“I’ve enjoyed finding ways to develop a custom experience for buyers, whether it is designing a home to be built or designing a process and technology for buyers to utilize in their home search,” he says. “In real estate, because no two homes are the same, it allows for endless opportunities and helping people pursue those opportunities is something that continues to fuel and fulfill me.”
