Brian Rihner and Dave Kester started their first business venture together in 1995. Now, 28 years later, they reunite again to talk about their passions of math, life, hope, and faith, and how they are all connected. They provided a probing and analytic perspective to consider the beauty, wonder and timeless treasures of these topics and how they have the power to draw us closer together.
