PHOENIX (AP) -- The Arizona State Medical Board is looking for a new executive director.
Lloyd Vest resigned after less than six months on the job for undisclosed reasons.
Board members announced after a 2 1/2-hour executive session Wednesday night that Vest's resignation was effective immediately.
They say none of the events that led to Vest's decision involved issues related to public health and safety concerns.
The 60-year-old Vest has been the board's executive director since March.
The board regulates and licenses physicians in Arizona and is the state's top medical licensing entity.
Lisa Wynn was fired last October for unlawfully expediting physician licensing.
The licensing procedures then were overhauled, slowing the process and leading to a backlog of more than 700 pending physician licenses as of March.
