With a goal to create a “world where every child with complex medical needs lives their best life” by expanding the accessibility of Ranken Jordan services, Dryden says the best advice he ever received was to “not chase titles or money and to instead focus on who I would be working for and the type of work I would be doing—and then outwork everyone… If you do those things, success tends to follow.”

Walsh’s experience in the military informs his “troops eat first” work ethic—one that literally could have translated into his childhood dream job of chef. Fast-forward to today, and Walsh says that mentality still rings true. “Take care of your troops first. They will always take care of you.”
