CTI Impact

To date, more than 52,000 coaches, consultants, managers, and new career explorers have been trained through CTI. CTI-trained coaches come from varied backgrounds such as entrepreneurs, CEOs, scientists, medical and technical specialists, parents, educators, therapists, and community leaders. Many will go on to focus in a specialty segment such as relationships, executives, career, transitions, teenagers and more.

In addition, major organizations, such as British Gas, Capgemini, Cargill and RBC Financial have offered Co-Active Coach® training within their organizations to increase management and employee effectiveness.


The Coaches Training Institute (CTI) was founded in 1992 by three of the earliest recognized luminaries in coaching – Laura Whitworth, and Karen and Henry Kimsey-House – whose earlier collaboration with Thomas Leonard gave rise to coaching as an industry.

Headquartered in the San Francisco Bay Area, CTI is the largest and oldest in-person coach training school in the world and the only program to teach CTI's ground-breaking Co-Active® Model of coaching. CTI is also the very first organization accredited by the International Coach Federation (ICF).

CTI's founders, along with Phil Sandahl, are co-authors of the industry bestseller, Co-Active Coaching, now in its third edition with 100,000 copies sold.
