Later, he contributed to Harvard's Fogg Art Museum as a member of its Committee of Overseers. Stralem also engaged in postgraduate studies at Trinity College within the University of Cambridge.

As an influential figure in the travelers aid movement, Stralem served six years as president of the Travelers Aid Society of New York (TASNY) before taking on the role of vice president. He also presided over the National Travelers Aid Association and chaired its 1950 biennial convention.
