My name is Debby Coffey, I was born in Milwaukee, Wisconsin and moved to Grass Valley, California when I was 6 years old. I graduated from Nevada Union High School. After graduation I attended Sac City College and Sierra College. After starting a family I worked in the electronic industry for Grass Valley Group and Eigen Video. Having 3 small children I chose to work in the dental industry. I worked for Dr. Wayne Hood and Dr. Craig Zelenka in which turned out to be a life long career.
