THERAGUN was founded in 2008 by Dr. Jason Wersland after a severe motorcycle accident caused him to experience constant and debilitative pain. He was unable to find any handheld devices that provided deep muscle relief to treat his injuries. As a result, Dr. Jason spent 8 years developing 5 different prototypes, which led to THERAGUN's first product. The first announcement of their product, the G1 was introduced in 2016 and in 2017, the THERAGUN G2 became the leader of neuromuscular percussive therapy. Most recently in 2019, the G3PRO, G3, and Liv launched and is a game-changer, elevating wellness with even more effectiveness to help change the way people move.
