# Hee-kyung Seo

Hee-kyung Seo (Korean: 서희경, born July 8, 1986), also known as Seo Hee-kyung, is a former South Korean female professional golfer playing on the LPGA Tour and on LPGA of Korea Tour. She won the LPGA Tour Rookie of the Year award in 2011.
After winning three LPGA of Korea Tour major championships in 2009, Seo notched her first LPGA Tour triumph at the 2010 Kia Classic where she finished six shots ahead of Inbee Park.
Seo had a close call in the 2011 U.S. Women's Open when she led by two shots with two holes to play, but she missed a 4 footer for par on the 71st hole, while So Yeon Ryu birdied the 72nd hole, resulting in a playoff, which Ryu went on to win.
Seo also came close at the 2012 Kraft Nabisco Championship, where she led by three strokes at one point, but bogeys on the last four holes would result in her finishing two strokes back of winner Sun Young Yoo.
On November 30, 2013, she married Junghoon Philip Kook (born 1979), an executive officer at DWS Asset Management based in Seoul, and gave a birth to their first son, Dohyun Philip Kook on August 15, 2014, on the Independence Day of Korea. Since then, they had two more sons, Dohoon Francis (born 2016) and Doheon Michael (born 2018). Seo officially retired from professional golf in November 2015 to spend more time with her family.
