She started riding very early on, encouraged by her mother who inspired her to take riding lessons at the age of six. At the age of 13 she got her first pony, with whom she competed in the European Pony Championship.
A little later, Jonna represents her nation, Sweden, in the 2008 European Championships in Prague as a Junior rider. Determined to improve more and more, in 2013 she joined the Stephex Stables family, where she started to grow technically and consolidated herself as an international female rider.
In 2015 she began to compete in the 1.50 competitions and dreams of one day competing in the most coveted circuit: the Olympics. She loves to compete, but she also loves to be behind the scenes training the younger horses and seeing them improve.
