Jenn Mueller walks into a room and lights it up, says Mona Spencer, managing broker at John L. Scott Real Estate. “She just makes people have a better day,” Spencer says. That’s because Mueller is big on collaboration and cohesiveness. She’s an advocate for her team members, her clients, and the industry; one of her goals as a board member of Seattle’s Young Professionals Network is to increase member participation in the REALTORS® Political Action Committee. Intrigued by the real estate profession since high school, Mueller was fortunate to find quality mentors. She hasn’t forgotten the help that came her way; now she mentors others—perhaps some future 30 Under 30 honorees.
