Born in Alaska, Nick began crabbing at the age of 13, oftentimes leaving school and heading straight for his father's boat to help the crew, according to his Discovery bio. In 2013, he began starring on Deadliest Catch, ultimately appearing on 78 episodes throughout seven years.

"Nick is known for his witty quips, working through the pain, and not stopping the job until it's done," his bio reads. "He has also kept the boat running through all kinds of mechanical issues, manufacturing quick fixes on the fly. Nick has a wealth of fishing experience…the epitome of a true crabber."

During season 13 of the show, Nick entered rehab after battling an addiction to alcohol and drugs. "My life went from Bering Sea badass to full blown junkie very rapidly," he wrote in an essay for Chosen magazine. "I was broken and soulless. I was living without any hope of happiness. All I wanted was to stay loaded. Every bit of happiness stripped away by a powerful, cunning, and baffling disease."

At his lowest, he was drinking "a half a gallon of vodka, shooting two grams of heroin and one gram of meth every day," he wrote, noting he had overdosed three times before seeking help in November 2016.

However, once sober, he took pride in being an advocate and helping others get clean. "The greatest thing about my recovery is that I can change someone's life just by talking about my addiction and recovery," he explained. "As I thrive in my recovery my world begins to make sense...When I look at my life and feel at peace with the changes I've made, that's recovery."
