About Darien Oliver Gray — Naperville REALTOR® with eXp Realty

D.O.G. stands for Darien Oliver Gray. Like the name suggests: loyal, dependable, and always in your corner.
Darien Oliver Gray, licensed Illinois real estate broker and REALTOR® with eXp Realty

I'm Darien Oliver Gray — Darien, the D.O.G. of Real Estate. I've been a licensed Illinois real estate broker since 2018 and I'm based in Naperville, working with eXp Realty across Chicago and the suburbs.

Before and alongside real estate, I've built a career as a business analyst — so I bring a data-driven, detail-obsessed approach to every search, offer and negotiation. Most of my clients have been first-time buyers and renters, and helping people get their first set of keys is my favorite part of the job. I've also presented at DuPage County's H.O.M.E. DuPage first-time homebuyer education course.

Like any good D.O.G., I'm loyal, persistent and always in your corner. People first — flexible to every client's needs.

“Darien had helped my girlfriend and I purchase our first condo and it was an absolute pleasure to work with such a friendly, knowledgeable realtor the entire time! He was there every step of the way and even followed up after we moved in to make sure everything was still good and that we were still pleased with our purchase... I highly recommend him to anybody buying a house, especially if you're a first time home buyer! You won't regret it.”
