Dr. Geck has put in 3 crowns for me and I love them; he also teaches at the dental school in town; very friendly and easy to talk to; I would highly recommend him.

Dr. Geck has done everything from cleanings to crowns, extraction etc. He's a very mild mannered person and has a lot of integrity, as well as being tructworthy and compassionate toward patients.

This was my first visit to Dr. Geck and it was great. He takes the time to know you and explains what he's doing. He makes it very relaxing. He has a very nice office and a great staff to assist him. You won't be disappointed.
