Mark Brewer retires from DLA Energy after 37-year career

After 37 years with the federal government, Mark Brewer has retired as chief of the Joint Integration Management Division at Defense Logistics Agency Energy, capping a career that tracked decades of change in the Defense Department’s bulk fuel enterprise.

Brewer began at DLA Energy as a college sophomore in the Cooperative Education Program, working as a student trainee in contracting. He supported contract specialists with solicitations, bid evaluations and contract awards, and handled small emergency purchases. Early exposure to operations came through the agency’s Multifunctional Program, where he cross-trained in roles such as inventory management—experience that, he said, sharpened his understanding of the bulk petroleum supply chain. A guiding perspective took hold after he heard Army Brig. Gen. James Bickford state, “In war, nothing happens until something moves, and all things move with petroleum.”

When Brewer entered government service, the supply chain was managed largely by hard-wired telephones and hard-copy documents prepared by clerks. Over the years he held a range of positions, including contracting specialist, ordering officer, transportation specialist, commodity business specialist, inventory management specialist, energy initiatives program manager, strategic energy analyst and supervisor.

Colleagues said Brewer’s technical fluency and personal steadiness made him an anchor within the organization. “From the moment I began working with Mark, it was immediately clear that he was the heart of the organization,” Walt Allen, chief of the Joint Integration Management Division, said. “My first impression was that he was the center of all activity; if Mark didn’t know someone, they most certainly knew of him.”

Others highlighted his meticulous approach. “We balanced each other out perfectly,” said strategic energy analyst Jim Eberhardt, who worked with Brewer on Joint Fuel Bladder Specifications. “Mark was the meticulous, ‘in the weeds’ professional who cared enough to ensure every detail was right… Mark leveraged his extensive background in contracting and bulk fuels to expertly navigate and overcome obstacles that would have otherwise brought the project to a standstill.”

Colleagues also pointed to Brewer’s impact across the wider joint petroleum enterprise. “When I think of Mark’s professional expertise, the first thing that comes to mind is his deep understanding of roles and responsibilities across the joint petroleum enterprise,” said program manager Sam Cooks. “As secretary of the Component Steering Group, he was on the front line of driving enhancements across the joint fuel supply chain.”

Brewer said a career highlight was a six-month assignment as an ordering officer for the Defense Fuel Office Balkans in Croatia under DLA Energy Europe & Africa. Serving as the central point of contact for fuel orders and deliveries across Croatia, Bosnia and neighboring countries, he supported NATO member nations.

He cited particular pride in supporting the Bulk Petroleum Executive Agent mission, which sought to centralize and standardize the bulk petroleum supply chain. That mission formally ended with the fiscal 2022 National Defense Authorization Act, but his colleagues said the mindset endured. “When the fiscal year 2022 National Defense Authorization Act officially concluded the Executive Agent mission, Mark’s dedication to its principles didn’t waver,” said Kent Comstock, a logistics systems analyst. “His role with the Component Steering Group was formally scrubbed, but Mark kept his ‘EA goggles’ on, continuing to apply a critical, forward-thinking approach every day. I think the whole team is still bought in to one degree or another, and Mark has something to do with that.”

Allen described Brewer’s leadership as calm and quietly influential. “Working alongside Mark on a daily basis provided a constant feeling of security and calm. Knowing he had your back, no matter the circumstance, was incredibly reassuring,” Allen said. “His leadership style was a masterful blend of quiet influence and steadfast support.” Comstock said Brewer’s habit of listening to others and weighing their views before deciding helped build trust across the team.

Asked what advice he would offer to new DLA Energy logisticians, Brewer emphasized the fundamentals—show up on time, take responsibility for mistakes, and learn from those with more experience. “Public service is simply one of the highest callings an individual can have,” Brewer said. “Service to others is both civic and biblical and should be pursued by all on a daily basis.”
