  • What Patients Say...


  • Dr. Trosien is an awesome orthodontist! He is a very knowledgeable and compassionate person. I have been his patient for a couple of years now, I wouldn't go anywhere else. His staff is just as compassionate and professional as he is."

  • Dr. Trosien is the best orthodontist! I wouldn't trust anybody else with my kids. My older son was born with an underbite. Dr. Trosien is doing his best to help him. Until the proper time for him to have jaw surgery. My younger son initially did not have enough room for his upper permanent teeth to come in. He currently wears braces. His permanent teeth are coming in nicely thanks to Dr. Trosien.
