Hertzler lives in the Finger Lakes region of New York where he was a lecturer at Cornell University's theater department, and has been active in the area's regional politics, as well as writing a screenplay.
Hertzler was born in Savannah, Georgia.
His parents were from Port Royal, Pennsylvania, and his family is descended from German-speaking Amish families.
His father John G. Hertzler served in the U.S. Air Force, and his mother Eleanor Frances Beaver Hertzler was a Latin and French teacher.
His family lived in cities around the world including: St. Joseph, Missouri; El Paso, Texas; and Casablanca in Morocco.
He grew up mostly in the Washington, D.C. area, and attended Bucknell University, playing linebacker on their football squad.
While there, he got into acting when the drama department recruited him for a production of Marat/Sade as they were looking for a big guy for one of the roles.
His first major television role was in the 1990s series Zorro as Alcalde Ignacio De Soto, the antagonist character who replaces Ramone as the Alcalde (Mayor) of Los Angeles in the third and fourth seasons.
The show was filmed in a studio lot outside of Madrid, Spain, and was broadcast on The Family Channel.
He was also involved in a television movie called Treasure Island: The Adventure Begins where he played a pirate called Black Dog.
Treasure Island was broadcast to go along with a promotion for the casino resort in Las Vegas.
Hertzler's first involvement in Star Trek: Deep Space Nine was in the series' pilot episode "Emissary" as the Vulcan captain of the Federation starship Saratoga.
In an interview with Startrek.com, Hertzler said he had worked with Patrick Stewart at the Paramount Studios lot where Stewart ran some Shakespeare workshops.
He would later audition for DS9 multiple times, but did not receive any roles.
He was at the Paramount Studios auditioning for another series when DS9 casting director Ron Surma had him read for Klingon General Martok.
At first, Hertzler portrayed Martok as a mild-mannered Klingon, but when he was asked to make him angrier, he picked up a chair and threw it into a wall.
The chair's leg stuck briefly and he said he had also inadvertently ripped his thumbnail causing it to bleed, but it had impressed the auditors and he landed the part.
Martok debuted in the season 4 premiere "The Way of the Warrior" followed by the season 5 premiere "Apocalypse Rising".
His character was originally a changeling (shapeshifter) Dominion impostor.
Hertzler said the writers chose Martok to be the changeling, because they thought that making the Klingon Chancellor Gowron to be an imposter was "too pat or too easy."
After the Martok changeling was killed in the episode Apocalypse Rising, the writers then brought in the real Martok as a recurring character starting in season 5, during which he portrayed a one-eyed Klingon.
He would play Martok for three seasons including the finale, by which time he had replaced Gowron as the leader of the Klingon Empire.
Hertzler describes the part as an actor's dream because of its physicality and range.
The character has been involved in many aspects of Deep Space Nine including frequently interacting with Worf.
Hertzler played other characters in DS9, including a changeling named Laas, in the episode "Chimera", who interacts with main character Odo.
In an interview with Little Review, Hertzler said that he was concerned he would be recognized as Martok despite the makeup and character change, but it worked out okay.
