Alexandra Armas has decided to step down as executive director of the Ladies European Tour at the end of this year.
After gaining a bachelor degree in economics from Wake Forest University in North Carolina and playing professionally herself, Armas took charge of the circuit in 2005.
The Spaniard will work closely with the Tour Board on the selection process for her successor.
"I truly believe in the strength of women's golf and feel privileged to have had the opportunity to help with the development of women's golf and the LET," she said.
"With the LET in a better business position than ever and with a strong team and structure in place, it is now the time for me to consider new challenges and projects."
Karen Lunn, chairman of the board of directors, said: "Alex has been an asset to the Ladies European Tour, driving the company forward and impacting the growth of women's golf across the globe.
"Thanks to her commitment, loyalty, business understanding and insight to the players' requirements, the Tour has been rewarded with positive results and is financially well placed for continued success.
"During her tenure the LET has continued to expand with 15 tournaments in 2004 to 25 in 2012, with a roll-out in new territories such as Dubai, India, New Zealand, Turkey and China."
