I don’t know off-hand of any (other than Orthodox) in Dutchess, but there are several UGCC parishes in the vicinity:
Holy Trinity Ukrainian Catholic Church
211 Foordmore Rd
Kerhonkson, NY 12446-2914
St Andrew Ukrainian Church
141 Sarah Wells Trail
Campbell Hall, NY 10916
Ukrainian Catholic Church Parson
447 High Rd
Glen Spey, NY 12737-8608
plus there is are Maronite parishes in Torrington and Danbury CT, Watervliet (near Troy, NY), and a Melkite one also in Danbury.
There may well be others, but above few come to mind just now.
