About Trellis-Strategy

Trellis-Strategy supports strategic planning, project management, and operational foundations with a focus on the water-energy-food nexus.

We strengthen organizations by building and maintaining foundations that support sustainable growth. We formalize Standard Operating Procedures, clarify team roles and organizational structures, develop administrative calendars, and support hiring and onboarding processes, ensuring that back-end systems are organized, efficient, and aligned with your mission.

Building on that foundation, Trellis-Strategy develops strategic plans that enhance organizational effectiveness and drive meaningful impact. We create actionable business development and marketing strategies rooted in each organization’s goals, design processes that help teams navigate change and complexity, and foster community engagement to support long-term success.

With deep expertise in the water–energy nexus and a focus on social equity, we help organizations launch new initiatives, facilitate programs, and manage projects. We enjoy bringing your vision to life and maximizing its impact through educational campaigns, community engagement workshops, or stakeholder sessions.

With over a decade of experience working across the water-energy-food nexus, Trellis-Strategy brings practical, results-driven planning, facilitation, and organizational tools to every engagement.

Inspired by the way a trellis supports and guides a plants' healthy growth, our firm helps organizations lift ideas off the ground and build lasting momentum.
