About Us

Combining strong leadership development with effective strategy implementation. 

Our Why

Raising the Leadership Bar

Leadership defines the workplace. Inspired leaders have the ability to help their teams see into the future, and believe in their abilities to create that future. This is how organizations move forward.

Each organization sets its own expectations for leadership competencies. Among these often are integrity, respect, promoting innovation, achieving results, and holding strong accountability for staff at all levels.

How does your leadership line up?

At Sage & Summit our purpose is to raise the leadership bar anywhere and everywhere. Through our executive coaching and leadership development strategies we help individuals and organizations to combine strong leadership with effective implementation strategies to effect change, improve sales, and generate results.

Sage & Summit is here to walk with you through periods of change and adjustment. We help you tackle and remain ahead of turbulence and change. Our facilitation team has more than 50 years combined experience in shaping organizations, planning for growth, transformation, and rapid change.
