Dr. Brimley is amazing. The entire staff was phenominal. They are friendly, knowledgeable and very thorough. Highly reccomend!— Robert Rasmussen, Posted August 28th 2026 on google
I dreaded going in for another root canal. Then Dr Casper started with the novacane . I never felt the needle, even the inside shot. This was the most pain free dental appointment in my entire life. This was my 5th root canal the 3rd on this tooth. Greater Endodontics gets my vote.— Craig Thompson, Posted August 28th 2026 on google
Friendly staff. Love Dr Brimley.— Penny Peterson, Posted August 26th 2026 on google
I had a good experience getting my first root canal. I was pretty nervous, but they calmed me down and the doctor and assistant worked well together and made sure I was okay. Highly recommend this office and staff.— Tina Hansen, Posted August 23rd 2026 on google
Absolutely incredible! I was literally shaking when I got in there but then once everything was done, they calmed me down and we’re so amazing @everything! And I didn’t even fill my shots. I was like wow he’s really good!!!— Katie M Garcia, Posted August 22nd 2026 on google
Dr Brimley took me right back and took care of a root canal that was giving me pain. I was extremely impressed with how he and his Assistant worked seamlessly together throughout the process. You could tell they have done this together for a long time. She knew exactly what he needed, and at just the right moment. They...— Brian Crook, Posted August 19th 2026 on google

Everyone was very friendly from the receptionist to the back office and doctor.— Melinda, Posted August 18th 2026 on google
I wish I could give this place more stars. If they were a general dentist, I would 100% be going to them all the time for my dental needs. They treat you with such care and compassion. It’s already hard for me to go to the dentist due to past things that have happened, but they definitely calmed down my anxiety and h...— Sophia Head, Posted August 15th 2026 on google

Excellent service. No pain.— Dave Johnson, Posted August 8th 2026 on google
I had a great experience this week getting a root canal. I know that’s not really a true statement. How could a root canal be a great experience? That said, my experience was great all things considered. I was well taken care of during the process. The front desk was friendly. Everything was communicated clearly. I ...— Jared Day, Posted August 6th 2026 on google

Dr. Casper and the team were so kind! Made my experience so much easier! Thank you!!— Marathon Momma, Posted August 1st 2026 on google
I had a root canal that had gone bad from years prior. Dr Brimley was amazing! Best shots ever! The office staff was great. Fortunately they were able to get me in on the same day.— Michelle Hathenbruck, Posted July 31st 2026 on google
Doctors in the Saint George area told me they could not save my tooth. Greater Endodontics Riverton was able to rescue and repair it. And they accepted my insurance. No ENDODONTISTS in the Saint George area will accept dental insurance. Something’s not right! Thank you to the entire staff!— utahsong, Posted July 31st 2026 on google
Dr. Brimley is sensitive to individual needs and extremely detailed in his work.— marilynne linford, Posted July 29th 2026 on google
