Based on all my experience in Massachusetts, I never witnesses an anti-Catholic bias in Orthodox parishes there. I gladly second all parishes recommended above. Been in all of those and highly enjoyed. Also, please let me mention my own parish - St. Andrew's Ukrainian Orthodox Church in Jamaica Plain, MA: http://www.ukrainianorthodox.org/
We have several converts from Roman Catholicism as well as several more from Eastern Rite Catholicism. And the parish is in southern suburbs.
