Joy has been with MASON since 2002.

Joy knows that sustainability starts with preservation and adaptive use of our existing building stock. She enjoys researching a building’s history and examining existing conditions to create updated solutions; allowing the building to remain a vital part of its evolving community. She focuses on preservation plans, design guidelines, and historic structures reports for both residential and non-residential historic buildings, especially the unique building types on military installations. 

Joy believes that buildings have personalities, they can be old and cranky or have a sense of humor, but they all have stories to be shared.
