As of August 15, 2019, Fr. Edward Stafford was assigned the additional pastoral duties for St. Ambrose in Garrettsville and St. Michael in Windham. St. Michael, first designated as an oratory, was merged with St. Ambrose by Bishop Bonnar effective on December 12, 2021.

Two Catholic parishes in Portage County have formally merged, after operating as part of a "collaborative unit" for two years.
St. Michael in Windham has merged with St. Ambrose in Garrettsville. Leaders from the Diocese of Youngstown said the recent decree from Bishop David Bonnar formalizes a plan put in place in 2019. 

Previously, the Diocese said, St. Michael switched to oratory status in 2019, meaning that it has been open only for special Masses and prayer services, including weddings and funerals. The parish, leaders said, has been part of a collaborative unit with St. Ambrose in Garrettsville and St. Joseph in Mantua since the 2019 Pastoral Plan, with Masses at St. Ambrose and St. Joseph. The Rev. Edward Stafford oversees all three parishes.
“Both St. Joseph and St. Ambrose parishioners have been welcoming, and our region continues to be blessed by vibrant ministry," Stafford said. "Beyond parish boundaries, parishioners in northern Portage County have a long history of working and praying together regionally as neighbors.” 
Since regular Masses ceased at St. Michael, parish and diocese leaders said, the parish has been available for weddings and funerals. However, requests were fewer than anticipated, with only one wedding and two funerals since 2019. 
Parish and diocesan leaders say they will continue to study the resources available to support St. Ambrose, and make a final decision about the future of St. Michael Church in Windham soon. No immediate plans for the building in Windham were announced.
The announcement about the Portage County parishes came amid other announcements in the Diocese, including that St. Stanislaus Parish in Youngstown had been "canonically suppressed." The Youngstown parish held its final service in June 2020. 
Last month, Bonnar, addressing local Catholics at The Overlook in Twin Lakes, urged them to be adaptable and embrace change. He addressed the closing of two parishes in Campbell in Mahoning County, which had merged years ago but continued to alternate services between the old parish buildings. 
Portage County is one of six counties in the Diocese of Youngstown. It has 10 parishes, but only three — Immaculate Conception in Ravenna, Our Lady of Perpetual Help in Aurora and St. Joan of Arc — have a priest who is not also serving elsewhere. Church law, Bonnar told Catholics recently, forbids priests from saying more than three Masses in a single day.
