Norm Treinish goes into the Pennsylvania Lacrosse Hall of Fame as "a truly great coach who has contributed noteworthy service to the game of lacrosse over the years in Pennsylvania." Norm, or "Uncle Norm" as he is affectionately called by many of his current and former players, began his association with lacrosse as a player with the Cleveland Lacrosse Club in 1957 and 1958, but he really began to leave his mark on the game when he founded Ashbee Youth Lacrosse in 1974. Since then, he has served as coach and chief administrator of the Ashbee program, teaching boys the game he loves.

Norm was a co-founder of the Southeastern Pennsylvania Youth Lacrosse League (SEPYLA), the first organized league for boys programs in Eastern Pennsylvania. Norm served as SEPYLA Vice President in 1993 and as SEPYL President from 1994 to 1996. Since SEPYLA's inception, Norm's 7th & 8th grade Al Ashbee teams have won the SEPYLA Championship ten times. Over the years the Ashbee program, which now begins with 3rd graders, has developed many players along the Main Line, who have gone on to become All State and All American high school players, as well as collegiate All Americans, many of whom are known by nicknames given to them by Norm. At least three have gone on the play for the United States Men's National Team. In the past ten years, the Ashbee program has provided the opportunity for an average of 230 boys per year to play the game. More than that, he helped spark interest in the game and planted seeds throughout the area to foster the development of boys' youth lacrosse. In 1982, the Pennsylvania Scholastic Lacrosse Association selected Norm as its "Lacrosse Man of the Year."

His coaching career has also extended into the summer league, where for many years he coached the Lower Merion High School entry in the Southeastern Pennsylvania Summer Lacrosse League (SPSLL). In the late 1980s and early '90s, he coached teams in the Men's Division of the summer league, mostly consisting of former players that simply could not get enough of his wit, charm, enthusiasm and abiding love for the game - young man who played their high school lacrosse at Lower Merion, Harriton, Episcopal and Haverford. Many of these high school program owed their success over the years in part to players who learned to play lacrosse in the Ashbee program. His 1986 "Sporting Goods Place" team won the SPSLL Men's Division Championship; he also coached "Team Ritz," again consisting mainly of Ashbee alums and their chums.

Norm was one of he founders of the "Ralph Club," a group of fathers known for their conspicuous, unabashed but ultimately fun-loving displays of pride over the various and sundry accomplishments of their respective sons, typically as fixtures on the sidelines or in the stands at men's club games. Norm, a commercial artist who is also credited for designing the logo of the Philadelphia Wings that is still in use today, created the artwork that was given annually to the winner of the Ralph Award, named after Norm's friend Ralph Davy. The Ralph Club eventually evolved into the Philadelphia Lacrosse Association (PLA) in the mid-1980s. In 1988, Norm served as Vice President of the PLA. Norm was also a member of the Board of Directors of the original Philadelphia Wings indoor lacrosse team in 1974 and 1975.
