Matthew Rehrig on Type 1 Diabetes, Gym Ownership & Fatherhood | Hidden Foundations Ep. 19

with

In this episode of Hidden Foundations, Kendall is joined by Matthew Rehrig, a gym owner, father, and Type 1 diabetic, to unpack the pressure behind building a business while managing a relentless health condition. Matt shares how 2015 changed everything: a new baby, a new house, a young marriage, a risky gym investment, and the stress that surrounded his early years as an entrepreneur. Six months after opening the gym, he was diagnosed with Type 1 diabetes, forcing him to manage blood sugar, insulin, workouts, family life, and business ownership every day. Kendall and Matt also explore door-to-door sales, fitness coaching, confidence, keeping promises to yourself, raising three sons, his complicated relationship with his father, and how early family patterns shape the way we lead, parent, and survive pressure.

Ari Simmons on Becoming a World Champion and Chasing the Olympics

with Ari Simmons

In this episode of Hidden Foundations, Kendall is joined by Ari Simmons, a world champion epee fencer, coach, and Olympic hopeful, to explore what elite sports really build inside a person. Ari shares how he went from being kicked out of fencing class for goofing off to becoming first in the U.S. and winning a world championship in the 17-and-under category.
The conversation moves through obsession, discipline, ego, youth sports pressure, parental support, Notre Dame, UPenn Wharton, taking a gap year to chase Rio, and why his parents never made winning the point. Ari also breaks down the mental framework he now teaches athletes: purpose, honesty, consistency, forgiveness, and learning to treat wins and losses as data. This is a conversation about fencing, family, pressure, and becoming the person behind the performance.

Jeff Pelaccio on Losing His Mom, Corporate Layoffs, AI & Reinvention

with Jeff Pelaccio

Viewer discretion is advised. This episode includes conversations about childhood loss, Alzheimer’s, physical discipline, career instability, and difficult family memories.

Jeff Pelaccio’s foundation was shaped early by loss, loyalty, and the need to keep moving. His mother died the day before his fifth birthday. His father, a union welder, developed early-onset Alzheimer’s when Jeff was still a kid. And the New York Italian family around him modeled work ethic, loyalty, survival, and showing up when life gets hard.

In this episode of Hidden Foundations, Kendall and Jeff trace how those early patterns followed him into corporate America, where nine involuntary career transitions taught him that no job is ever fully safe. Their conversation moves through reinvention, podcasting, leadership, stoicism, meditation, AI, deep work, interviewing, mentorship, and why resilience often begins with learning what you can control and what you have to release.
