About William
I am an experienced and dedicated realtor who specializes in helping people achieve their real estate goals. I’ve been a resident of Delaware since 1998. Our state may be small, however, we have a lot to offer from urban locations, to sprawling suburbs, to quiet and quaint beach towns. I am an alumnus of Temple University in Philadelphia, PA and I hold a bachelor’s degree in finance. My unique combination of real estate and finance can help you navigate the housing industry.
With over 20 years’ experience, I continually strive to build initial and lasting relationships with those I serve. I am very confident that my knowledge of the local housing markets will help you sell your home or purchase the home of your dreams. I look forward to partnering with you.

Bill is amazing!! Hes very knowledgeable, kind, flexible with his time, and always willing to answer any questions big or small. Bill treats your home buying process as if your family. He wants you to get exactly what your looking for and will give you the best pointers. I couldn't have asked for a better realtor.
