Of his 1980 performance in John O'Keefe's All Night Long, Sarasota Herald-Tribune art reviewer Marcia Corbino wrote that Grodénchik was an intriguing actor who had "an enchanting, mobile comic face on which aberrant emotions flicker, spread, retreat, retrench and explode with a single instant.

Grodénchik was instead hired to play the "Pit Boss" in charge of the gambling at Quark's Bar in the pilot episode, and his role gradually expanded from there.

[5] Shimerman and Grodénchik appeared on opposite teams on the short-lived British science fiction game show Space Cadets in 1997.

Grodénchik played Sovak and Par Lenor in Star Trek: The Next Generation episodes "Captain's Holiday" and "The Perfect Mate", respectively.

In summer 2018, Grodénchik reprised the roles of Rom and Sovak in Star Trek Online's Deep Space Nine-themed expansion pack Victory Is Life.
