About Gary
The Williamsons continue to practice real estate sales with Cassie Mason Real Estate and they independently own and operate Four Seasons Vacation Rentals which serves the greater Sunday River area.
When they are not in the office, Gary and Julia are likely on the baseball field, at their camp on North Pond, or enjoying dinner (likely venison) with their four sons, one daughter-in-law, and granddaughter, Gracie. Grandparenting has been a life-changing blessing for Gary and Julia since Gracie’s arrival in 2021.
