"Today was my first visit, and there is no doubt that I will go back. As a matter of fact, I have already scheduled my next appointment. The staff is very nice, the technicians are caring and gentle, and Dr. Marion was fantastic. I would highly recommend them to my family and friends."
"I made an appointment due to tooth pain that came out of nowhere. They got me in very quickly and did excellent yet gentle work! I am back again a month later for routine dental work and will continue to choose Marion Smile Center!"
"Marion Smile Center is great! Everyone is friendly, personable, caring, and professional. They really care about your dental health and will make specific suggestions, so you can improve your home care routine. Their hours can accommodate almost any schedule. I look forward to seeing them every 6 months – how often can you say that about dental checkups? "
"Marion Smile Center is amazing for the whole family. We’ve been taking our little one there since the age of 12 months, and we’ve never had a bad experience. They take the time to make sure kids feel 100% comfortable and have a positive experience. We are so grateful for such a caring practice!"
"I love Dr. Marion and his staff. They are caring, thoughtful, and always so nice. I have had lots of work done at the Marion Smile Center and never had any problems. Dr. Marion has a very calming demeanor and is very gentle. He always makes sure you know why he is doing any procedure. I can honestly say I look forward to going to the dentist, because I know I am getting the best care for my teeth. I highly recommend them, especially for anyone who really doesn’t like going to the dentist. Give them a try, and they will change your mind about dentistry."
"Wow! I’m so impressed with the entire experience. Everyone is so friendly and professional. The exam was so thorough, including in-depth photographs of problem teeth, a cancer screening, and so much more. Numerous issues were found that my prior dentist missed. I expected the visit to cost a fortune but was pleasantly surprised at the cost. I am extremely happy that I made the switch to Dr. Marion. "
"Dr. Marion and the staff are wonderful. My entire family has used this office for a decade, and we have been very happy. We’ve received numerous different services, including teeth cleanings, fillings, crowns, teeth whitening, and a veneer for a chipped front tooth. All services have been excellent."
"My daughter left our last dentist crying and Marion Smile has made her so comfortable every-time she is here. The staff is top notch. Highly recommended."
