John Barker

Principal | Director of Finance

“My favorite quote is from author and educator Peter Drucker: ‘What gets measured gets managed.’ Personally, I really enjoy helping non-finance staff understand the financial end of things.”

John Barker directs the financial operations at Acentech, responsible for revenue forecasting, budgeting, accounting functions, and overall performance assessment and risk management. He has over a decade of financial leadership experience with two business units of a global environmental engineering firm and as an auditor. He brings a hyper-focused approach in leveraging technology to improve processes for identifying risk and facilitating financial understanding and concepts that drive critical decision-making and its impact on business excellence.


When not crunching numbers at Acentech, John enjoys being a dad: coaching little league and flag football, hiking with the dogs, fixing up the house, and supporting his favorite sports teams.
