Always great service! They are very accommodating when scheduling appointments. Dr.Koester is very thorough, he explains every procedure before and while he's doing it. The dental hygienist also did a great job with my cleaning. I've never had any pain during any of my procedures. I would recommend the Dental Group of Carbondale to anyone who is in need of a dentist.

I love this place! I went to a dentist in Marion who tried to tell me I needed a crown and a root canal and all sorts of things after taking X-rays. I went to Dental Group of Carbondale for a second opinion, and asked the Marion dentist to send them my X-rays. After asking three times for them to be sent over, I go to my appointment and find out they’re completely illegible. Dental Group of Carbondale redid my X-rays at no cost to me and explained that while one tooth did need a large filling, I did NOT need a root canal or crown or anything like that. I’ve been going to the Dental Group of Carbondale ever since and they’re still just as great!
