I've been seeing Dr. Ryan and the team for about 3 years now, and since my first visit I've been so thankful for them. I was always afraid of going to the dentist due to experiences as a kid, but an issue with a filling a few years back landed me at Great Plains Dental and now I actually look forward to my semi-annual visits due to how much care the entire team puts into making sure their patients are well taken care of and feel comfortable. Today marked my son's first ever dentist appointment, and Dr. Ryan was amazing at making sure he felt safe, comfortable, and that his needs were taken care of. He's already asking me when he gets to visit "the tooth doctor" again. I'm beyond grateful for this team, and my family and I plan to continue coming to Great Plains Dental for many years to come.

This dental facility can't even bother to call it's patients before sending them to collections. Over $7. They also don't give a rats ass if you've fallen on hard times and will continue to add on late fees, turning a $7 bill into $20+. Don't use them unless you're not living paycheck to paycheck. Honestly, if you can't be bothered to charge patients in office at the time of visit for something as stupid as a toothbrush, you shouldn't even bother charging them 2 weeks after to begin with.

I am a new patient. They took care of my insurance issues and explained my next steps well. I was greeted immediately, the lobby and patient areas were clean and organized with tvs to watch, my cleaning was thorough but gentle, the dentist took time to know me and they sent me home with all the goodies including whitening strips. I will definitely be back!!
