He has been very ambitious about opening this store, and it’s been great to watch him be so eager and passionate. If anyone in Dubuque knows the lumber business, it’s Mark! He convinced me to come along when he said, “Imagine when in a couple years we can look at a successful, new, local lumberyard and say, ‘We did this together!’” That’s when I was sold!”
