He joined the Byron Dental Group in 1979.

Dr. Doug Trebtoske has made two mission dentistry trips to Guatamala. On one trip, all of his gear was carried over a wire supported swinging bridge into a jungle village. Once there, while sitting a a plastic stool, holding a flashlight in his mouth, he extracted teeth. Patients spat in a bucket to give him a clear field of vision to do his work. People lined up and watched for eight hours until he said he could not do any more.

He has 3 daughters Annie, a dentist in St. Cloud, Christine, a Palates Instructor in Hunting Beach, California and Elizabeth who lives in Des Moines, Iowa.

Administrative Staff

  • "Just wanted to say thanks for making our appointment scheduling so easy!
    Our entire family was able to be seen with only one visit. We appreciate your consideration."
    The Millers - Rochester, MN

  • “I had to find a new dentist in 1977. I elected to try the new Byron Dental Group, which had just opened. I’ve been going there for 30 years and I sure made the right choice. The staff is excellent; they use up-to-date equipment and resources, all generating a more personal touch.”
    Thomas T. - Rochester, MN

  • “I was a patient at the Byron Dental Group for over 20 years. A career change brought me to Texas. My new dentist told me I needed several thousands-of-dollars’ worth of work. I called and scheduled an appointment at the Byron Dental Group while returning for the holidays. Their second opinion revealed no such work was needed. I really appreciate their honesty.”
