American casting director who worked alongside Junie Lowry-Johnson on Deep Space Nine, Voyager and Enterprise, handling much of the weekly guest casting for the later Berman-era series.
Ron Surma joined the Star Trek casting office in the early 1990s as an associate of Junie Lowry-Johnson and went on to share the casting credit with her.
He worked on Star Trek: Deep Space Nine and Star Trek: Voyager and remained through all four seasons of Star Trek: Enterprise, where the two were jointly credited for assembling the crew of the NX-01.
Much of his work lay in filling the many guest and recurring alien roles each week, parts that often called for actors able to perform under heavy prosthetic make-up.
