Team

The Gemba Academy team operates out of offices in California and Texas. We work hard to practice what we preach, especially with regards to the "respect for people" principle of lean, and have developed an innovative Culture Code.

Founding Partners

The founding partners of Gemba Academy come with lean consulting, lean and six sigma training, and executive-level lean transformation experience. This is the Gemba Academy difference: we're lean and six sigma experts first, who then learned how to create great training videos.
