Dr. Chris is a Board Certified Diplomate of the American Board of Pediatric Dentistry and a member in good standing of the American Academy of Pediatric Dentistry.  He can hardly believe he has found a profession he is more excited about than his dream to become a professional soccer player or musician.  He enjoys spending time with his wife Shelley, family, and friends.  On the weekends you can find him playing music, watching his favorite soccer teams (Arsenal and Barcelona), or out water skiing!
