The proximity to the Canadian Rockies gave them unlimited access to hiking, skiing, and snowshoeing. From there, they moved to Paris, France which taught them valuable lessons in adaptability as they learned to live in and love the French urban culture. When they weren’t exploring the City of Lights, they spent their spare time touring around Europe. Their next move repatriated them to Jacksonville, Florida where they got to indulge their love of seafood and readjusted to the American way of life.
Their most recent move in 2016 brought them to Keller, Texas where they live with their beautiful Calico fur-baby, Sienna Vienna. They are enjoying exploring the great state of Texas and meeting new friends. The relationships they have developed in all their “homes” mean the world to them.
Sue and Bob joined the Trinity Presbyterian Church family in the fall of 2016 and Sue accepted the position of Director of Communications in October 2017 and is very excited to serve her church family in this capacity.
