About

Gateway Realty Group is a real estate team at Berkshire Hathaway HomeServices Select Properties in O'Fallon, Missouri. We help buyers, sellers and investors throughout St. Charles County, St. Louis County, St. Louis City and surrounding communities. Our local agents and dedicated marketing team help you understand your options and plan each step of your move.

SELLING YOUR HOME

A unique, custom or luxury home needs a marketing plan built around what makes it distinctive. We combine pricing guidance with professional photography, video, drone imagery and targeted promotion. We guide sellers through preparation, offers, inspections and negotiations, including those selling waterfront homes or properties with land and acreage.

BUYING AND RELOCATING TO ST. LOUIS

Whether you're buying your first home or moving from out of state, we help you compare neighborhoods, home prices and property types based on your budget, priorities and timeline. Our Living St. Louis YouTube channel and LivingStLouisMO.com offer neighborhood guides, home tours and new-construction resources to help you get to know the area before you arrive.

OFF-MARKET HOMES AND NEW CONSTRUCTION

We help buyers explore off-market and pre-MLS opportunities alongside publicly listed homes. Availability varies with your needs and the market. For sellers, we help compare an off-market sale with a public listing when privacy or timing matters. Buying new construction? We help you compare builders and communities and navigate contracts, options, inspections and closing timelines.

WATERFRONT HOMES AND COORDINATED MOVES

We help buyers and sellers with waterfront properties, including in Lake St. Louis, and help buyers evaluate lake access and community rules. If you're upsizing, downsizing or selling before moving into a newly built home, we help coordinate both transactions, contingencies and closing dates.

We had the pleasure of working with Kellie, and we couldnt be happier with our experience! She was incredible to work with from start to finish. She took the time to truly understand what we were looking for and always had our best interests at heart. When challenges came up, she went to bat for us and advocated on our behalf every step of the way.

We absolutely adore Kellie and are so grateful for everything she did to help us find our home. We highly recommend her to anyone looking to buy or sell a house—youll be in the best hands!

Working with Kellie at Gateway Realty Group was one of the best decisions we made during our move from Chicago to Kirkwood. Purchasing a home from out of town can be overwhelming, but Kellie made the entire process feel seamless.

She was incredibly communicative, responsive, and always kept us informed every step of the way. Since we couldn’t always be in town, she truly became our boots on the ground, checking on things, coordinating details, and making sure nothing fell through the cracks. She worked around our schedule whenever we were able to come into town and made every visit as productive as possible.

Her local knowledge of Kirkwood and the surrounding area was invaluable, and her guidance gave us confidence throughout the entire home-buying process. We genuinely couldn’t have done this move without her dedication, expertise, and willingness to go above and beyond.

If you’re looking for a realtor who is knowledgeable, trustworthy, and truly invested in her clients, I can’t recommend Kellie and Gateway Realty Group highly enough. Thank you for making our transition to Missouri such a positive experience!
