  • That One Thing...with Ben Sharf

    This is an episode you do not want to miss. Ben and I met through the boxing gym years ago, and now we’re both part of the Haymakers alumni crew — and trust me, he is a winner in every sense of the word.


    What I’ve admired most is getting to watch Ben live with such intentionality: in his mind, his body, and his career. He’s a founder, a Forbes 30 Under 30 honoree, and truly one of the kindest, most thoughtful humans I know.


    This is someone you’re going to want to learn from.

    Full episode is out now — you do not want to miss it.

  • That One Thing...With Chris Caldwell

    This episode just hits a little different. Like I always say, these conversations keep getting more and more special to me.
    Our next guest, Chris Caldwell, is a business owner, a dad, a coach, a sales trainer, a leader, a proud husband—and a man who continues to evolve in the coolest way, period. Chris has personally impacted me through the Alluviants community I’m part of, and this conversation is packed with so many nuggets of wisdom.


    One of the most powerful themes? Taking responsibility for how you interact with other human beings. Full stop.


    You do not want to miss this one. Chris is a special dude, and this episode is something I know will stay with you long after you listen.

  • That One Thing...with Ed Lees (My Uncle)

    While this podcast always means the world to me, getting to sit down with family hits in a whole different way.


    This next episode is with my uncle — someone I’ve known my entire life, but got to truly know in a new way through this conversation. He’s a dad of four, has had a successful career, is married to my aunt (and godmother), recently sober, and at 62 is still dreaming, still growing, still becoming.


    His story is a powerful reminder that it is never too late to change your life — if, in his words, you’re willing to “get over yourself.”


    This one is incredibly special. Lots of tears. Come ready. You dont' want to miss this one🎙️🤍

  • That One Thing...With Me and my 2026 Reflections

    These solo episodes are always a little scary for me. It’s easy for me to sit down with someone else, ask the right questions, and help them open up — but being the one who’s fully seen is still a vulnerable place, even for someone who’s generally open.

    This year was a big one for me, and I hope this reflection episode lands with you in a meaningful way. My biggest takeaway — and the thing I’m carrying with me — is this: I will always express my needs and desires clearly and confidently.

    Love you all. Enjoy.

  • That One Thing...with Andrea Giovino

    This episode is going to move you — period. 💥
    I had the absolute privilege of interviewing Andrea, whose story many of you already know. She’s been featured on The View, 60 Minutes, and countless talk shows 📺 — building an incredible career as an author, motivational speaker, and TV personality. ✍️🎤

    But what many don’t know is this: at 36, Andrea was arrested for her involvement in organized crime 🚔 — a moment that shattered her world and forced a complete rebuild from the ground up. Today, she’s a proud grandmother 👵💕 and one of the most genuine, compassionate humans you’ll ever meet. Her mission is simple: use her truth to transform the lives of others. ✨

    This conversation is powerful, raw, and unforgettable. You do not want to miss it. 🎧🔥

    A professional Irish-American boxer, Golden Gloves champ, and Olympic Trials participant—Sean’s drive and discipline are next-level. His story is wild, heartfelt, and so inspiring. The way he’s building a life he’s genuinely proud of? Unreal. 🤝✨

  • That One Thing...With Maurice Barron

    Maurice is one of the wisest people I’ve ever had the honor of speaking with. He’s a proud dad, a boxer, a loving husband, a successful professional, and a kind Irish soul with a heart full of wisdom.

    I met Maurice through the Haymakers community, but I feel truly lucky to have heard his story.

    This episode is about hope, community, navigating grief, and ultimately — joy. It ends with the incredible news of his daughter being cancer-free.

    If you’re looking for inspiration, perspective on grief, and a reminder of the power of community and living without shame, you won’t want to miss this one.

  • That One Thing...with Brett Eaton

    Brett is one of the most inspiring people I’ve had the honor of speaking with. His journey is nothing short of incredible: from fitness instructor turned high-performance coach turned keynote speaker and now published author. Every chapter of his story is filled with lessons about resilience, growth, and what it means to live in true alignment.

    What stands out most about Brett isn’t just his accomplishments—it’s who he is. He’s humble, hilarious, deeply self-aware, and committed to always evolving. He’s someone who doesn’t just talk about transformation, he lives it every day.

    Personally, I walked away from this conversation feeling more grounded, motivated, and grateful—and I know you’ll feel the same. My hope is that this episode encourages you to not only listen, but also lean into Brett’s content and wisdom beyond this podcast. His words and work genuinely change lives.

    If you’ve been needing a reminder that it’s never too late to reinvent yourself, step into your highest potential, or align your actions with your values—this one’s for you.

    🎧 Tune in now—you won’t want to miss it.
