Zaslow guest-starred on a number of other television shows and soap operas, including Barnaby Jones, The Love Boat, and Law & Order.

In the episode "The Man Trap," the series' September 8, 1966 premiere of Star Trek, he played Crewman Darnell, the first Starship Enterprise crew member to be killed off.

Zaslow received multiple Daytime Emmy nominations (and won once) for his work in the role, and continually appeared on both critics' and fans' lists of favorite soap opera performers.

(There are conflicting stories as to whether Zaslow was then fired; there was for some time a legal action against Guiding Light and sponsor Procter & Gamble, which was eventually settled.)

It was some time before Zaslow was diagnosed with amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease (it was first thought he had suffered a stroke[1]).

Hufford founded ZazAngels, a foundation that seeks to raise funds in order to find a cure for Lou Gehrig's disease.
