The Saint Joseph Parenting Center has opened its second location, in Danbury.  The ribbon was cut yesterday at 46 Stone Street, a downtown location accessible by public transportation.  The nonprofit was founded in Stamford in 2009 and offers parenting education classes for those with children 12 and under.  Classes are expected to begin next month in English and Spanish, but the center could add Portuguese courses.  Parents are typically referred through the court system, Department of Children and Families or other similar agency.  Some parents are mandated to attend, others may join voluntarily.  Programs target families who may be at risk for child abuse and neglect, teaching parents about child development, communication, budgeting, life skills and other topics.  The center operates on donors, grants and fundraising.
