The longtime Health Commissioner for Nassau County will be stepping down.

Dr. Larry Eisenstein announced his resignation Sunday night as he seeks a new role in the private sector.

Eisenstein has been the commissioner since 2009.

Nassau County Executive Bruce Blakeman said, "Starting today, I will launch a nationwide search to find the best of the best who can build on Dr. Eisenstein's achievements and ensure the continued health and safety of our residents."

Eisenstein's resignation will take effect at the end of July.
