Meet Dr. Sarah Fontana

Dr. Sarah Fontana grew up in Minnesota, where she earned her degree in Biology at the University of St. Thomas, in St. Paul, MN. During this time, she traveled both nationally and internationally on numerous medical mission trips, which ultimately led her toward pursuing dentistry. She went on to earn her Doctorate of Dental Surgery degree at the University of Minnesota School of Dentistry, graduating with honors in restorative dentistry. After receiving her degree, she worked in various private practices in Missouri while her husband, Dr. McAllister, was stationed at Fort Leonard Wood.

Dr. Fontana has completed a wide range of continuing education courses and specializes in aesthetic dentistry and prosthodontic services such as crowns and veneers. She enjoys working with patients of all ages and strives to create a relaxing and fun environment, knowing that going to the dentist can be difficult for many patients.

Outside the office, Dr. Fontana enjoys spending time outdoors, enjoying all that Montana has to offer. She’s a huge dog lover, and if you catch her running on the trails, you’ll probably see her with her two Boxers!

Meet Dr. Mark Colonna

Dr. Mark P. Colonna graduated from the Loyola University School of Dentistry in 1983. After receiving his degree, he stayed until 1992, holding the positions of Assistant Clinical Professor of Radiology and Assistant Clinical Professor of Operative Dentistry.

In 1991, he moved to Whitefish Montana and founded the Montana Center for Laser Dentistry. He began offering his patients the latest in minimally invasive dental care technology. A pioneer in the use of laser dentistry, Dr. Colonna is the first dentist in the world to use the laser technology to do many procedures without the use of drills or the need for local anesthesia in most cases. In addition, Dr. Colonna lectures and instructs on laser dentistry across the country and across the world. His articles on the topic appear in various well-known dental journals.

Dr. Colonna was awarded the “Inventor of the Year” for the invention of the PIPS™ technology, that uses the laser photons of energy to clean and completely remove biofilm from root canal systems by the World Congress of Minimally Invasive Dentistry (WCMID). He shares this award with his research partners from Arizona, with whom he also shares ownership in a number of patents related to laser dentistry.  In addition, from 2006-2010, Dr. Colonna served on the State of Montana’s Board of Dentistry Examiners. Dr. Colonna is an avid golfer, hiker, bowler, and loves doing everything in the company of his beautiful bride Susan and pup Bella.
