Dentistry is constantly changing and my goal is to remain current with this dynamic health profession, which is why I have become a member of the professional societies shown below. With the help of a strong educational background, and participation in local dental societies, I hope to provide the best possible treatment for my patients and promise to be conservative in my presentation of treatment options.

About Me

While away from the dental office, I have the privilege of spending time with my beautiful wife Kimberly and two wonderful children, Baylie and Kaleb. Together, we enjoy activities that include camping, boating, waterskiing, wakeboarding, golf, skiing and snowboarding.
