Born in Plymouth, Michigan, Gatt played varsity for four years at Detroit Catholic Central High School. He also played in the U.S. Soccer Development Academy for the Michigan Wolves, known now as the Crew SC Academy Wolves.
Club career
Gatt first attracted attention as a Michigan-area youth player when his club competed in a tournament against European academy teams in Switzerland. Through the SuperElite system, the winger was offered trials at 1. FSV Mainz 05 and at SCR Altach and eventually received an offer from the latter club. Gatt proceeded to sign with SC Rheindorf Altach, leaving behind an opportunity to play at Indiana University. Upon his arrival in Austria in the summer of 2010, he immediately joined the first team, and scored 5 goals in 14 matches. On January 12, 2011 it was announced that Gatt had joined Norwegian side Molde, and was among Ole Gunnar Solskjær's first signings as manager together with Davy Claude Angan and Magnus Wolff Eikrem. He made his debut against Sarpsborg 08 on March 18. He scored his first goal on July 30 against Vålerenga. Josh scored his second goal in as many games on August 4 against Start. In the first half of the 2012-season, Gatt scored goals against Strømsgodset, Stabæk and Vålerenga. According to himself he also scored a goal against Sandnes Ulf, but the official statistics count that one to Mattias Moström. On June 29, 2013, during the first half of Molde's home Tippeligaen match against Sarpsborg 08, Gatt seriously injured his knee, ruling him out for the remainder of the season and requiring surgery. Gatt also missed the entire 2014 season. After almost 21 months out injured, Gatt was finally cleared to play again on April 20, 2015. Gatt made his long awaited return for Molde on May 22, 2015, but his lasted only 4 minutes before feeling "....pain and insecurity..." in his knee, resulting in a third operation on the troublesome knee. Over a year later, September 11, 2016, Gatt again made his return for Molde, coming on as a 67th minute substitute for Harmeet Singh. Gatt left Molde at the end of 2016, going on trial with 1. FC Nürnberg in January 2017, before signing with MLS team Minnesota United on February 15, 2017. On March 31, 2017Minnesota United FC traded Gatt, Mohammed Saeid, and an international roster spot to Colorado Rapids for Marc Burch and Sam Cronin. His option was declined at the end of the 2017 season. During the 2017 offseason, Gatt's wife Melissa was diagnosed with cancer. While acting as his wife's caregiver during chemotherapy, he played one game for NPSL club Detroit City FC. After her cancer went into remission, he re-joined Rheindorf Altach in June 2018. On July 16, 2018, Gatt officially signed with Rheindorf Altach. On 23 June 2020, Gatt signed for League of Ireland Premier Division club Dundalk.
International career
Gatt was called up to the United States national team on September 2, 2012, but he had to withdraw due a hamstring injury. He made his international debut on November 14, 2012 in a friendly match versus Russia. Gatt was originally named to the 23-man roster for the 2013 CONCACAF Gold Cup, but was later ruled out for the tournament after picking up a knee injury in a match on June 29 against Sarpsborg 08 FF.
Style of play
When Gatt was signed by Molde, Solskjær stated that he had signed an attacking player with a fast pace who can play on the right wing, left wing, and as a striker. Gatt has run a self-timed 100 meters in 11.00 seconds.
Personal life
Gatt’s wife, Melissa, was diagnosed with cancer in early 2018. Without a club, Gatt set up a ‘Go Fund Me’ page for her treatment which was contributed to by a number of his former teammates. As of June 2018, they had raised $78,000, and Melissa's cancer is in remission.
