Today, we’re joined by a visionary leader whose career spans four decades of reshaping industries, empowering entrepreneurs, and proving that faith and business can thrive together. Meet John D. Marvin, President and CEO of Texas State Optical (TSO), a name synonymous with trust in eye care across Texas. Under his leadership, TSO has grown into one of the top ten optical retailers in the U.S., generating over $110 million annually while helping young optometrists launch 85+ practices through innovative mentorship and turnkey systems.

But John’s story isn’t just about scaling a legacy brand—it’s about leadership rooted in influence, not authority. A certified John Maxwell speaker and coach, he’s spent decades studying the human side of business, fostering meaningful connections with teams, and guiding professionals to balance bold decision-making with compassion.

From his early days in pharmaceutical sales to revitalizing TSO’s physician-owned model, John’s journey reflects a relentless curiosity. He’s an advocate for lifelong learning, setting yearly reading goals, and reflecting daily on growth—even writing books and hosting his own podcast on practice management.
