M.B.
I am not sure exactly, I went to Catholic School in the Philadelphia Archdiocese for 12 years straight living in Bensalem.
My elementary school, St. Charles Borromeo in Bensalem helped some parents, they may have advice.
Also, check with the Chamber of Commerce and some of the political offices in the area. Just an opinion, politicians like to help, especially when any election is brewing in the air so they may know some pointers.
It's not easy but you will find one, did you look in Bensalem or Bucks County? Ryan and Conwell-Egan Catholic are great Catholic High schools that may help, good luck!!
