Career
Hoffman is Jewish. Hoffman debuted in the FIS World Cup at Vancouver in January 2009, placing 25th in the 30 km skiathlon. His first European appearance in the World Cup was at the 2010-2011 season opener in Gällivare, where he placed 31st in the 15 km freestyle, only just missing out on a points finish. He represented the United States at the 2011 World Championships in Oslo, Norway, where he placed 29th in the 15 km classic and 30th in the 50 km freestyle mass start.
2012-2013
Hoffman opened the 2012-2013 season well, placing a career-best 19th in the second stage of the Nordic Opening at Ruka, a 10 km freestyle race.
He went on to place 26th in the final standings of the Ruka Triple. He scored his first top 10 finish two weeks later at Canmore, placing 8th in the 30 km skiathlon.
Hoffman also completed his first Tour de Ski, finishing 46th with a best stage finish of 17th in the final climb. At the 2013 World Championships in Val di Fiemme, Italy, Hoffman improved on his results from two years before.
He finished strong to place 15th in the 15 km freestyle, his best World Championship result to date.
In the 50 km classic mass start he placed 27th after going with an early five-man breakaway. He was the top American in both races. Hoffman narrowly qualified for his first World Cup Final in Falun, Sweden, scoring seven World Cup points at the last opportunity (a 50 km freestyle mass start at Oslo) to move to 47th in the World Cup overall standings as the top 50 qualified for the final weekend.
He eventually finished 48th in the overall World Cup and 36th in the distance World Cup.

Hoffman underwent shoulder surgery in the off-season, hoping to eliminate a recurring shoulder dislocation problem.
