Philly Area Groups

My husband and I recently relocated to the Philly area (just outside the city). We are currently waiting to adopt a baby domestically. We are working with a private law firm/agency and yes....the waiting has begun! I am trying to find a group for adoptive or prospective adoptive parents in our area. I think it would make our waiting process a bit more normal, less anxious if we knew other families in our same situation. I am a social work by training myself, but know little about what is in the area since we just got here. Any thoughts? Thanks! Vanessa
