Grand Slam-winner and former Wales centre Sonny Parker will attempt to lead a London Welsh revival after taking on a Director of Rugby role.
Welsh, who will play in Herts and Middlesex League 1 next season, have drawn up a five-year plan in their bid to return to the National League structure.
"I want to help get the club back to where we want it to be, and I believe the five-year plan is an achievable one," Parker said.
"The first year is going to be the real indicator, but the ambition is definitely there to make the plan a realisation."
Welsh's amateur side will represent the club next season in level nine.
