Meet the Dentists

Dr. Lisa Spier

Lisa Spier, DDS, D. ABDSM

Dr. Spier grew up in Brainerd, Minnesota, as the oldest of three siblings. She knew from an early age that she wanted to pursue a career in a health-related profession and began practicing dentistry in 1992.

After graduating from dental school, Dr. Spier began working for the State of Minnesota part time providing care for the developmentally disabled. She also worked part time in private practice in Farmington. In 2000, Dr. Spier took over Dental Care Associates of Buffalo.

Dr. Spier offers a full range of family dental services, including cosmetic, restorative, and orthodontic treatments, and is also a sleep dentistry specialist. Inspired by her own sleep apnea journey, Dr. Spier found a sleep appliance to be life-changing and couldn’t wait to offer oral appliance therapy to her patients so they, too, could sleep better and improve their health.

Outside of work, Dr. Spier’s interests range from early morning walks and amateur photography to scrapbooking and painting barn quilts. She is married to Ron, and they have two adult children.

Dr. Kellie Roseberg

Kellie Roseberg, DDS

Dr. Roseberg grew up in Willmar, Minnesota. Dentistry and orthodontics run in the family: She first became interested in a dental career because her father was an orthodontist and her godfather was a dentist. Inspired by their passion for the profession, she first obtained a bachelor’s degree in psychology and then completed her Doctor of Dental Surgery in 2005.

Known for her compassionate nature and gentle chairside manner, Dr. Roseberg takes the time to listen to each patient and care for them like they are a member of her own family. Dr. Roseberg enjoys continuing her education so she can provide the best possible care to her patients. She was also an annual volunteer at Team Smile and provided free dental services for underserved children.

Outside of the dental office, Dr. Roseberg loves spending time with her husband, Will, and her two elementary-age children, Hunter and Weston. They enjoy fishing, cross-country skiing, gardening, and family game nights.
