    • st clare parish-striving to be green!
      Since 2007 when our new church was built, St. Clare has been making consistent efforts to be ecologically aware and sustainable. We take our Franciscan spirituality seriously, and also recognize how careful, enlightened stewardship of creation is part of our responsibility as disciples.  We have a parish Earth Concerns Committee which attempts to keep our environment before the eyes of our parishioners, offering educational activities and maintaining a weekly bulletin box.
