Six Flags Entertainment Corp. has named a new top lawyer as the amusement park operator's longtime general counsel steps off the roller-coaster ride of leading a legal department and heads into retirement. 

Laura Doerre will take over for Lance Balk on March 9, according to a SEC filing on Tuesday. Doerre, who currently serves as the chief lawyer for door and window maker JELD-WEN Inc., assumes control of Six Flags' legal department as the Texas-based company grapples with a downturn in business. 

Six Flags reported on Feb. 20 that its revenue for the fourth quarter of 2019 was $261 million, a decrease of $9 million, or 3%, when compared to the same quarter in 2018. The company, which has 26 parks across the U.S, Mexico and Canada, cited a 3% drop in attendance and a 1% decrease in sponsorship, international agreements and accommodations revenue as the primary reasons for the loss.
