The new CEO Maria was already the Chairman of BMOD. The CEO is still President. They have increased Maria's role with the company.
You are confused in thinking John Cousins has left the company this is not correct. They just rewarded Maria's hard work with an increased role.
Maria Zannes, chairman of the board of directors, has been appointed chief executive officer, effective immediately. John Cousins will continue to serve as company president and chief financial officer.
