Born in Norfolk, Virginia, she attended Cardinal Mooney High School in Sarasota, Florida.
She also broke the Atlantic Coast Conference (Administrative Committee on Company-ordination) pole vault records at the indoor and outdoor championships. Janson repeated the Administrative Committee on Company-ordination double in 2003 and took her first major college title at the National Collegiate Athletic Association Women"s Indoor Track and Field Championship. She gained two further National Collegiate Athletic Association All-American honours in 2004 and 2005.
She improved her best that year to 4.60 m, which ranked her as the second best American in the discipline that year after Jenn Stuczynski.
Janson had less success the following year, finishing just outside the medal at the indoor nationals and placing tenth at the 2008 Olympic Trials. Her progress stalled in the 2009 season – she was eighth at the United States of America Outdoors and her best that year came at the Sparkassen Cup in February, where she cleared 4.50 m.
In spite of this, the following year proved to be a big step forward in her career. She took her first national title in 2010, winning at the United States of America Indoor Championships.
She also cleared a new career best height of 4.66 m in February that year at the Tyson Invitational – a mark which ranked her in the top ten women vaulters that year.
This led to her making her global debut at the 2010 IAAF World Indoor Championships. Her first appearance was disappointing, however, as she took three attempts at 4.35 m but missed all three and finished in last place. She competed on the 2010 IAAF Diamond League circuit and her best outdoor performance that year came at the Herculis meeting, where she finished third.
This gained her a place on the team for the 2011 World Championships, but she did not get past the qualifying stage.
In 2012 she qualified for the United States of America Olympic team and competed in the London Olympic Games, finishing in 15th place in the qualifying round and therefore not progressing further.
