In 2004, Marshall climbed Mount Everest and Mount Elbrus (two of the Seven Summits) as fundraisers for the Sisters. This followed Lisa becoming (in 2003) the first woman to complete the Grand Slam of Ultra Running (four 100-mile races) and Badwater in the same year.

Their combined efforts helped the Sisters to raise more than $294,000 for Child Headed Households in Africa.
