Dr. Casper fixed a failed root canal and did a great job! He also stayed in contact with me checking in due to my infection and pain was really bad. Its great to know and see a Doctor care as much as he has. I am very grateful and impressed. I highly recommend Greater Endodontics in Riverton!

I had a root canal on Friday with Dr. Casper and it was so smooth on their end. I had so much anxiety but they were amazing and it went so quick! Literally the best!

The front desk staff was friendly, welcoming and helpful. Dr Larsen and his assistant Kelly were friendly and fun as well as incredibly competent and skilled. I was having a root canal from many many years ago retreated. The final x-ray was sent to my dentist and when I went in to have the access hole filled they told ...

I’m very grateful to Dr. Larsen, Kim, and the whole office. I had two difficult teeth that ended up needing root canals, including an emergency situation, and they took excellent care of me from start to finish. Dr. Larsen was extremely thorough and dedicated, and Kim was incredibly kind, helpful, and responsive duri...

I am so impressed with Dr Casper and his team who was able to see me the same day I called for a root canal that was well overdue. His communication skills are impeccable and he kept me in the loop during each step of the process. If every doctor, dentist or other provider was as on the ball like this office, it would ...

My experience was great. I had a couple little twinge pains but nothing really bad. The receptionists were very nice, Dr. Brimley was very nice, I liked him. Very good place for a root canal.

It's hard to say that a root canal was pain-free but with Dr Brimley that's true. His support staff was attentive and made sure I was comfortable during the procedure. Dr Brimley explain to me what was going to be done and checked periodically to make sure I was okay and comfortable. I love the application of new techn...

I was dreading having a root canal done, but Dr. Brimley and his assistant did an outstanding job. Dr. Brimley explained their procedure from start to finish, potential problems and what to expect. During the procedure, they continually monitored my status and ensured that I was comfortable. Other than experiencing s...

The Dr was so good I didn’t feel a thing. He was very punctual and his assistant was right there too. I hope I don’t need to go back but he’s my guy and I would tell EVERYONE to go to Greater Endo!!

I suggest a rebrand. I propose that the new name be GREATEST (in all of Utah, perhaps the world...hahaha), Endodontics Riverton. Don't let my effusive style make my words seem less sincere. I was worried, going in. I mean, I'm not tough like m0oms are. Even though my first root canal with these great people was so pain...

Great bedside manners

100% painless - even Novocain shot in back of jaw! Didn’t even know Dr Brimley was shooting me up. Zero pain or discomfort after the root canal. Incredible friendly and efficient staff. Dr. Brimley was awesome and did a fabulous job. My primary DDS told me the root canal would be very tricky but Dr Brimley did it wi...

The staff and assistants at Greater Endodontists were friendly and helpful. The waiting room and procedure rooms were comfortable and calming. Dr. Brimley explained to me what needed to be done and why it needed to be done. Dr. Brimley calmed my nerves and was very gentle. I did not experience any pain or discomfort ...

The highest professionalism, had a great experience there.
— James Sadler, Posted April 2nd 2026 on google
I have had 2 root canals and one retreated on a 3rd tooth done over the past year. All have been really great experiences. Dr. Brimley and his assistant were great. I love how thorough they are and even taking pictures before finishing just to make sure. Gives you that extra reassurance. All the staff have been amazing...

I had a wonderful experience at your office. Was comfortable and realized. Great staff!
— Vicki Southern, Posted March 31st 2026 on google
They were so friendly, gentle and understanding. They did a fabulous job on my root canal. The atmosphere felt like you were at home. I was able to take a nap and didn't feel anything with the gas and before I knew the procedure was done. I would recommend them for anyone who needs any type of procedure. They were AMAZ...
