About Us

Principle Source provides Coaching and Consulting services to leaders of small and medium size businesses, government, and non-profit organizations and to individuals seeking to improve their personal effectiveness. 

We partner with our clients to create sustainable growth by focusing on building awareness, clarity of purpose, and capacity rather than dependency.  Our approach is to cultivate and plant the seed and then empower you to own your personal and organizational development to achieve desired business results.
