The most certain way to contact Adam Guettel would probably be to ring up the Dramatists Guild and ask who his agent is and the agent's phone number. Then ring up the agent and ask for a mailing address for the agency, and send a letter to Adam in care of his agent. I would not recommend asking either the DG or Adam's agent directly for personal contact information.
On the other hand, why don't you simply check the white pages of the Manhattan telephone directory, or use one of the many free online services which essentially look up numbers in published telephone directories? His name is hardly a household word, and he's probably listed in the regular phone book just like ordinary mortals.
