About Grace

Hi! I’m Grace O’Brien, a licensed real estate broker and Realtor with Gardner Real Estate Group in Portland, Maine’s Arts District. I launched my real estate career in 2018 after more than 20 years in hospitality, bringing a service-first mindset and a steady, results-driven approach to every transaction.

I’ve helped hundreds of clients across Maine buy, sell, and invest in residential, commercial and raw land properties. My business is built on relationships, repeat clients, and referrals—proof of my commitment to market expertise, clear communication, and highly personal service.

I started with buyer representation, specializing in first-time homebuyers and guiding them through complex transactions with clarity and confidence. Today, I support clients at every stage—upsizing, downsizing, investing, and selling strategically.

With deep local knowledge and a hands-on, client-first approach, I help my clients make informed decisions—from the first showing to the final signature walking away happy with keys in hand.

I also bring added perspective through my close connection to the building and design industry—my husband, Mat O’Brien, owns a Portland-based design/build company. For clients considering renovations or custom work, this means access to trusted resources and practical insight on construction, remodeling, and design.

I live in Falmouth, Maine with my husband, our two daughters and our rescue dog. I’m proud to be actively involved in the Southern Maine community. I’d be honored to help you reach your real estate goals with confidence.
