Meet Our Doctors


Kelly Reynolds, DDS

As a locally-born and raised Montana girl, Dr. Reynolds feels right at home here in Red Lodge. The road here has given her time to develop into the style of doctor she is. All along though, the goal was to be able to care for a rural community of people and raise her family in that community. She truly enjoys what she does, which includes a broad spectrum of general dental treatment. Pediatrics, prevention and education, cosmetic dentistry, and denture and missing teeth cases are the areas she has the most interest in, but getting to know her patients is the basis of how she provides treatment. She hopes to create a true family practice, where people trust the environment and providers within it.
