Diane Dawson Dexter


After a long and distinguished career as a science teacher, and after holding other positions such as CEO, accountant, and stay-at-home Mom, Diane retired in 2001 to Fishers Island where she had been coming during summers for most of her life. While intending to focus on her painting, Diane immediately dove into island life serving in many capacities in the community. She was also very active at Union Chapel as moderator and deacon.  We are very blessed to have Diane as our organist on Sundays.

Diane is an accomplished singer, and has enjoyed horseback riding, competitive ballroom dancing, competitive swimming and diving, tennis, quilting, painting, gardening and reading. Most importantly, she strongly believes in the importance of family (she has three children, five grandchildren and a great granddaughter), education and volunteerism.
