Kasia McCormick

Smart. Analytical. Fierce negotiator. Loyal advocate. These are just a few of the qualities clients consistently use to describe Kasia—and they’re backed not just by words, but by results.

With over $30 million in annual individual sales year after year, Kasia has become a trusted advisor to Houston's most discerning clients across Houston’s most prestigious neighborhoods—including Memorial, West U, Briargrove, The Heights, Oak Forest/Garden Oaks, Spring Branch, and The Woodlands.

But beyond the numbers, Kasia brings something truly unique: a global perspective, an Ivy League education, and extensive professional experience negotiating for the U.S Government. A former U.S. diplomat with degrees from Columbia University and University of Illinois, she served in the Peace Corps in Senegal and spent seven years in Washington, D.C. as a Presidential Management Fellow with the U.S. Department of State. Her diplomatic experience taught her how to navigate complex negotiations with calm and clarity—skills she now brings to the closing table.

Since settling in Houston in 2009, Kasia has been fully immersed in the city. She and her husband are raising their young children in the inner Loop, where she’s actively engaged with schools and civic life. Her clients benefit not only from her extensive market knowledge and sharp financial acumen but also from her firsthand understanding of neighborhoods, schools, and lifestyle fit.

Kasia is as warm and personable as she is strategic and informed. She’s known for being a clear communicator, deeply responsive, and incredibly patient—especially when helping families make big transitions. As one client put it: “Whether buying or selling, she brings unmatched professionalism, market expertise, and a calm confidence that makes even the most stressful moments feel manageable. What sets Kasia apart is her deep knowledge of the market and an intuitive understanding of what we need even before we do. She has always been honest, responsive, and fiercely dedicated to our best interests. Every detail is handled with care and precision, and she consistently goes above and beyond. Thanks to Kasia, we've made smart investments, navigated tricky negotiations, and found homes that have brought real joy to our family. We're deeply grateful for the years of partnership and trust, and we recommend her wholeheartedly to anyone looking for a top-tier real estate professional."

"Kasia exceeded all expectations in the purchase of our new home. She led us each step of the way through the offer and negotiation stages to close with ease. Her detail oriented nature and communicative nature made the process stress free. We couldn’t recommend her more highly."

"Kasia exceeded all expectations representing us in the sale of our home. She has deep and detailed market knowledge which I believe greatly contributed to our success in selling quickly. She went above and beyond and communicated every step of the way. I highly recommend her as a real estate professional."

"Kasia is simply the best realtor I have ever worked with, and I cannot speak highly enough of her. Her level of research, attention to detail, level of responsiveness, and knowledge of the market are just spectacular. On top of that, she is a strategic thinker, keeping two steps ahead of what the market is doing, proactively working with you on your search strategy, and helping you to position to find and close on that perfect property for you. I also can't say enough good things about her "intangibles" - the warmth and friendliness of her personality, her level of professionalism and respect, and her understanding of the challenges of the home-buying process from both a financial/practical and a personal/emotional standpoint. A person who chooses to work with Kasia knows that they have a teammate, partner, and guide who will look after their interests, support them through the process with incredible energy, and will be with them every step of the way."

"Kasia did a phenomenal job selling our home. She provided specific, strategic advice which led to a smooth, quick, successful sale process. It was comforting to be able to fully entrust her with the sale, knowing that she would handle every detail with precision. She successfully marketed our house to create excitement and buzz, and then negotiated our multiple offer situation perfectly. We had the utmost confidence that she would represent us well, and throughout the process, we were impressed by her professionalism and market knowledge. We have already recommended her to family and friends."

"Kasia was truly incredible: always available, knowledgeable, and frankly friendly! She patiently showed us many rentals, prior to us deciding to buy. When the perfect home came onto the market for sale, she quickly arranged a showing. We had an offer in that night and it was accepted a day later with little negotiation! She helped us every step of the way thereafter, even after closing. We were first time home buyers, and we had a wonderful experience with Kasia."

"Kasia is simply the best of the best. Her skills and capabilities from a technical/commercial perspective are extraordinary. When it came to selling our house, her skills in evaluating pricing/comps; preparing the property (and owners) for sale; marketing and building interest among purchasers; negotiating with purchasers and drafting contracts; managing the closing process and post-closing follow-up and paperwork - all of it was flawless. Kasia further distinguishes herself in the interpersonal and emotional aspects of the business. This was one of the biggest decisions and moves that our family will make and having someone who is smart, empathetic, level-headed, and emotionally intelligent was just incredibly important for us. To any individual or family who is considering working with Kasia, I would say "Do yourself an enormous favor and say 'YES!'"

"Kasia was an incredible realtor. She is extremely detail-oriented, thorough and also a joy to work with. We appreciated her responsiveness and her ability to think outside the box. Due to Kasia's diligence and recommendations we were able to uncover some significant issues during our inspection which she helped us work through. She is also incredibly resourceful and provided excellent advice on all aspects of the purchasing process. I would never use anyone other than Kasia if selling or purchasing a home!"
