These Dentists Carry On the SVDG Tradition

At Spring Valley Dental Group, our doctors combine decades of experience with a genuine commitment to helping patients feel comfortable and confident about their dental health. Each dentist brings a distinct perspective and skill set, but all share one guiding philosophy: do what’s best for the patient, every time.

Our team proudly cares for generations of families from O’Fallon and communities throughout St. Clair and Madison Counties, including Shiloh, Belleville, Fairview Heights, Swansea, Mascoutah, Lebanon, New Baden, Troy, Collinsville, and the Scott Air Force Base community. Together, our dentists continue a tradition of local, ethical, and compassionate care that began in 1974.
