He competed in his first competition at the 2006 World Artistic Gymnastics Championships and finished in the 113th place in the all-around.
He finished third in the all-around at the 2009 Maccabiah Games.
He competed at the 2010 World Artistic Gymnastics Championships but didn't not place well. He finished in 69th place on the pommel horse, 75th place on the rings, 81st place in the all-out, 109th place on the parallel bars, 131st place on the horizontal bar, 189th place in the floor exercise and the 238th place on the vault.
In 2010 he started training at Pennsylvania State University and made a tremendous impact as a freshman, developing into one of the team's strongest and most consistent performers by the end of the season. He was named Big Ten Co-Freshman of the Year, Penn State's first winner of the conference award since 1997 and won the "Big Ten Freshman of the Week" honors twice. He recorded Penn State's highest scores of the season in the pommel horse (15.100), parallel bars (14.850), and all-around (84.800).
In 2011 he was in the "Academic All-Big Ten" and was named "National Gymnast of the Week" after capturing two first-place finishes (parallel bars and all-around) and a third place (high bar) versus Ohio State. He set career highs in five events (floor exercise, pommel horse, still rings, vault, and parallel bars) and the all-around. Once again he recorded Penn State's highest scores of the season in the pommel horse (15.100), parallel bars (15.400), and the all-around (87.150) and was nationally ranked No. 10 (parallel bars), No. 14 (high bar), and No. 16 (still rings) at the end of the season.
At the 2012 European Men's Artistic Gymnastics Championships he qualified for the all-around final in 11th place.
