    About Mueller Security & Investigations

    In 1979, Leo Noe decided to channel his years of hard-earned knowledge and invaluable experience as the regional manager of a nationwide security company into the creation of his own security agency. Joining him was his son, Lee, also a veteran of the the security and investigations industry. Lee had been a point man on a roving unit specially formed to provide security at labor disputes throughout the Northeast.

    Within just one year, the fledgling company had secured three major contracts with businesses that, more than two decades later, still employ Mueller Security & Investigations for their protection. The firm is now Western New York’s largest locally owned security and investigations firm, with over 175 employees and an enviable record of service to area businesses.
