Who We Are
When it comes to cultivating human potential, it’s important to work with people you can trust.

Mangum Partners LLC is a true partnership: you and us. Change doesn’t happen in a vacuum. It takes hard work, a positive attitude, desire and, most important of all, a trusted coach.

Credentialed by the leading training and change-makers in the coaching and leadership development fields, we use a unique down-to-earth coaching approach that combines deep listening with incisive inquiry to help clients tease out, for themselves, the best path forward. Then, together, we write the blueprint and build the new way of being that brings out the best in people. Because, to us, it’s all about you–your gifts, your strengths–and helping you create a positive plan of action to leverage them.
