Dave joined WJLA in 1990 after being chosen as one of the winners of the station’s Weekend Weathercaster Search, a live audition of prospective meteorologists during the February sweeps that year. Twenty years later, Dave continues as a weekend weather forecaster for tbd/News Channel 8 and WJLA-ABC7.

Besides his weather forecasting duties, Dave serves as the Senior Television Specialist with the Prince George's County Public Schools' Office of Television Resources in Landover, Maryland. Over the past twenty-five years, he has written, produced, and hosted four award-winning science programs that have aired on cable television: "Give Science A Hand", a hands-on approach to science aimed at elementary school students; "Science Bowl", an interscholastic science game show; "Under the Microscope", a series of staff development programs for elementary teachers that also airs nationwide on PBS stations, and a new series, "Anatomy of a Lesson."

Dave is a cum laude graduate with a B.S. degree from the University of Pittsburgh and has an M.A. degree in school administration and human relations from George Washington University. In 1985, after a teaching career that had spanned fourteen years, including three years as a Peace Corps volunteer in Nairobi, Kenya, Dave was selected as Maryland's Teacher in Space candidate. He was one of 100 teachers chosen from the 40,000 applicants nationwide to vie for a flight aboard the space shuttle Challenger.

Dave has received a number of awards, including the CINE Golden Eagle, for his work as a science teacher, a television host and producer, and a space educator. He continues to produce and host public television programs with the Office of Television and Web Resources in Prince George's County and is in his eighth season as moderator of “It’s Academic,” a high school quiz program that airs on WJZ-TV in Baltimore
