[4] Fireman began his career at age 18 working in the family business, Boston Camping, selling outdoor sporting goods and fishing tackle for 15 years.

[2] While attending a sporting goods show in Chicago in 1979 Fireman met Joe Foster, the owner of an English running shoe company founded in 1958 called Reebok.

[5] Fireman acquired the North American sales rights to Reebok in 1979 and eventually bought the English-based parent company outright in 1984.

Riding the success of the Freestyle shoe as the aerobics craze swept across America, Fireman grew the company and Reebok issued an IPO in 1985.

[13][14] In 2017 Fireman spearheaded a push to expand the golf club by 3 holes by acquiring the Caven Point section of Liberty State Park, which is a migratory bird habitat, sparking a controversy amongst Jersey City community members and environmental activists.

[19] Fireman reportedly responded to the public backlash with a strategy to begin "framing the park’s redevelopment as a 'fight for social justice,' just as the nation was roiled by the police killing of George Floyd".

[20][21] The golf club also came under fire for collecting $751,452 from the Paycheck Protection Program, a relief fund for small businesses affected by the shutdown caused by the COVID-19 pandemic.

Fireman is a supporter of The First Tee whose mission is to "impact the lives of young people by providing educational programs that build character, instill life-enhancing values and promote healthy habits through the game of golf.
