“Katie listed and sold our home. From the beginning stages through to the end she represented us with authority and grace. Her keen eye style helped us organize our home in preparation listing. The listing package had a fantastic presentation and photos including aerial drone photos. Her comps were accurate and helped us get near asking price after minimal days on the market. Her experience and knowledge kept the sale on track while dealing with an overly aggressive buyer's agent on the other side. Yes, I would use her again!“ - Loren
An Ohio native, Katie attended Ohio Wesleyan University as an International Business major. Upon graduating, she became a logistics and marketing specialist for international commodities firm, Marc Rich and then later Louis Dreyfus Corp. Katie spent the next few years traveling the world, making stops in Moscow, Istanbul, Bangkok and Europe.
In 1998, Katie, her husband, and their 2 children made the move from the city to the suburbs, settling in Wilton, CT. They were immediately captivated by the town's New England charm and great schools. Katie became a substitute teacher and very heavily involved in the community. She volunteered at the Wilton Children’s Theatre and PTA, and served as an Elder and a Deacon in the Wilton Presbyterian Church.
No stranger to reinventing herself, Katie left teaching to venture into real estate. Her ability to dream big and obsess about opportunities has established her as a respected agent in Fairfield County. She even had a moment in the spotlight when she represented both the buyer and seller in a deal that was featured on HGTV’s Property Brothers.

Katie’s ability to adapt and thrive make her an asset in the ever-changing real estate market.
