Hawaii Health Connector executive director Coral Andrews is resigning from the state's health insurance exchange effective December 6.   Andrews said she was not forced to resign. "This is my choice," she said, adding that she recommended to the exchange's board that it was time for a leadership transition. Andrews says Hawaii Health Connector has been her baby requiring constant nurturing and attention. The connector has reached a point where "I now need to let go and let someone else take charge." The Connector's board of directors named Tom Matsuda, the state's Affordable Care Act implementation manager, interim executive director effective December 9 and has launched a search for Andrews' replacement. She was paid $175,000 a year as executive director.
