The Entrepreneur DNA

In this episode, I sit down with Mark Vincent Fanzler, who went from carpenter to senior corporate executive, walked away from burnout, and built a vertically integrated commercial real estate empire operating across multiple states. We talk about the power of elite rooms, the vision he had at 17 that shaped his future, how one intentional conversation turned into a $120M opportunity, and why thinking bigger is the only way to win in business. This is a masterclass in community, commercial scale, and betting on yourself when no one else believes you deserve it.

In this episode, I sit down with John Curri, who built and sold a 160-location cell phone franchise before he turned 28, only to get humbled when he jumped into real estate with a god complex and learned some hard lessons about leverage, markets, and ego. We break down how he started with a $2,500 credit card, why execution matters more than capital, what really happens after a big exit, why most people shouldn’t own homes, and how he’s now building a national concierge-style property management company designed to eliminate the biggest headaches homeowners face. This one is about grit, humility, scaling smart, and building legacy over ego.

About John Curri

John Curri is a serial entrepreneur, real estate investor, and business builder who scaled a 160-location cell phone franchise across 38 states before exiting in his twenties. Since then, he has built and sold multiple service-based businesses and grown a diversified real estate portfolio including residential, commercial, and investment properties.

John is currently focused on scaling innovative service businesses, including One Call Management, a concierge-style property management company designed to simplify home and investment property ownership through a single point of contact for maintenance, repairs, and facilities management.

Most salespeople lose deals long before they ever ask for the close.

In this episode of The Entrepreneur DNA, I sit down with Wesleyne Whitaker — a former chemist turned sales strategist — to break down the science and psychology behind consistent revenue. We dive into why scripts are hurting more than helping, why the fortune truly is in the follow-up, and how fear of rejection silently sabotages even talented entrepreneurs.

Wesleyne shares how she transitioned from working in a chemistry lab to scaling a struggling sales territory from $50,000 to $500,000 in just one year — without formal sales training. What changed? She stopped focusing on tactics alone and mastered the mindset behind selling.

About Wesleyne:

Wesleyne Whittaker is the creator of BELIEF Selling, a sales strategist, international speaker,
and the founder of Transformed Sales. A "recovering chemist" turned top-performing sales
leader; she built her career leading field sales teams in complex, technical industries before
launching her own consulting firm. Today she equips companies and sales professionals to break
internal barriers, align mindset with skillsets, and create customer-centric strategies that drive
measurable results.

Drawing more than fifteen years of experience across manufacturing, distribution, and global
markets, Wesleyne blends data-driven sales expertise with deep empathy for the human side
leadership. She coaches leaders to see the world through their employees eyes and challenges
conventional wisdom that prioritizes tactics over belief.

In this episode, I sit down with sustainability expert Belen Benitez to talk about something most entrepreneurs completely ignore while scaling their businesses: protecting the downside. We break down why sustainability has nothing to do with being “woke” or environmental politics and everything to do with building a business that can survive uncertainty, leadership changes, labor shortages, pandemics, and economic chaos. Belen explains how fast growth without systems, culture, policies, and risk planning eventually leads to burnout, furloughs, and failure, and why slowing down strategically actually creates more money over a longer runway. This conversation challenged how I think about growth, risk, and long-term success, and it will do the same for any founder who wants to build something that truly lasts.

About Belen:

Belen Benitez is a sustainability strategist and founder of Baseline SD, a minority-owned consulting firm that helps companies turn sustainability into a competitive advantage. With nearly two decades of experience, she works with startups through global enterprises to build resilient, scalable business models that align growth, profitability, and long-term impact. Holding a master’s degree in Sustainability from Harvard University, Belen has advised C-suite leaders and boards at organizations including Kelly Services, Holcim, UNDP, and Astrix Technology Group. Born in Ecuador and based in Miami, she brings a global perspective shaped by work across 18+ countries, helping founders and executives scale sustainably by integrating purpose, governance, and performance into their core business strategy.
