MARK ENDERS

MARK ENDERS, Human Resources

Hello, my name is Mark Enders. I am a recent graduate from the University of Wisconsin – Whitewater, where I gained my bachelor's in business administration. Before that, I graduated from Mount Horeb High School.

I pursued a career in Human Resources after really connecting with the subject in my studies. I originally started my education in Accounting, however I found myself wanting to work more with people rather than with numbers. I love being able to come to work and meet hundreds of qualified candidates in interviews and subsequently get to know each individual on a personal level. I then relish the opportunity to use that relationship to guide them into a successful career in security.
