The chief legal officer and chief financial officer of Nobilis Health Corp. have resigned as the  Houston-based health care company prepares to be removed from the New York Stock Exchange for failing to file earnings reports. 

Nobilis notified the SEC on Monday that CLO Marissa Arreola and CFO Brandon Moreno had resigned days earlier Sept. 6. The filing did not explain why Arreola and Moreno headed for the exit and attempts to reach company representatives were unsuccessful. The Houston Business Journal first reported on the resignations.
