Leslie Johnston Grayson, originally from New Haven, C.T., and now a landscape designer and living in Royersford, earned a total of eight varsity letters while at F&M as a member of the women's squash and tennis teams. In squash, Grayson was the number one player for the Diplomats and a participant at the national intercollegiate championships all four years. She served as captain two years and was named team MVP her senior year. She also joined coach Patricia Epps in teaching the sport to new players, and teaching then how to win.
As a sophomore, Grayson helped the Diplomats post the first winning record in the team's six-year history and placed 15th in the Howe Cup Tournament. Individually, she advanced to the fourth round of the consolation bracket before losing to a player from Middlebury. Grayson was ranked 16th in the country as a senior, and she led the Diplomats to another 7-4 overall record and a 5-1 record at the national team tournament. It was the first time the Diplomats posted two wins over Johns Hopkins in the same season.
She became the first F&M squash player, male or female, to earn first team All-American honors and finished with a 39-22 career record. Grayson was just as adept on the tennis courts. She was a four-year letterwinner in tennis and participated in the first NCAA Division III championships. In a story about the 8-1 tennis team qualifying for the national tournament in the College Reporter (4/29/82), writer Sue Ridge says, "Tell me what other coach makes sure there is licorice for Leslie Johnston '82, double stuff Oreo cookies, M&M's, fruit and granola bars for everyone on all the road trips."
