Our Management Team

Christy Beiermann

Director of Talent Management / HR

Christy started at CSE in 1998 as a support analyst in the Help Desk department. She works hard to guard and guide the culture of CSE, turns the lights on in the office every morning, and puts up with a lot of childish antics from the development team.

Andy Grabenstetter

Director of Software Development

Andy began his career at CSE in 2005 as a Quality Assurance analyst. With unmatched attention to detail and valuable insight, Andy knows just about everything there is to know about every project at CSE. He oversees a portion of the software development team. Some may say his beard goes too far. We disagree.

Andrea Lusher

Director of Project Management & Support Services

Andrea started at CSE in 2003 as a support analyst in the Help Desk department. She currently leads the Help Desk team, manages large accounts, and secretly dreams of becoming a rapper with the stage name of "Lil AJ".

Nick Mishler

Director of IT & Facilities Management

He keeps our servers, networks, and buildings running smoothly. In his spare time you can find him competing in garden tractor pulls (he is a champion); or scaling something of great height.

Our Founder

Ken Pflederer


CSE Software™ was founded in 1990 by Ken Pflederer. He quickly moved from a single employee conducting computer training, to adding employees, software development and many other services over the years. Ken’s philosophy on business led to the company’s growth and success since then. Ken retired in January 2020. The vision and values he laid out—and his passion for keeping CSE a company that cares for its employees and clients—continues on in the passion of his leaders and teams.
