Sarah Maginnis joined NAIOP in 2018, previously part of the team at Liberty Property Trust for many years.
Since joining, our membership has more than doubled. She has implemented new programs and helped steer the creation of PREA, the Philadelphia Real Estate Alliance. She was at the helm during the pandemic, switching nearly seamlessly from in-person to online events, and when in-person became possible again, deftly switching back. She is proud to coordinate our summer program, and the chapter’s continued DEI and career development initiatives.
Sarah also testifies for NAIOP Greater Philadelphia in front of local and regional legislative bodies and organizes events and programs that impact and include people at all levels of the profession.
Always advocating the benefits of NAIOP Greater Philadelphia, Sarah can be reached at firstname.lastname@example.org or by calling 267-579-2901.
