About Us

At JT Dental, our philosophy is simple: treat our patients the way we would want to be treated. That means creating a safe, welcoming environment. It means working with a compassionate, experienced and dedicated staff. It means honest and straightforward communication. It means informing our patients and working with them to find the right solution.

These things were true when the practice was founded by Dr. Chroust in 1986. They were true when Dr. Thimjon (shown) took over in 2021. And they will be true tomorrow. And while going to the dentist may never be “fun,” we know it can be a positive experience. Hey, you may even look forward to it.

I have been with the practice since 2020. The part I like most about this office is getting to know the patients. Outside of work I like to spend time with my two kids, going on walks with our dog Sarina and being a member of my book club.

I have been a hygienist for over 35 years and love helping people achieve the perfect smile. In my free time, I love spending time with my husband Don, three daughters and a son-in-law. I also love sleeping in, reading a good book, going for a walk and working on my newest quilt creation! I love to travel and enjoy the peace and quiet of the Boundary Waters, but it is my dream to one day visit the Holy Lands.

As a licensed dental assistant, I have enjoyed helping restore smiles for 35+ years, 28 of them here in Rosemount. Moving into my new role as OSHA manager, I will continue to strive for the highest standard for our great patients and team. When not reading dental journals, I love gardening, fishing, playing with my chickens and catching up with our 3 adult children.

A message from Dr. Chroust

I am writing to you today to let you know that I have sold the practice to Dr. Jason Thimjon and I am transitioning to a part time status at the dental clinic. I continue to love dentistry, however believe the time has come for me to explore a new chapter in life.

The trust and confidence you have shown in me these past 35 years has been a blessing, and has been greatly appreciated. You have entrusted to me a great gift; the care of your friends, your family and yourselves. For that I am truly grateful. For this reason, I have taken the selection of my successor very seriously.

Dr. Jason Thimjon was a student of mine ten years ago at the University of Minnesota Dental School. He was an excellent student. I believe he is an excellent dentist and just as importantly a good person. We have had many long discussions about patient care and the importance of developing long term relationships with the people who trust us with their dental care. I believe Dr. Thimjon and I have similar views in this regard.

Throughout my career I have been blessed with loyal and trustworthy staff. I never had to ask for excellence, they consistently gave it. You will continue to see the same experienced and dedicated staff and will receive the same devoted attention from each staff member. I have been truly fortunate to have worked with staff members who have made my work life so enjoyable. I look forward to continuing to work with them on a part-time basis and will continue to teach as an adjunct faculty member at the University of Minnesota Dental School.

To all of my patients, I wish to convey my sincerest thanks for your trust, confidence and friendship these many years. I look forward to seeing you, speaking with you and introducing you to Dr. Thimjon over the coming months during this transition period.

Sincerely,

— Kurt P. Chroust, D.D.S.
