About Us
OneThree12 is led by a founding team of committed, seasoned coaches and professionals. Our team has decades of shared coaching, executive leadership, service and discipleship experience.
OneThree12 is inspired by the coaching journeys of the founding team. After decades of watching the impact that intentional coaching had on the lives of men and women in business, ministry and at home — the founding team came together with a vision for an affordable, multiplicative coaching experience.
As the stories of impact increase, people want to become coaches and bring others along. This cycle of sharpening, growth and replication is what Jesus envisioned in Matthew 28 and is fundamental to what we do.
