and was class salutatorian. He then attended Colby College in Maine and graduated with
distinction in Chemistry in 1989. After college he traveled Europe and visited 10 countries. He
worked for 2 years in Environmental Chemistry at Arthur D. Little in Cambridge, MA.
After spending some time in Evanston, IL, he would return to Cape Cod in 1993 to work
for many more years at Cape Cod Healthcare, both at Cape Cod and Falmouth Hospitals where
he enjoyed his everyday interactions with the variety of people he encountered in many
departments.
Will was a faithful Boston Red Sox and New England Patriots fan. He was an avid
reader and music lover. He enjoyed the outdoors with walks and bike rides. He was close to his
family, and was admired for his intellect, sharp wit and tremendous sense of humor. Will had a
generous spirit and was always happy to help others. His warm and caring personality will be
sadly missed by his family and all that knew him. Will often spoke of having gratitude and
finding meaning in day to day experiences, and the family asks that you would honor him in your
thoughts through these actions.
