Recently I've had to change dentist due to insurance. I was worried I wouldn't be able to find another dentist as good as the one I've had for years. The worry is over! Dr Marion and his Staff is Great! Believe it or not they make going to the dentist a pleasure. I hope their heads don't swell to much from this post but if they do that's okay they deserve the swelling. Thank You Dan Sr

This is absolutely the best dental experience I have ever had, everyone is super nice and caring - they went way out of their way to make sure I was comfortable and were so gracious about my anxiety - Dr Marion and his entire staff are wonderful they explain everything well and really take time to address any concerns I may have- if you are considering using them do not hesitate - I am an extremely nervous patient and for once am not worried about going back for more procedures- thank you to Dr Marion and all his staff!

Having a huge fear of dentists its been awhile since I've gone. Walking into Dr. Marion's office was immediately calming. Everyone was so nice and made me feel relaxed. They treated and talked to me like a human being. I will definitely return and not be so nervous next time around. I definitely recommend for anyone with a fear of dentists.

Marion smile is a fantastic dentist. I've been to multiple different dentists before and this is by far the best. The staff is always so nice and the dentist know what they're doing! In spring I knocked my tooth out of place and had to get a root canal. It wasn't painful for me at all. The back of my front tooth is nice and smooth. I am happy to recommend them to everyone I know.

I have been going here for years and Dr Marion is pleasant and thorough but each time I go it feels more like a used car lot. This is the second visit where I was given a service that was not covered by my insurance and was not asked before hand if I wanted it.

Outstanding Dentistry! Dr. Marion and his team provide excellent care. They are up to date on all the latest care techniques. All my experiences with the Marion Smile Center have been great. I wouldn't consider any other dentist for my dental care. I recommend the Marion Smile Center to anyone who wants top notch dental care.

This is by far the best dental office I have ever been to. The staff is friendly and professional and Dr. Marion is so gentle. I didn't even realize he had given me novacaine when I went for a filling. I recently took my 3 year old for her first visit. Everyone in the office went out of their way to make sure she had a great experience. She didn't want to leave!

I did not like being bombarded by staff taking videos to try to sell a bunch of cosmetic procedures. They then put all of your dental information on a postcard and mail for anybody to see. After complaining they stated they are changing their policies, but the damage has already been done. It should have never been a procedure in the first place. Violation of HIPPA Complaint has already filed with the health and Human services.
