Deacon Mike Van Dyke was born in Grand Rapids in the early 1960s and baptized on the day before Christmas. He is the oldest of three. After moving numerous times through many mid-west states, his family returned to Grand Rapids in time for him to finish high school and attend Michigan State. While he was finishing up his degree, his family moved to Atlanta, where he met his wife, Juanita. This summer they celebrate their 36th anniversary!
In 2000, he convinced Juanita to move to Michigan, a decision they do not regret. Deacon Mike’s calling to the diaconate began shortly thereafter. During his discernment, Juanita joined the Church at the Easter Vigil in 2008. With Juanita’s blessing, Deacon Mike applied for and was accepted into formation in 2013. He was ordained to the permanent diaconate on October 5, 2019 and assigned to the Cathedral of the Most Blessed Sacrament.
