  • My Story

    A Unique Background. Unique Client Service.

    Stumbling into her super power

    Katie feels like she stumbled into her super power. She got her real estate license because she had the time and interest, but not the intention of working in the field. Instead, she helped a couple of very close friends to buy or sell homes and thought that would be it.


    But her close friends and clients kept referring more and more people to Katie. In under 4 years, she became a top-producing agent without spending a dollar on marketing or making a single sales call. During that time, Katie realized that her ‘hobby’ had become not only a lucrative business, but also the single best way for her to make a positive impact on the world around her.

    Making an impact

    Every aspect of her unique professional background that includes business strategy, marketing, business ownership, contract negotiations, and personnel management is brought to bear for each of her real estate clients. Katie gets the opportunity to learn about her clients hopes and dreams and to help them achieve those goals through real estate. She continues to run her business based entirely on the referrals of current and former clients. Katie deeply appreciates that support and is so proud of the impact she’s able to make in the lives of her clients.

    Experience and education

    Katie’s professional background and education is in business management – specifically brand strategy and marketing. Katie co-owned and operated Biker Barre, a boutique fitness studio on Capitol Hill, until 2019 when Katie happily sold her shares to her business partner in order to focus on real estate. Prior to Biker Barre she worked in advertising for many years advising clients such as Proctor & Gamble, Bank of America, and Volkswagen Group of America. Katie holds a BA and MBA from the University of Michigan. A devoted Michigan alum, Katie has also served as the President of the Washington, DC chapter of the Ross School of Business Alumni Association.

    Took the Stress Out of It

    "Working with Katie was great! She is extremely knowledgeable about the DC/MD market and had some great insight on a variety of neighborhoods in different areas. When we would walk through homes, she had a great eye and would point things out that we never would have noticed on our own. She was dedicated to helping us and was always available to answer any questions we had and always made us feel like a priority. Buying a house is a stressful process, but Katie really took the stress out of it for us. We had 100% confidence that everything was handled perfectly. If you are thinking of buying a home, do yourself a favor and hire Katie immediately!" - Jess and John B.

    Knows the Market

    "Katie stepped in and told me that a house I was about to put an offer in on was way overpriced. Thanks to her intervention I ended up in a beautiful, affordable apartment in a neighborhood I love. And the house I was previously thinking about had its price dropped by 30K the week after her very timely intervention!" - Martha G.

    Great for First-Time Home Buyers

    “My fiancé and I had been looking for our dream home for a few months. Nothing was “it” - we even had two offers fall through. After the second failed offer, we decided to “break-up” with our original agent and found Katie. She was a complete 180 in our home search and buying experience! Incredibly professional, knowledgeable, and just cool to be around. Our dream home ended up being the first one we looked at with Katie and she sealed the deal. I would definitely recommend her for anyone looking for a home, but especially for first-time home buyers. She’s awesome!” - Ashleigh and Brian
