Catherine, a licensed Realtor for over 38 years, a Broker for over 25 years is pleased to now be associated with the office of Diane Silva & Associates, LLC in Portsmouth, NH, a full service boutique real estate office.  Our goal is to provide maximum service, at minimum cost to you, whether selling your current home or buying a new one!

A life long resident of New Hampshire Catherine’s career includes extensive experience and knowledge of the Lakes Region, Seacoast and Manchester areas.  Growing up in the Lakes Region and raising her family in the Manchester area and now living on the Seacoast gives Catherine practical first hand knowledge of three distinct regions and surrounding communities.

Her background experience, working for a local title company on the Seacoast and a hands on education in title research, loan processing, mortgages and the closing process itself, makes her a uniquely qualified agent.  Also, experience as a clerk in the Alton Planning Department gives her the understanding of the ins and outs of land issues when buying and selling your home.
