Some people see problems.
ISG looks for the system underneath them.

Tanya Johnson is the founder and CEO of Impact Strategy Group. For more than two decades, she has worked inside organizations that were doing everything right, caring deeply, working tirelessly, and still not producing the impact they were capable of. That pattern is what Impact Strategy Group was founded to address.

Where it started

Same children. Different systems.

Tanya was bused into a magnet school while her neighbors attended dramatically different local schools. Same children. Different systems. Different outcomes. That experience raised a question: what does it take to build conditions where anyone can thrive, not just a fortunate few? It has shaped every chapter of her career since.

Proof of concept

Rebuild the foundation first.

Tanya started her career as a teacher in Compton, then taught fifth-grade math in Newark, New Jersey, where her students arrived with significant foundational gaps. She rebuilt the foundation first, before moving to grade-level content.

The pattern, repeated at scale.

That result wasn't a one-time win. As a staff developer in Washington Heights, she installed the same structures across an entire mathematics department, grades five through twelve — and scores rose 20% under her leadership. She took that same discipline to Brooklyn as Director of Mathematics across a network of schools, proving the model held at network scale, not just within a single building. She went on to co-facilitate a citywide instructional initiative alongside a nationally recognized architect of curriculum design theory, work that drew as much on her academic training in adult learning theory as on what she'd already proven in classrooms and school systems. As Vice President of Program Design and Staff Development for a nonprofit with a $16M annual operating budget, she built and led an entire department translating research into practical tools for educators and leaders. It was her first experience designing organizational infrastructure, not just instructional strategy.

That same pattern, talented people, important missions, underbuilt conditions, was showing up everywhere she looked, across every sector. She didn't have a name for it yet. Just a habit of noticing when people agreed on the words but not the meaning. She started calling the misalignment Shades of Blue, everyone certain they meant the same thing, each one picturing something different. Naming it was the beginning of Shared Seeing. It's what led her to found Impact Strategy Group, and it's still how the work gets done.

Long before ISG had a name for the discipline, the pattern was the same. She wasn't just solving the problem in front of her. She was rebuilding whatever kept producing it.
