In 2001, St. Mary Parish in Peshtigo was linked to SS. Joseph and Edward Parish in Walsh, although both are still separate parishes. In 2002, Fr. Jim Massert hired Sr. Helen Plum, SSND, to assist him with the two parishes. Sr. Helen became the pastoral leader in 2005 and led the parish until 2016.
St. Mary Parish formally celebrated its 150-Year Anniversary at the 10am Mass with Bishop David Ricken on October 25, 2015.
In August of 2016 Fr. Jesus (Jess) Bascuna Berdol, from the Philippines, became the new administrator for the two parishes. He continues to lead the two parishes to this day.
