Michael J. Pasquale, Esq.
146 Rea Avenue
Hawthorne, NJ 07506
The address was copied right from the OAE website. I don't know why they have a phone number listed or what would happen if you tried to call and complain in person. OAE does have a hotline number but all it does is get your address so they can send you the grievance form. I was unable to find anywhere to place a complaint online.
