Brett Antczak, MHA, Former Hospital CEO | Author | Certified Midlife Mastery & Leadership Coach with the Age of Advantage and Proud Dad

Brett Antczak does not just teach leadership and midlife transition; he has personally architected it under the highest stakes. As a former Hospital CEO with a master’s in healthcare administration, Brett has spent the last three decades at the center of systemic complexity, human crisis, and fiscal responsibility within rural hospitals and regional health systems. Today, he is the voice of the Age of Advantage, a specialized leadership and midlife reinvention system for high-performing adults who are ready to move from.

Brett’s authority is built on a diverse and rigorous teaching & speaking pedigree. Throughout his career as a healthcare leader, he has commanded the stage in front of audiences of thousands as well as being a guest lecturer in university, community college, and high school classrooms. This breadth of experience—combined with years of intensive one-on-one mentoring—allows him to translate high-level executive discipline into universal truths that resonate with anyone seeking to lead a life by design.

Brett’s deep understanding of midlife reinvention is forged from personal experience. Over the last decade, he has successfully navigated a series of profound trials, including a 120-pound weight loss journey, loss of both his parents, a cancer diagnosis, divorce, and significant career pivots. These opportunities have helped him to liquidate his own outdated identities and rebuild his life from the ground up. He speaks not as a theorist, but as a man who has been tested in the fires of real-world adversity and emerged with a clearer, more powerful vision.

At the core of Brett’s work is this methodology, supported by the world-class Dream Builder and Life Mastery series. By auditing the 4 Domains of Life; Health & Well-Being, Love & Relationships, Vocation, and Time & Money Freedom. Brett helps capable adults stop treating midlife as a crisis or discomfort and start treating it like a design problem that can be restructured and rebuilt.

In his book, ARCHITECTING THE SOVEREIGN LEADER: Engineering for a Life by Design – Liquidating Burnout | Reclaiming Strategic Command, Brett provides a blunt, seasoned disagreement with the cultural narrative of midlife crisis and decline. He asserts that midlife is a leader’s ultimate competitive asset—the first season where experience, pattern recognition, and emotional regulation finally align to create a “Sage” level of influence.
Based in Washington State, Brett works with high-authority leaders and people in midlife globally, ensuring their second half of life isn’t just a continuation of the first, but a masterpiece of intentionality and legacy.
