Transforming lives and cultures through servant leadership

Contrary to what you may believe, institutionalizing a culture of servant leadership is not a “soft” approach to management. It takes dedication and a life-long commitment to serving others, measuring results, and equipping yourself and everyone on your team to live with purpose. Triune Leadership Services can help you discover the power of servant leadership! The only question is, when are you ready to begin?

Meet David Schmidgall

Partner, Triune Leadership Services

David’s career spans 25 years, with a majority of that time spent in an executive role in a multi-generational family-owned business with six locations across four states. Culture at the century-old business had become stuck and stagnant and was often hard on people, tolerant of bad behaviors and encouraged silos and politics. Servant leadership was the foundation that transformed the organization, and it was made possible because of an incredible team committed to serving others even when it came with a personal cost. Ultimately this led to significant financial results, higher retention rates, more consistent values to behaviors and life-long friendships.

David also led through significant periods of change management including a cash crisis in 2007-2009 and two acquisitions, the first being private in 2011 and the second public in 2021.

Our Philosophy

True, lasting transformation is not possible without Jesus


We believe at work, as in life, we cannot maximize our potential as servant leaders, without recognizing the saving grace of Jesus and ourselves being transformed because of our relationship with him. The outward transformation in how we lead, and our behavior, is driven by this inward transformation.

You don’t have to have direct reports to be a leader


While many organizations focus on training and growing their current leaders, we believe that servant leadership training is valuable for all team members, from executives, to emerging leaders, to employees. Empowering all team members to practice the servant leadership framework creates a cultural alignment within the organization and positively impacts performance and employee relationships, as well as elevates team members’ leadership skills, allowing them to be better leaders not just at work, but at home and in the community

Anyone can learn to apply the servant leadership approach


Whether you are an intern, a new leader or an executive with years of experience under your belt, you can learn to apply the servant leadership philosophy. Likewise, whether you grew up in church or you are new to the teachings of Jesus, you can learn from his leadership model and use servant leadership skills in your everyday life.

Theory not supported by actionable tools doesn’t create a true transformation


At Triune Leadership Services, we value application. Simply learning a concept doesn’t often make a lasting difference in leaders’ lives. We are passionate about helping you operationalize each concept that we teach through practice, role-play, and a number of other proven tools that allow you and your team to become confident practitioners of servant leadership.
