Blair has been a commissioner with the Postal Regulatory Commission since 2006, and served as its first Chairman. Blair's current term expires in October 2012, but he will leave early to take over full-time responsibilities at NAPA in early July, according to a spokesman.

Before joining the regulatory commission's precursor, the Postal Rate Commission, Blair served as deputy director and as acting director of the Office of Personnel Management.

Blair became a NAPA fellow in 2008, and is replacing outgoing president and CEO Kristine Marcy.
