His last eleven years in the industry were as advertising head at Bayer Pharmaceutical. He retired from Bayer in November, 2000.

Vince was ordained a Deacon for the Diocese of Bridgeport in 1990 and since then has been assigned to St. Catherine pastoral staff. He reports, "St. Catherine has well-organized liturgies that facilitate our prayerful worship and place us all in Monsignor Detscher's debt. What a wonderful group of people we have. It is a gift to be able to serve and worship with them."

As a second career, from 2001-11 Vince was Director, Religious Education at Notre Dame Parish in Easton, CT. He is now retired from that position. He continues to be very involved in marriage-preparation work for the diocese and for the parish. Vince currently is the Property Manager for St. Catherine.

Among the joys of his diaconal service, Vince identifies the privilege of presiding at the weddings of his son and daughter, the baptizing of grandchildren and his many grandnieces and grandnephews in Pittsburgh. Among his hobbies, Vince is a computer "geek" and also thoroughly enjoys playing the Hammond Organ... popular standards of the 1920s-50s.
