Supply Chain, Logistics & Operations Consulting Built for Real-World Execution
Experience Over Theory. Facts Over Narratives. Outcomes Over Everything
A Supply Chain Consultancy — Built Differently
Focused on the Facts
Dayton Management Group (DMG) is built around a different idea: experienced operators should solve operational problems. We bring proven industry professionals together around each client’s specific challenge—not a traditional consulting staffing model.
DMG is obsessed with your customers and the outcome. We challenge assumptions, cut through industry narratives, and let the facts lead. Every engagement starts with the realities of the operation, the economics behind the decisions, and a relentless focus on what creates measurable value.
Only facts. Better decisions. Stronger execution. Measurable outcomes.
Our deep professional network and flexible structure allow us to rapidly assemble the right expertise for each engagement, scaling our capabilities around the specific needs of the client rather than forcing the client into a predetermined consulting model.
Operating Experience. Measurable Impact
Decades of Execution Across Complex Supply Chain and Operations
DMG was built on more than 30 years of hands-on operating leadership across supply chain, fulfillment, distribution, transportation, technology, and organizational performance.

Experience Matters When the Cost of Getting it Wrong is High
DMG brings that operating experience to every engagement—helping leadership identify where performance is being lost, challenge assumptions, make better investment decisions, and convert operational improvements into measurable business results.
Our Founder
Facts, Execution, and Lasting Results
Jon Siffing is the Founder of Dayton Management Group (DMG) and an operations executive with more than 30 years of hands-on leadership experience across supply chain, fulfillment, distribution, inventory, transportation, and complex operating environments. His career includes senior leadership roles with Gap, Sephora, Sally Beauty/CosmoProf, and Ralphs Grocery, where he led large-scale fulfillment, distribution, transportation, network, and business transformation initiatives.
Jon has built his career around improving complex and underperforming operations. He brings clarity, discipline, and accountability to organizations facing rising costs, service challenges, capacity constraints, and execution gaps. Across his executive and consulting career, he has led initiatives responsible for more than $500 million in identified and realized cost savings.
Jon founded DMG after seeing a growing disconnect between investment and results. Technology, automation, and operating complexity were increasing, but too many organizations were spending more without seeing the expected improvement in cost, productivity, service, or return on investment. He believed there was a better approach: establish the facts, understand the problem before prescribing the solution, and put experienced operators behind the work.
His leadership philosophy starts with understanding what is actually happening inside the business—not what reports, assumptions, or established narratives suggest is happening. From there, the focus is on identifying the issues that matter most, setting clear priorities, establishing accountability, and aligning leadership and frontline teams around execution. The objective is to stabilize performance, remove unnecessary cost and complexity, and build improvements the organization can sustain.
At DMG, Jon brings together experienced operators and industry professionals to help leadership teams solve complex supply chain and operational problems, improve service, control costs, strengthen execution, and make better investment decisions. The focus is straightforward: turn facts into better decisions, better decisions into action, and action into measurable business performance.
Only Facts. Better Execution. Smarter Investment. Stronger Performance. That’s the DMG difference.
Why Organizations Bring In DMG
When Operational Problems Become Business Problems.
Organizations typically bring in Dayton Management Group when rising costs, declining productivity, capacity constraints,
service failures, technology decisions, or execution gaps begin affecting margin, growth, customers, and business performance.
DMG brings experienced operators into complex supply chain, operations, fulfillment, transportation, technology, and organizational challenges to establish the facts, identify where performance is being lost, and determine what needs to change.
The common thread is simple: something is costing money, creating risk, limiting growth, or affecting customers. DMG helps leadership cut through the noise, quantify the opportunity, make better decisions, and turn those decisions into measurable results.
