Who This Is For

For Leaders Committed to Becoming More.

The Leadership Mastermind is designed for CEOs, founders, executives, and emerging leaders who believe there is another level of leadership, and life, they are capable of reaching. Whether you're scaling an organization, developing future leaders, navigating transition, or simply refusing to settle for your current potential, this retreat is for those who are committed to continuous growth and leading with greater intention.

"I've built something successful, but I feel stuck."

"I've always felt there has to be more in me."

"I feel like my business needs stronger leadership than I am capable of."

"I'm leading everyone else but neglecting myself."

"It's all on me. It's exhausting."

"I work hard and I'm successful — but I don't feel fulfilled."

Why This Exists

Most leaders aren't stuck for lack of effort.

This retreat exists because the next steps in your journey require the next level of personal growth. Success got you here. A different version of leadership, and a different version of you, will get you there.

"You create a beast, and then work tirelessly to feed it, rather than letting the beast feed you."

Most leaders work so hard, and do so much, that they lose sight of what it was ever about. This is a retreat for the leader who is ready to stop feeding the beast.

We work in this order — always

ME

Leadership of myself. Without change here, nothing else shifts or transforms.

US

Leadership of my team and my family — the people closest to the life I'm building.

IT

Leadership in business. The outcome, not the starting point.

The Experience · Our Why = Inspiring Insight

Three days. One arc: Awaken, Equip, Empower.

Any change starts with awareness. With insight from head and heart, we equip you with the building blocks to better. And no change is successful without commitment — so we empower you to act, no matter what.

DAYI Awaken — The Foundation of Exceptional Leadership

See yourself clearly

Great leadership begins with self-awareness. Before you can effectively lead others, you must first understand yourself.

You'll explore the beliefs, values, and thought patterns that shape your leadership and your life. Through thought-provoking discussions and personal reflection, you'll gain greater clarity about your purpose, core values, insecurities, and the mental models that influence your decisions. You'll discover the difference between intellect and intuition, learn why we experience life through our thinking, and explore how our feelings serve as a powerful dashboard for personal growth.

We'll also examine what authentic leadership truly means, the role vulnerability plays in leading well, and where you stand on the journey from positional authority to relational authority to transformational leadership.

DAYII Equip — The Architecture of Intentional Leadership

Learn to play with what you find

Exceptional leadership isn't accidental — it's built on timeless principles, practical frameworks, and intentional action.

You'll explore the essential building blocks that distinguish great leaders from great managers and learn how to lead with greater clarity, purpose, and influence. Together, we'll examine how to align your Why, What, and How, adapt your leadership through situational leadership, and understand why the first responsibility of every leader is to ensure there is leadership throughout the organization.

You'll also identify the people who should make up your personal "Olympic Coaching Team," evaluate where your attention is most needed, and explore what it means to master leading leaders.

DAYIII Empower — Turning Insight into Lasting Change

Leave with a plan that holds

Awareness creates clarity. The right building blocks create confidence. Commitment is what creates transformation.

On the final day, you'll develop a practical plan to turn what you've learned into meaningful action. Rather than leaving inspired but uncertain where to begin, you'll identify the one change that will create the greatest positive impact and build the habits and accountability needed to sustain it.

Together, we'll explore what a commitment to peace of mind looks like in your life today, apply principles to create lasting change with simple and practical actions. You'll also establish accountability through action plans and peer partnerships to ensure your momentum continues long after the retreat ends.

You'll leave with more than inspiration — a clear roadmap, meaningful accountability, and a commitment to becoming the leader, partner, and person you aspire to be.

What You'll Leave With

Clarity is the catalyst of change.

This isn't about doing more. It's about being more — and finally discovering who you actually are, underneath who you've always thought you had to be.

Awaken

Greater self-insight

Identify your leadership blind spots and gain more clarity about yourself than you've had in years — awakening awareness of how your life can actually be.

Equip

Tools you can use Monday

Strengthen your decision-making, clarify your strategic priorities, and gain the confidence and language to share these concepts with clarity and impact.

Empower

A plan, and a peer group to keep it honest

Leave with a commitment and a plan to deliver future success — and a trusted network of fellow leaders to keep you on track for months after.

The Mastermind

A small circle. Chosen, not open.

This is invitation-only, capped intentionally small, so the trust in the room can go deep enough to matter. The experience starts with the retreat and continues for six months after.

Your Facilitators

Guided by leaders who've done the inner work themselves.

Brian Brault

Founder, Legacy of Significance

An entrepreneur who built three companies, including a Property Maintenance firm that grew to 300 people and $12 million in revenue without a formal sales team, on reputation and human-centered leadership alone.

Over 23 years with the Entrepreneurs' Organization, Brian rose from local chapter leader to Global Board Chairman, helping design the Leadership Academy and executive education programs that have since developed thousands of leaders across 60+ countries.

Antony Tinker

Facilitator

A lifelong learner who has always naturally stepped into the role of leader, first because no one else would, later because he had something to give, and something to learn.

Antony spent two decades in global pharmaceuticals, earning a reputation as "the turn-around guy" taking products, brands, teams, and entire geographic regions from decline to rapid, sustained growth.
