    Brennan History and Legacy Employees

    We understand the value of adaptation, but we also recognize the importance of retaining who we have always been as a company: our values, our strong culture, and the way we do business remain the same. 

    Focused on quality since our inception in 1919, we take pride in its rich history and continued legacy over the next 100 years.
    We respect and appreciate all the people who helped build our company.
