 Dr. Craig Sommer of Springs Dentists. Before becoming a dentist, I went to the Colorado School of Mines and graduated with an engineering degree. I love figuring things out, but as an engineer, I didn't get to apply that to helping people every day like I do as a dentist. Now I use my problem-solving skills to help people live healthier, happier lives. Find out more about holistic dentistry, mercury-free dentistry, and more at springsdentists.com.
