About William

My passion for real estate began in 2005 with purchase of my first home. That passion grew until I decided to make the leap to real estate from social services, which has allowed me to continue helping others. I am honed in on the needs and goals of my clients, giving peace of mind to buyers and sellers that every detail of transaction will be handled professionally. As one of the top producing agents in the Century 21 system in PA, I believe consistent training and education are key to staying ahead of the competition. I am a native of the Philadelphia area and have extensive knowledge of the city, surrounding counties, and school districts. I'm a bit of a foodie and like to explore new restaurants. I'm also an avid Philadelphia sports fan and enjoys all things lacrosse. But at the end of the day there's nothing better than spending time with my wife and 2 kids.
