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.
