MONDAY MATTERS – Mission-Driven Leadership with Trevor Timmerberg

This week on Monday Matters, we are taking time to learn from Dr. Trevor Timmerberg, who serves as the Assistant Superintendent of Catholic Schools for the Archdiocese of Louisville, where he supports principals and school leaders in advancing Catholic identity, academic excellence, and mission-driven leadership across the district. 

A former principal of Saint Mary Academy, Dr. Timmerberg helped lead the school to become a nationally recognized Model PLC at Work campus and is regarded for his commitment to forming disciples through collaborative, faith-centered school cultures. 

His background spans educational leadership, teacher formation, strategic planning, and governance, and he is passionate about helping Catholic educators integrate the Gospel mandate with the best of professional practice. Dr. Timmerberg was also an Army officer and is a practicing Catholic whose work is rooted in service, stewardship, and developing leaders who inspire others to holiness and excellence.

In this episode of Monday Matters, Will Parker sits down with Dr. Trevor Timmerberg, Assistant Superintendent of Catholic Schools for the Archdiocese of Louisville, for a rich conversation about leadership, service, and growth. At the heart of the conversation is the idea that leadership is not about doing the work alone, but about building the capacity of others so the mission can thrive.

Trevor reflects on his years as principal of St. Mary Academy, where he helped lead the school to recognition as a Model PLC at Work campus. One of his biggest lessons from that experience is that a leader is only as strong as the team around them. Rather than centering leadership on one person, he emphasizes shared ownership, distributed responsibility, and the importance of developing teacher leaders, assistant principals, and other members of the school community. For Trevor, the role of the leader is not simply to solve problems personally, but to create the conditions for others to lead well.

A major theme throughout the episode is servant leadership. Trevor explains that although education, military service, and faith may seem like very different spheres, they all point him back to the same foundational principle: leaders exist to serve. He talks about stewardship, modeling expectations, and helping others see both the purpose of their work and their place in it. Drawing from military leadership, he describes how strong leaders provide the what and the why, while empowering others closest to the work to determine the how. That kind of trust, he explains, creates both ownership and momentum.

Will and Trevor also discuss what it means to support a system of schools rather than a traditional school system. Trevor explains that the Archdiocese of Louisville operates with both shared mission and some local autonomy, which makes influence, collaboration, and credibility especially important. He describes the intentional ways their system supports leaders through regular meetings with principals, assistant principals, counselors, and learning coordinators, along with professional development for teacher leaders and staff. What stands out is that these meetings are not simply held for the sake of meeting. They are designed to advance the mission of the schools and help leaders meet the needs of students.

Another highlight of the episode is the conversation around the Grow Leadership Academies and Mastermind groups that Trevor and Will help facilitate together. Trevor shares what it was like first to participate in one of these academies as a principal and now to co-facilitate leadership development for others. One of the key phrases that has stayed with him is, “The smartest person in the room is the room.” That belief reflects the deep value of collaboration and reinforces the idea that continuous improvement is strongest when leaders learn alongside one another. In these spaces, leaders are not isolated. They are challenged, encouraged, and sharpened by peers who understand the realities of the work.

When describing the difference between the Grow Academy and the Mastermind experience, Trevor notes that the mastermind format especially highlights the value of reflective questioning. Instead of rushing in with answers, leaders are invited to process real challenges with the support of thoughtful peers. He points out that some of the best leadership growth happens not when someone gives advice, but when the right questions help a leader discover the next best step on their own. That reflective practice, grounded in trust and confidentiality, helps leaders become more thoughtful, self-aware, and effective in the face of difficult decisions.

For leaders who may not have access to a strong support system, Trevor offers encouragement to keep growing anyway. He talks about the abundance of resources available through books, podcasts, courses, and professional networks, and he encourages leaders not to limit themselves only to education content. Sometimes, he says, the most valuable leadership insights come from outside the field, whether from business, ministry, the military, or even fiction. Curiosity matters. So does finding someone else to learn with, whether formally or informally, because growth is almost always stronger in community than in isolation.

The episode closes with a strong word of encouragement for school leaders. Trevor reminds listeners that leadership can be expressed from any role and that those serving in schools are doing deeply important work. He especially affirms principals and assistant principals, acknowledging how demanding their work can be while encouraging them to keep the main thing the main thing. Students matter, and so does the leadership required to support them well. Will closes the episode by reminding listeners that their mission matters and that continued investment in their own growth is what makes it possible to fulfill that mission with greater impact.
