About Dr. Rainville

Dr. Rainville was born and raised in a small town located in Southwestern Montana. With the beautiful Rocky Mountains surrounding the ranching and logging community of Deer Lodge, Dr. Rainville developed --- early on --- a love for the outdoors. When he is not seeing patients, he enjoys hiking, biking, tending to his yard, and downhill alpine skiing. He and his wife have raised their son here in Rochester along with their energetic miniature schnauzer, Ollie.

Dr. Rainville credits his upbringing in a small town environment for the enjoyment he derives from being helpful for those around him as well as for his commitment to giving back to his community. He is an active member of Rochester’s Rotary Club which improves the lives of people both locally and globally through volunteer-based service initiatives. Dr. Rainville is also active in his church and has served on the executive board of local non-profit organizations. At his core, he is genuine, humorous, engaging, and light-hearted yet meticulously focused for providing the utmost of precise, accurate, efficient results for his patients paired with conscientiousness, kindness, and warm hospitality.

Dr. Rainville recognizes the intrinsic value of remaining professionally and personally enriched through education. He graduated with honors from Montana State University-Bozeman with a Bachelors Degree in Biomedical Sciences and went on to complete his professional training at the University of Minnesota-Twin Cities. Thereafter, he applied to and completed a competitive hospital-based General Practice Residency through the University of Minnesota Hospitals. He has held staff appointments at Regions Medical Center in St. Paul, Anoka Metro Regional Treatment Center in Anoka, and the University of Minnesota Hospitals. He has been a clinical instructor at the University of Minnesota School of Dentistry and at Rochester Community and Technical College. He and his family have resided here in Rochester since 1989. He maintains an active commitment to participating in high quality continuing dental education by attending the highly regarded L.D. Pankey Institute, Pride Dental Institute, the Dawson Institute, and the University of Minnesota.

"I have personally assembled a consistent, long-term support team of professionals who are experienced, knowledgeable, and conscientiously focused on providing our patients with an unparalleled degree of calm professionalism, warmth, dignity, and peace of mind for their dental treatment. I genuinely appreciate the trust my patients place in me as well as in my support team...and together, we are committed to doing all we can to merit such a precious privilege."
