Katzman has been a cornerstone of the baseball program at John Burroughs High School since 1989 as both a head and assistant coach. During those 37 years, he has over 500 wins with three state championships, seven Final Four appearances, and eleven conference championships. Katzman was the assistant baseball coach from 1989 to 2000, and the Burroughs Bombers won the Missouri state championship in 1991. He became head coach in 2001 and the next year he guided the Bombers to the state championship. He was named Missouri Coach of the Year in 2002. He was head coach for 18 years until 2019. He has been the assistant baseball coach at John Burroughs since 2020. The Bombers won the state championship in 2023.

Katzman attended John Burroughs High School from 1981 to 1985, and he was a left-handed pitcher on the Bombers squad all four years. In 1985, he was the winning pitcher when the Bombers defeated Licking High School to win the
Missouri state championship. 

Katzman has been part of all four state championship victories in the history of baseball at John Burroughs High School. For over five decades, Katzman has been “Mr. John Burroughs Baseball” and last year the main baseball field at John Burroughs High School was renamed Katzman Park. 

In 1985 and 1986, Katzman was a pitcher for Wake Forest University in Winston-Salem North Carolina. In 1987 and 1988, he pitched for St. Louis University where he graduated with a degree in political science.

A consummate role model, he has positively influenced hundreds of young men to be better ballplayers
and even better human beings.
