William was a member of the Delaware Valley High School Class of 1978. A recent immigrant from Mexico, and speaking little to no English upon arriving in his adopted country, Bill worked industriously to master his new language while, at the same time, completing all the requirements of the high school curriculum. A natural athlete, Bill excelled in scholastic sports, primarily soccer and baseball, two sports in which he distinguished himself with offensive and defensive skills noteworthy enough to rank him as a standout player in both.  He was recognized by his class as Most Athletic.

His professional career began as a car salesman.  His outgoing personality and unfailing  good nature were assets that enabled him to  overcome his struggles with the English language, as evidenced by his continuous promotions.   His drive, enthusiasm, and work ethic provided the opportunity for him to become the successor of the dealership for which he worked.  Over time, he developed the Rosado Group of Dealerships, comprised of four new car franchises, employing over 300 people. Through his businesses, he supports numerous communities, leagues, and charities, including the United Way and the Center for Childhood Disabilities. 

From humble beginnings, Bill is the embodiment of the true American success story. A man of integrity and faith, he is both respected and admired.
