I have been with Dr. Greenberg and RxSmile from his opening day in 1988! My job is to oversee the day-to-day functions of the office. I enjoy visiting with the parents and patients at their visits and getting to know more about each individual. I have two wonderful adult children. In my spare time I enjoy thrift shopping and spending time with my family and friends.
