About Us

The Strategic Design Group (SDG) is a nationally recognized consulting firm specializing in executive coaching, leadership development, strategy alignment, and organizational transformation. Headquartered in Illinois, we proudly partner with public sector agencies and human services organizations to strengthen leadership capacity and deliver measurable, sustainable results.

Founded in 2019, SDG is led by Diane Grigsby Jackson, a seasoned leadership strategist with nearly 30 years of experience, including over 19 years dedicated to leadership consulting in human services, education, and nonprofit systems. Her deep expertise and systems-level insight guide our work with mission-driven organizations nationwide.

At SDG, we believe that lasting change begins with connected leadership—leaders who are self-aware, relationally agile, and aligned with organizational purpose. To cultivate this, we integrate the DISC Behavioral Assessment as a foundational tool for improving communication, navigating change, and building cohesive, high-performing teams.

We don’t just deliver training—we coach and develop leaders who turn strategy into action, inspire their teams, and drive real-world impact.


Whether you’re launching a new leadership initiative or building on existing capacity, we can create customized leadership solutions that are modular, scalable, and tailored to your specific needs.
