Andy Tyler

Tile, Course Lead


Andy spent the majority of his career in sales, 15 of those years working for the wholesale division of Wayne Tile. Although he loved his job and the company, he felt God had another plan, which lead him to launch an agriculture start-up with a partner in Haiti. Unfortunately, Covid derailed the launch, leading to an unexpected year of homeschooling, leading youth, and working at a local farm. Little did he know, his previous boss at Wayne tile would connect him to what he’s doing now at SHM: spearheading Workmanship’s tile course. We believe the Lord’s timing was perfect for Andy to come on board and help get this new program running.

In Andy’s spare time he loves mountain biking and fishing with his kids and getting out on the water in any way possible.
