    Want me to list all of the things I love about how amazing Park City Orthodontics is? Dr Sumsion is cool, down to earth, efficient, and the nicest guy ever. He knows how to interview and train his staff to emulate how awesome he is. They are all friendly, happy, and insure you have a good experience EVERY time you go. The office is clean, inviting, and comfortable. My husband and I both have braces currently and one of the things I love most is that most, if not all of the staff have had braces. They are empathetic in how they work in your mouth. You guys, they have a free consult. If you want to see for yourself how awesome they are, schedule one now!!!

    Dr. Sumssion is the best orthodontist. He makes my visits fun because I get to play in his upstairs room & write my name on the wall & he's always happy. Its never painful either & all the teeth he does come out looking amazing. - Stevie 9 years old

    Your place it just the best! I love the board you have that says if you a new patient or if your getting your braces on or off! The people at the front desk are so helpful! The people working on your mouth are just so gentle! Really kid friendly! I just wish they had more colors for your braces. But really out standing all over!

I love being an orthodontist. Like winning the Lottery, orthodontics has opened the world to me and my family. There is extreme satisfaction in seeing new smiles, better self confidence and lives change. I often get asked: “What would I do if this was my child or my mouth?” With this in mind, I treat each individual case as if I were treating my own son, daughter, or wife. Here at Park City Orthodontics, my team and I have the same goal in mind: to provide excellent care to each and every one of our patients and make them feel like family. I have been part of the Park City and surrounding communities practicing orthodontics since 1993.


I am a native of Utah, and was raised in Bountiful, just 45 minutes North of Park City. I received undergraduate education at Brigham Young University, where I also competed on the Ski Team. I continued on to spend fours years at dental school at Oregon Health Sciences University where I earned my Doctor of Medical Dentistry (DMD) degree. After dental school I completed an additional year of training at the University of Utah in their hospital residency program. I then received my Master of Science and Specialist Certificate in Orthodontics (a two year program) at St. Louis University.

I attend many more continuing education classes than required by the state. We are always learning to successfully use the latest technology, including Damon Braces,Insignia custom braces, Invisalign, mini-screws and lasers. I am also a member of Wasatch Orthodontic Study Club and the Utah Damon Study Club. These classes help our patients receive the best treatment with results in the shortest amount of time.


Outside the Office

sumsion_familyI live here in Park City, with my wife Kristen (we just celebrated our 29th wedding anniversary). We have four children. Alexis graduated from NYU (yea!) and lives in NYC, Chloe is a dancer and will finish her last yeat at BYU, Ben graduated from Park City High and is serving an LDS Spanish Speaking Mission in New Jersey, will attend BYU in the fall and plays soccer. Sam is a Junior at Park City HS and plays tennis.

sumsion_bikeEven though my ski racing career ended, I still love to ski, but my true passion has been cycling. I enjoy both road and mountain biking. I started bike racing in 1984 to keep me in shape for ski racing during the Summer months, and fell in love with the sport. My “passing phase” in cycling has lasted more than 30 years. I still actively compete, and my bike has taken me all over the world. I also skate ski, attend my children’s activities, and travel with my family.
