About Madison

Gateway Realty Group is a real estate team with Berkshire Hathaway HomeServices Select Properties, based in O'Fallon and working across St. Charles County, St. Louis County, and the greater St. Louis area. In 2025 the team closed 101 transactions and $56.4 million in sales volume, counting every buyer and seller side represented. Its agents represent first-time buyers, move-up buyers, sellers, and investors, and clients have left more than 140 five-star reviews on Google. New construction is a particular strength. Several Gateway Realty Group agents worked directly for homebuilders before joining the team, so they understand how builder contracts, lot premiums, design center pricing, and construction timelines actually work. That experience matters most in the moments when a builder's on-site agent is representing the builder rather than the buyer. The team also handles relocation for families moving to the St. Louis area from out of state, competitive multiple-offer situations, and luxury and waterfront properties including homes on Lake St. Louis. Gateway Realty Group markets its listings with two full-time marketing staff and a network of specialists, covering professional photography, video, and digital campaigns for custom, high-end, and one-of-a-kind homes. Listing strategy, pricing, and negotiation are handled in house. The team's market area covers O'Fallon, St. Peters, St. Charles, Wentzville, Cottleville, Lake St. Louis, Dardenne Prairie, Chesterfield, Wildwood, Kirkwood, and Webster Groves, spanning the Fort Zumwalt, Francis Howell, and Wentzville school districts. Buyers and sellers often arrive already familiar with the area through Living St. Louis, the YouTube channel hosted by broker-salesperson Jacob Peistrup, which publishes neighborhood guides, market updates, and new construction tours across the region.

I was referred to Candy via my mortgage company, and I am so glad that those stars aligned

I was referred to Candy via my mortgage company, and I am so glad that those stars aligned. Candy is a true partner in the house hunting and house purchasing process. She is extremely patient and thorough in finding homes to search and calling out the pros & cons of each. Once a home is found, Candy handles all of the administrative pieces from start to finish, and keeps the buyer looped in on significant milestones. When a decision is required, Candy presents the information in a digestible and easy to understand format. She is compassionate and really took the time to find the perfect home for my daughter and I. I would have no hesitations in recommending Candy to family, friends, and colleagues -- and I look forward to being able to do so in the near future.

Working with Kellie at Gateway Realty Group was one of the best decisions we made during our move fr

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!
