Q&A With John

What would be impossible for you to give up
Time with my son and the St Louis Cardinals.

Where is home?
I’m from St. Louis and have a large family that still lives there. But, home is Austin with my son and career.

What’s your favorite family tradition?
My son and I are very close with my family in St Louis and we try to see them at least five times a year. Each summer, my parents rent a large house at a cool locale (like Martha’s Vineyard or St. Simons Island) and my extended family all get together with lots of kids running around. We look forward to that trip all year long.
