Vanessa Woodworth, RDH, BSDH

Thank you for taking the time to view my biography and welcome to High Country Dental. I am a Colorado native, growing up a mere six miles away from High Country Dental, attending grammar, middle and high school locally. I am happy to be married and blessed to have two beautiful girls which always make life interesting. I started my first job in a dental office after school and it remains my passion today. I acquired my RDH (Registered Dental Hygienist) and BSDH (Bachelor of Science Dental Hygiene) from the University of Colorado: School of Dentistry in 2002. My most notable academic accomplishment was being selected for a seven day dental relief mission for the rural communities of Vera Cruz, Mexico; giving much needed dental support. My affiliations include American Dental Hygienists' Association (ADHA). I hope to see you soon here at High Country Dental.
