Dear Counselors:
Greetings!
Dear Counselors,
Mr and Mrs would be proper. Attorneys are typical written to as Mister.
The proper salutation for a letter addressed to a husband and wife who are both attorneys would be "Dear Mr. and Mrs. [Last Name]" or "Dear [First Name] and [First Name] [Last Name]." If you want to acknowledge their professional titles, you could use "Dear Attorneys [Last Name]." This conveys both respect for their professional status and addresses them as a couple.
Rabbi and Mrs.
