As an ensign, Garrovick served as a security officer aboard the Federation starship USS Enterprise under Captain James T. Kirk, along with Ensign Rizzo, a friend from Starfleet Academy. In 2268, Garrovick encountered the same dikironium cloud creature that killed his father and two hundred members of the USS Farragut crew years earlier, in 2257. Garrovick hesitated before shooting the creature, which then killed two other security officers. Garrovick suffered intense guilt for his inaction, but it was later determined phaser fire had no effect on the creature. Garrovick redeemed himself by setting a trap for the creature with Captain Kirk and successfully destroying it. (TOS episode: "Obsession")
According to one account, by the early 2270s Garrovick had reached the rank of Lieutenant, and requested transfer back to the Enterprise after Admiral Kirk took command of the ship again. Garrovick worked under Security Chief Pavel Chekov, but was killed on Cragon V in an unsuccessful attempt to take a Klingon plasma grenade away from a young boy who had picked it up, and who was also killed when the grenade went off.

According to another account, by 2279 Garrovick reached the rank of Commander and served as first officer of the USS Gagarin under Captain Gralev.

Garrovick spent the next eight years in a prison facility on planet Pao'la, working as a slave laborer in that world's dilithium mines. He was finally rescued in 2287 by Captain Kirk, with the assistance of Klingon Captain Koloth. (TOS novel: In the Name of Honor)
