About me

Communication. Analysis. Negotiation. Trust. These four skills are necessary to successfully work with my clients. I began my career as a financial analyst and then moved into the field of marketing after business school. I am an accomplished marketing professional with years of experience developing and leading strong corporate brands. It is combinations of these skills that enable me to be a highly effective real estate agent and professional advisor to my clients. As a lifelong resident of Bronxville and a graduate of the Bronxville School, I have extensive knowledge of the village and the surrounding areas.  I have lived in the Bronxville area for over 35 years and have raised a family as well as extensively volunteered in the school and community. My business skills combined with my extensive knowledge of the area will benefit both buyers and sellers in making the best decisions when purchasing or listing a home.   More
