St. Nicholas-by-the-Sea began as an Episcopal mission in 1984. The founding priest was the Revd Diane Edson, who also started the now-thriving Wellspring Multi-Service Center
at the same time. St. Nicholas Mission enjoyed some success and later blended with the Pope Memorial Methodist Church, now known as St. Nicholas Methodist Church
. The Wellspring Center occupies a building named in honor of its founder Diane Edson, who died in 2000.
