The former American Samoa hospital CEO, says his sacking was due to irreconciliable differences with the board.
Last week, Joseph Davis-Fleming was served with a termination letter after he was found to be unfit to continue.
He was appointed to the role in April last year.
The board gave Mr Davis-Fleming a chance to resign first.
Mr Davis-Fleming says his work and efforts to turn the LBJ Hospital around for the better started to take a downward turn when the former LBJ board chairperson Tofoitaufa Sandra King Young left the board.
