Our Story

Montana Dental SPA opened in September of 2019.  With the help of a Dream Team of providers, Dr. Greg Seaman has created a unique dental practice which provides high quality dental care and promotes oral health in a spa-like environment. Our practice is designed to eliminate patient stress, anxiety, and apprehension.  Our Vision is to grow into the premier dental center in the Flathead Valley. We are committed to investing in and remaining current with developments in dental techniques, technology and offering the most scientifically proven treatments to our patients. We strive to develop life-long relationships with you and future generations of your family. 

Though dental care as our primary concern, our office also offers complimentary herbal tea, coffee, sound-canceling headphones to stream your favorite media, or a warm paraffin hand treatment to aid in providing the most relaxing atmosphere possible.  Your comfort and satisfaction is our focus along with providing the most comprehensive yet conservative care.

We are proud to welcome you to Montana Dental Spa and hope to see you in our clinic and spa center soon!
