I love where I live and love what I do! Helping people transition from one home to the next is both exciting and challenging and I wouldn’t have it any other way. As far as I’m concerned, my clients are more than real estate transactions; they’re people, and taking good care of them and what’s probably their largest personal asset is the most important part of my job. My goal is to make the whole process educational, fun, stress-free and as positive as possible.

In my prior career as a teacher, I taught fifth grade and then Kindergarten. After taking a few years off to stay home and raise my own children, I joined Keller Williams in 2007. With the help of KW training and education, over time I became one of the top five producers in my office. Now, as an Associate Broker, I participate actively in both a leadership role as well as presenting in-house training programs. I believe in sharing my knowledge and experience with my colleagues so that we can all grow our businesses and achieve our personal goals.
