I have been going to these guys for all my dental needs for 21 years now. Goodin and Martens are both very qualified, skilled, and friendly dentists (Goodin is also an orthodontist). They make kids feel at ease. Their office is a little hard to find, on the seventh floor of a medical building, but worth it! Their staff is helpful and will work with you if you need to come in for emergencies, and they are very friendly. I will never go anywhere else in Springfield.
