This firm owns the domain "special-ed-law.com", and probably a few variants thereof. They specialize in special-ed law in New Jersey because a senior partner's child was disabled. I suspect that's not an atypical story.
The links they provide on this page are (largely) not specific to New Jersey.
It's probably not a great idea to start IEP discussions with a lawyer at one's side. On the other hand, periodic consultations may be valuable. Just remember to use your own judgment!
