Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Root canal
I want to start by saying thank you Dr. Regan and his staff you guys are amazing. For 3 days I was in such miserable pain i couldn't sleep or eat. I was referred from my dentist and boy am I thankful for that. Dr. Regan is amazing, funny, and very professional. I was really nervous about the procedure since that was my first having root canal. Dr . Regan made me feel so comfortable that I forgot about the procedure, an hour and I was done I couldn't believe it. I highly recommend Dr. Regan and his staff. May God bless you all thank you so much.

Dr. Regan and his entire staff are great. Root canals are never fun but they make it as painless as possible. From scheduling to the actual procedure to the follow-up, it was all efficient and professional. Dr. Regan performed a root canal for me in 2021 and my experience was so good that I specifically sought him out when another tooth needed a similar procedure in 2024.

Nothing bad to say
I called the office at noon and got an appointment for 2 hours later. I was told I needed a root canal and was able to get it while I was there. Juanita, Dr Regan’s assistant, was fantastic and Dr. Regan was great. They make a great team! Explained everything in great detail and was very fast and efficient and I didn’t feel a thing! I highly recommend them!

Makes a root canal much easier
Making an appointment was very easy, even over the 4th of July holiday week. I have seen him before - He is always professional and helpful with all the advise he provides and the service that he preforms. Since the tooth was starting to abscess, it required to visits. After consultation with my dentist, he changed the course of action and simplified the follow up treatment.

Terrible Root Canal service
After Regan did a terrible Root canal on me he refused to refund 1/2 the $ 2000 fee promised and then wouldn't take my calls either. Never again. Use someone else if you want better treatment.

Dr. Regan and every member of his team were pleasant, professional, and competent. Dr. Regan is a clear and open communicator. He explained all of the images that he was using to make his assessment and then walked me through his diagnosis and recommended treatment. He listened well and clearly answered all my questions.

root canal was not good, and he refused to listen to my comments. He said he would reduce the fee from $1980, but never did.

I ended up having a complicated case which was not anticipated. Dr. Regan was wonderful! He took the time, did extra work in a very professional, calm, caring way. Dr. Regan and his assistant worked so well together. I feel really blessed to have had him as my dentist. I will definitely recommend him to anyone needing his services.

Experienced and efficient providers
I have had to undergo some rather extensive endodontic work over the last few years. My experience with this practice, particularly Dr. Witherspoon, has been excellent. They are friendly, professional and efficient; and the offices are spotless and organized. During treatment, I experienced very little discomfort. Additionally, this practice uses state of the art equipment that makes these procedures not only precise, but much more tolerable for their patients. Highly recommend.

Unexpected Root Canal
I went to see Dr. Regan hoping I had just a bad sinus infection...not the case! Dr. Regan had performed a previous root canal on me years ago & this recent experience was no different - GREAT (if you can say a root canal visit is great - HA!)! From the office staff, to his assistant, to him...all professional, kind and funny. Truly makes a "not so fun" visit, fun! Highly recommend this practice.

Phenomenal experience!!
I cannot say enough great thing about this practice..the staff and Dr. Regan. They squeezed me in due to horrible tooth pain, diagnosed that I needed a root canal and performed it immediately. Dr. Regan was a delight..funny and personable. The front office staff and dental assistants were so pleasant and very accommodating. Anyone needing an endodontist should look no further, this practice is phenomenal!!!
