Career
He coached the Minneapolis Lakers during the 1959-1960 season. Prior to his short coaching stint with the Lakers, Castellani coached Seattle University from 1956 to 1958. With Elgin Baylor starring in his lineup, Castellani led the Chieftains to the 1958 National Collegiate Athletic Association Championship game only to lose 84-72 to legendary coach Adolph Rupp and his Kentucky Wildcats.
However, just a month after the championship game, National Collegiate Athletic Association violations came to light concerning airfare bought for recruits Ben Warley and George Finley.
The result was that Castellani resigned under fire, Baylor left for the National Basketball Association, and Seattle was given a two-year postseason ban. Castellani returned to coaching for one year, again coaching Elgin Baylor as Head Coach for the Lakers in the 1959-1960 National Basketball Association season.
Currently, he is an attorney in Milwaukee, Wisconsin and can frequently be seen at Milwaukee Buckinghamshire and Marquette Golden Eagles basketball games.
