2015 Game Changer: Sirmara Campbell Twohill

When Sirmara Campbell Twohill joined LaSalle Network as an office assistant, there was no HR department. More than a decade later, she is the chief human resources officer.

“Looking back, I realize how lucky I was that Sirmara walked into my office,” president and CEO Tom Gimbel wrote. “She has been instrumental in our growth.”

Twohill, 35, has lowered unemployment costs for LaSalle Network, saving the company an estimated $250,000. She has implemented a benefits package for all 2,000 temporary employees, which sets them apart from other staffing firms. Also adding an onboarding program, exit interview process, mentoring program and short-term disability insurance are just a few of her other major contributions to the company.
