Katie is a proud and valued member of The Bogard NY Team, an award-winning team recognized for excellence in residential real estate across New York City. Respected by both clients and industry peers, the team is known for its expertise, integrity, and results-driven approach.

Katie brings a unique combination of diligence, empathy, and precision to every transaction. Her strong work ethic and meticulous attention to detail, paired with a genuine desire to help others, allow her to build lasting relationships with clients while navigating the complexities of the buying and selling process. A thoughtful listener and skilled negotiator, Katie is deeply committed to understanding her clients’ goals and advocating on their behalf every step of the way. Specializing in both resale and new development properties throughout Brooklyn and Manhattan, Katie has played a key role in numerous building sellouts while representing developers. As part of The Bogard NY Team, she contributes to their consistent recognition—including being named one of the Top 50 New Development Brokers in NYC by The Real Deal in 2023, and consistently ranking as the top-producing team at SERHANT. for monthly volume.

Originally from Westminster, MD, Katie has a bachelor’s degree in Physical Education from Hofstra University and holds a distinguished background in athletics. Before Katie’s real estate career, she spent a decade coaching in Division 1 women’s lacrosse. Katie most recently served as the defensive coordinator for the University of Southern California and helped guide the program to a Conference Championship and a #6 National Ranking. In addition, Katie was a member of the United States National Lacrosse Team from 2010-2015 and competed in the Women’s Professional Lacrosse League from 2018-2021. Heralded as one of the top defensive lacrosse players in the nation, Katie has asserted her ambition and competitive edge to the real estate profession.

Katie currently lives in Williamsburg, Brooklyn with her wife and terrier mix rescue dog, Danny. In her spare time, she loves walking through the parks of the city with her dog, going to the local Greenmarket, and exploring new restaurants. She’s an advocate for animals and loves being a foster with local NYC Rescues along with actively volunteering at the NYCACC. Her love for dogs, sports, and food ignites her passion for city life as a proud Brooklyn resident.
