Katie Gellenbeck
Engel & Völkers Boston

Katie fell in love with Boston’s Back Bay seventeen years ago and has never left. Her interest in real estate started well before she flipped her first home in Seattle, and has expanded to include both personal and investment properties in Boston and Vermont. She understands that buying or selling a home is a milestone that can build wealth and security.

Katie is recognized as being in the top 1.5% of Real Estate Agents in the U.S. by Real Trends Verified in 2022 and 2023. She is also in the top 500 agents for sales volume in Massachusetts and ranked no. 63 in Boston. She single-handily sold close to  $20 million in 2022 and in 2023. When Katie sets her mind to something, she works tirelessly to achieve it.

Before becoming a Realtor, Katie managed environmental projects. Her exceptional organization skills, attention to detail, and positive attitude made managing complex projects with diverse teams a success. Whether buying or selling a property, Katie brings the same thoughtful and focused approach to helping her clients achieve their goals. Time and again Katie has proven herself as a trustworthy advisor and a tough negotiator.

Katie and her family enjoy life in the city, as well as relaxing at her summer cottage in Vermont. She holds a Master of Science in Natural Resource Management. In her free time, she enjoys playing tennis, getting outside in nature, and exploring new spots around Boston.

    Katie did a great job helping me sell my condo in the Back Bay! She was incredibly communicative, efficient, and organized, and went above and beyond to coordinate stagers, painters, etc. so I didn’t have to go to into the city, as I was no longer living there. She knows the market very well, and the unit sold quickly and at a great price. I highly recommend Katie’s real estate services to anyone in the greater Boston area.

    We worked with Katie to purchase our home. As first time home buyers, Katie was a wealth of knowledge and guided us expertly through every stage of the process. Katie was candid with her advice, extremely responsive and organized, and we fully trusted that she had our best interests in mind at all times. We also appreciated Katie’s recommendations for lenders, attorneys and home inspectors and had a good experience with her entire team. We would absolutely recommend working with Katie!

    We chose Katie after meeting with several other agents. Katie helped us sell our condo and buy a single-family home. The stress levels were high, but Katie took the weight off our shoulders. She assisted us with maximizing our sale price, navigating the market across Boston and wider vicinity, negotiating a fair price, and much more. All of this during a very challenging market. Katie is a professional who takes her job seriously. Without a doubt, Katie receives our highest recommendation.
  • Kevin

    Katie was a great advisor to partner with the sale of our home in Newton. She is a knowledgeable, well connected, and came up with the right plan for us to maximize our return. Once the property was listed, she made the process quick and efficient. When selling an older home, she taught us the value of putting effort and money into the home before it’s listed to yield a more interest in the home and a higher selling price. I would highly recommend her as a home buying or selling agent!
