Our History

Dr. Schindler and his wife, Lynn, opened Schindler Family Dentistry in August of 1979 on the corner of 3rd & Boulevard.  Many of the people that came into the practice during those first 10 years, remain loyal patients today.

The practice then moved to Northbrook Mall for the next 15 years. In 2004, due to growth and the need to expand to add another doctor, Schindler Family Dentistry moved to its present location at 210 W Century Avenue.  In June of 2007, Dr. Katie Stewart joined the practice, and in January of 2010 she became a partner, and Schindler Family Dentistry became Schindler & Stewart Family Dentistry.

Dr. Steven Deisz joined Schindler & Stewart Family Dentistry in September of 2014 and became a partner of the practice April of 2019. He has been a great asset to this quickly growing dental practice.

Meet the Dentists

Katie Stewart, D.D.S.

Dr. Katie Stewart has always called Bismarck, ND home. She graduated from Bismarck High School in 1999 and continued on to the University of North Dakota. She received her Bachelors of Science Degree in 2003 and was accepted into the University of Minnesota School of Dentistry.

In 2007, Dr. Stewart graduated with a D.D.S and was delighted to move back to Bismarck and join Dr. Robert Schindler. Dr. Stewart is extremely passionate about dentistry and the patients she serves. In 2013 she was honored with the “New Dentist of the Year” award by the NDDA, and in 2015 was named one of the Bismarck Tribune’s “40 under 40” professionals.

In her free time, Dr. Stewart enjoys spending time with her wonderfully supportive husband, Nathan, and her three beautiful, but spunky daughters, Braelyn, Jaedyn and Ashtyn.

Steven Deisz, D.M.D.

Dr. Steve was born and raised in Bismarck and graduated from St. Mary’s Central High School in 2005. He attended the University of Mary in Bismarck, ND and received a B.S. in Biology in May of 2008. He then attended the Midwestern University College of Dental Medicine in Glendale, AZ and received his D.M.D. in May of 2014.

Dr. Steve enjoys the variety that general dentistry provides. He is eager to learn and constantly looking for CE courses to continue to grow his dental knowledge, having already completed a 300 hour course on dental implants before graduating dental school.

Dr. Steve is very excited to be back in his hometown where he enjoys the year-round outdoor activities North Dakota has to offer. He enjoys exercising, playing music, and spending time with his wife, Jill, and their two children, Benjamin and Madison.  They enjoy traveling to visit friends & family, or staying home with their dog, Kirby and cats, Joey & Stella.

Jordan York, D.D.S.

Dr. York was born and raised in Bismarck. He attended the University of Mary, graduating in 2011 summa cum laude majoring in Biology. He earned his dental degree in 2015 from the University of Colorado School of Dental Medicine.

After graduating from dental school he was eager to get back to North Dakota and all it has to offer. He grew up spending many hours on his family farm near Fessenden, ND and missed it. It was there that he learned what hard work was and also developed his love for the outdoors.  In his spare time he enjoys hanging out with family and friends, hunting and fishing with his dog Jax, and golfing.

His philosophy when it comes to dentistry is, “I’m here to educate you and come up with a plan that makes you happy!”  He enjoys all aspects of dentistry and working on patients of all ages. One of his passions is CAD/CAM dentistry.  He feels that having the ability to scan the teeth then design and deliver a permanent crown in one appointment is amazing. He believes the future of dentistry is exciting and is committed to staying on top of the latest trends and technology to ensure that you have the best experience possible.

Everyone was very professional and friendly, I really appreciated being treated so kindly. And my appointment was exactly on time, how refreshing. Can’t say enough good things about the staff, the dentist and the service. Dr. Deisz was very good about explaining everything, and did a great job on my broken tooth, and his assistant was so patient and kind. I will be recommending this clinic to my family and friends…….AWESOME!

I have been using Dr. Schindler and Dr. Stewart Family dentistry for over 25 years. My experiences have always been very good, no matter what I needed to have done from cleaning my teeth, to filling cavities and getting crowns!

Most people have terrible memories of going to the dentist, myself included. Each time I visit Schindler & Stewart Dentistry here in Bismarck, I am welcomed with a smiling face. The professionalism and honest approach and passion Dr. Katie Stewart has, makes me feel so comfortable when lying back in the awesome massage chair with a bright light shining down on me, mouth wide open…who else can make something like that feel “comfortable”. It’s been years since I have seen a dentist for the fear of unprofessional people with their hands in my mouth. I can promise you, I will never wait that long again thanks to Dr. Katie and her staff, you truly are amazing!!
