PLEXSYS Introduces New Chief Financial Officer

Jul 27, 2021 | By: Tara Marta

CAMAS, WA (July 27, 2021) – PLEXSYS Interface Products, Inc. (PLEXSYS) Board of Directors appointed Doug Childress as Chief Financial Officer (CFO), effective November 16, 2020. Childress jumped in with both feet and immediately started contributing to the PLEXSYS success story. Based on this momentum, the November announcement was overshadowed by a flood of new tasks and the feeling Doug had been a part of the team for a long time.

“With the retirement of Joe Doubrava, our long-time CFO, we searched nationwide… there was, and is, no better person to take on the PLEXSYS CFO role. We continue to wish Joe all the best in his retirement,” stated Ron “Opie” Wiegand, PLEXSYS President & CEO. “Doug is a proven leader with extensive experience in the defense industry. His experience in Defense Contracting with technology companies aligns with our vision and strategic objectives. His positive attitude and work ethic are contagious, and he exudes our core values—integrity, excellence, teamwork, and agility. He is a great match for PLEXSYS. Our global team and our customers are benefitting every day from Doug’s engaged leadership.”

Childress was previously the CFO at NetCentrics, an IT and Cybersecurity defense contractor in Herndon, VA. As a CPA and graduate of Southern Methodist University, Childress has a long history of growing defense contractors, mergers and acquisitions, and system upgrades. In addition to NetCentrics, Childress brings strategic and tactical leadership experience from Private Equity backed firms Tristar Aerospace, Westar Aerospace, Defense Group, and HDT Global. Doug and his family relocated to the PLEXSYS corporate headquarters in Camas, Washington, from Missouri.

“I am both humbled and excited for the opportunity to work with such a talented team of individuals,” Childress stated. “PLEXSYS products provide leading-edge tools that enable readiness training across C2, shooter, and intelligence communities. I am pleased to help lead the company’s profitable growth.”
