Today’s conversation is a special one. I’m delighted to share my fireside chat with Markel Corporation’s Tom Gayner from our 26th Annual CSIMA Conference. With decades of industry experience, Tom joined us to share insights into how Markel has differentiated itself from others in the insurance industry and the investment approach and philosophies that facilitate its continued growth.   Thomas “Tom” Gayner is the Co-Chief Executive Officer of Markel Corporation. He oversees investing activities for the company, as well as the Markel Ventures’ diverse industrial and service businesses. Tom joined Markel in 1990 to form Markel Gayner Asset Management which provided equity investment counsel for Markel Corporation and outside clients.   In this episode, Tom and I discuss how he went from analyzing Markel to joining the team after its IPO, Markel’s three-engine business model, how Markel Ventures originated, why it’s essential to create an environment that’s supportive of the way you'd like to operate, and so much more!
