This firm is very good. They gave me good advice and so far I’ll still have custody of my grandchildren and with his help I shall maintain that custody. Superior.- A Family Law Client, Philadelphia, PA
Petrelli Previtera worked with me on case and he was great. His staff and lawyers are so friendly and helpful. You can tell they cared by how quickly they returned my calls. Even if Mr. Petrelli was unavailable to assist me, his associate was there to answer my questions. I am very happy with their work and their rates are reasonable. If you need a family lawyer, these are the guys to go to.- A Pennsylvania Client, Delaware County, PA
