David Montgomery is the part-owner, general partner, president, and chief executive officer of the Philadelphia Phillies.
As a child, Montgomery attended Phillies games at Connie Mack Stadium. Before attending college, Montgomery worked as a diaper delivery boy and a high school baseball coach. As an undergraduate, Montgomery attended the University of Pennsylvania, where he was first a liberal arts major, and then a history major. Montgomery continued to attend Phillies games as a college student with future governor Ed Rendell, where he recalled " to eat all the food that $5 could buy... as they shared their thoughts with the players". He also attended the Wharton Business School as a graduate student, graduating in 1970. During his tenure at Wharton, he also coached the linemen for the varsity football team at Germantown Academy.
After interviewing for positions with Scott Paper and Quaker Oats and being encouraged by Rendell to apply for a job with the Philadelphia 76ers, Montgomery reached out to former Phillies ace Robin Roberts, whose son he coached at Germantown, about a job with the baseball club. Montgomery was hired as a member of the Phillies' sales department in 1971, becoming director of sales and marketing in the mid-1970s and the head of the business department by 1980. During the early 1970s, he was also the team's scoreboard operator.
