As a Barrington native, I have extensive knowledge of the Barrington and surrounding markets. As a dedicated, full time real estate professional, it is my promise to go above and beyond expectations to ensure your experience is smooth and enjoyable. A home is one of your largest investments and it is always my goal to provide you with the necessary resources and support you need throughout the buying or selling process. If you are ready to buy or sell or simply starting to consider a move, I can help you find answers to the questions you may have.

My community involvement, along with a true passion for real estate and connecting people with their perfect home or helping them reach their goals to move forward when selling their homes, has been a key to my success. As a lifelong equestrian, active member of local riding clubs, I have unsurpassed insight when it comes to horse properties and area amenities. Whether you would like to purchase or sell an equestrian estate or your very first home, it would be my pleasure to help you!
