Sharon Lawton started Recreational Arts with Nathan Brewer in 2007. Sharon has a BA in Mathematics and an MS in Library Science. While she has enjoyed careers in training adults (computer programmers at AT&T) and pre-schoolers (13 years at Pluckemin Church Preschool), it is her volunteer opportunities which have given her the most joy. She spent more than 25 years with Rolling Hills Girl Scout Council serving in many positions from troop leader, to cookie manager, to President of the Board. For more than 15 years she managed the children and youth choirs at Liberty Corner Presbyterian Church, where she first collaborated with Nathan in 1999.
