Lead with clarity.
Live with purpose.
Executive leaders and teams must combine skill, insight, and strategy. The best ones don’t do it alone.
I work alongside senior and executive leaders who are navigating complexity and feeling the weight of their responsibilities. Drawing on deep experience in organizational leadership and the Birkman Method — one of the most sophisticated behavioral tools available — I help leaders understand themselves more clearly, make better decisions, and build teams that work well together.
This is not generic coaching. It is rigorous, personal, and built for leaders who desire sustainable transformation and impact.

How I work:
I offer three distinct pathways, each designed for experienced leaders who want more than surface-level insight.
Leadership Clarity Intensive
A six-month, high-touch executive coaching experience for leaders who want deep insight into how they lead, decide, and relate.
This pathway integrates the Birkman Method with your actual leadership environment to build a precise understanding of your patterns, strengths, stress responses, and impact on others. The focus is clarity that translates into wiser decisions, stronger communication, and sustainable leadership rhythms.
Suited for leaders ready to invest in meaningful, measurable growth that endures beyond the program.
Executive Leadership Retainer
An ongoing, high-trust coaching partnership for senior leaders who need a thinking partner in real time.
This work is designed for leaders facing high-stakes decisions, complex relationships, and sustained pressure. Rather than a fixed curriculum, it evolves alongside your leadership context — offering perspective, steadiness, and strategic support as situations arise.
Ideal when leadership demands are continuous and the cost of isolation is high.
Team Development Intensive
A Birkman-based leadership experience for executive and senior leadership teams.
This pathway strengthens trust, communication, and alignment by addressing real team dynamics beneath the surface. Every participant completes a Birkman assessment and receives an individual debrief before a custom-built team session. The result is clearer expectations, reduced friction, healthier decision-making, and stronger collaboration.
Practical, data-informed, and designed to improve how leadership teams function under pressure.
Who I work with:
My coaching is designed for leaders and teams who:
- Carry significant responsibility and influence
- Are navigating complexity, not certainty
- Want clarity and steadiness, not quick fixes
- Are willing to reflect, adapt, and grow
If you are looking for generic leadership advice or surface-level motivation, I am not a good fit.
If you are looking for a trusted thinking partner to help you lead with wisdom, alignment, and long-term perspective, let’s talk.
Who am I?
My coaching draws on decades of senior leadership experience, including my current role as President of MB Seminary and my work as a Birkman Certified Professional.
I understand what it means to lead within complexity — to work with boards and executive teams, to guide change, and to make decisions that affect people and institutions over time. Leaders trust me because I have carried the pressures they face and can help them navigate those pressures with clarity and purpose.
Outside the boardroom, I train as a trail runner and hybrid athlete. That discipline reinforces something true about leadership: clarity, resilience, and endurance are built through intentional rhythms, not intensity alone.
Testimonials
What They Say
Mark's coaching helped me understand myself and others in new ways. I’ve noticed real growth in how I communicate and collaborate with my colleagues, making leadership feel more natural and connected.
I highly recommend Mark’s leadership training program for business leaders to better understand your personal leadership style and the leadership style of your team members. It is full of informative content that can be immediately utilized in the work place to improve your team dynamics and communications.
Birkman coaching opened my eyes at how I am portrayed by others in the work field and what kind of leader I strive to be. It also narrowed areas that were my strengths and gave me the motivation to invest in myself in order to advance my career.
Mark's unique combined professional and personal experiences, along with his ability to coach and communicate, have been invaluable to me as a learning leader in my life and professional position. I would highly recommend his coaching to any individual who is aspiring to become or grow as a leader, regardless of vocational field.
I loved the simple, yet meaningful 6×6 Leadership lessons. I can easily take these lessons and apply them and share them with my team. I also appreciated the group dynamic. The lesson on leadership voice helped me to understand why I lead and speak the way that I do, and gave me the freedom to lean into that voice (instead of feeling guilty about it) while developing others.
I really appreciated seeing how some of what I normally do in my work is actually different from my interests. In addition, it was eye-opening to see how different I respond under stress. The most valuable part of the Birkman assessment and follow-up meeting was seeing how what I need from others differs from how I typically operate.
