About MDG

Boutique capability. Strategic depth. Embedded where the work happens.

Sustainability and people strategy are no longer separate conversations. The organizations leading in construction and development today are the ones that have connected their people strategy, their culture, and their environmental performance into a single operating approach. That is exactly where MDG works.

A team working together in a contemporary office

We are a boutique sustainability and people strategy consulting firm with a team of experienced professionals across green building, workforce planning, organizational development, and sustainability education. We place the right people directly into your team, in the right role, for exactly as long as the work requires. When the project is complete, we step back. No ongoing contract, no ambiguity about scope or cost.

Our clients are small to mid-sized for-profit organizations in construction, development, engineering, and architecture, moving fast, running lean, and needing expertise they don't carry in-house. They want direct conversations, practical outcomes, and a firm that respects their time and budget.

Three disciplines, held together rather than kept apart: the people, the leadership, and the sustainability strategy that connects them.

Who we work with

Depth in both disciplines, at the pace of a growing business.

The intersection of sustainability and people strategy requires a partner with depth in both, and the agility to work at the pace of a growing business.

Organizations ready to move forward.

We work with organizations at every stage, from those still shaping their direction to those ready to turn established goals into action. Whether you're strengthening your workforce, developing leaders, building sustainability capability, pursuing certification or connecting these areas together, we'll meet you where you are.

Ariva Resorts, a master-planned estate community

MDG helped us see wellness at the scale of an entire community, not just a single building. That connection between human health and design is exactly what we set out to build.

Trish brings over 25 years of experience at the intersection of sustainability and people strategy, spanning green building certification, organizational development, workforce planning and sustainability education. It's a rare combination in the consulting sector, and one that's directly relevant to the organizations MDG serves.

This foundation shapes how MDG approaches every engagement: evidence-based, practically delivered, and connected to real organizational outcomes. She's known for direct advice, fast execution, and an honest read on what's achievable. Clients get a clear picture of what's possible, what it will take, and what it will cost, before any work begins.

Design isn't just in our name at MDG; it's how we work. We don't just plan for sustainability and people strategy separately and hope they align. We design them together, from the start, so a plan doesn't just sit on paper; it becomes an organization that's actually more resilient.
