Ms. Gallagher worked in Project Management with her fellow founder James Snyder at the SmithKline and French laboratories in Philadelphia, Pennsylvania, USA. She participated in the 1969 meeting, in Atlanta, Georgia, USA, in which the five original founders and one more trusted person were looking to give a structure to PMI, and where they named themselves in order to cover several positions at the brand new organization. She served as treasurer, vice president of technical services, and director, and presented articles in annual meetings. Along with her fellow founders, Ms. Gallagher’s goal was to bring people from every field of the project management profession together, to learn, share and advance the profession. After she moved to Chicago, Illinois, USA, Ms. Gallagher participated in the PMI Midwest Chapter and played an essential role in the conception of PMI Seminars and Symposiums in 1977.
