done on your teeth in Sioux Falls, Dr. Lavin is the guy to go to. Thank you. 10 out of 5 stars if I could!
