In 2006, Esther rose to the very top of the junior ranks. She was named the AJGA Girl's Player of the Year. She won three events that year, including the Rolex Junior Girls Championship and the Ping Invitational, where she set a course record in the opening round. In all, Esther accumulated six AJGA wins in her junior career and was a four time Canon All American.

In late 2006, she signed a letter of intent to play for the University of Arizona in the 2007-2008 season. But she surprised everyone by turning pro right after the 2007 Nabisco in April. She played a few Futures Tour events and did pretty well, notching several top tens including a tie for second. But in the Fall, she failed to get through either LPGA Q-School sectional into the finals. Thus, she played the Futures Tour in 2008.

Amazingly, Esther continued to struggle with her game in 2008. She played only five events on the Futures Tour, finishing no better than 42nd. She returned to LPGA Q School in the Fall, but was not able to advance out of either sectional for the second year in a row. In interviews, she has confessed that she has no injuries; she has simply lost confidence in her game.

Esther played on the Futures Tour again in 2009, and finished only 120th on their money list, earning less than 4 thousand dollars. She had more success playing minor league tours such as the Cactus League.

In 2010, Esther finally had a good season on the Futures Tour. Although she didn't quite play well enough to earn an LPGA tour card, she came close. Esther competed in 16 events, with a top finish of tied for 2nd and 5 total top tens. This enabled her to finish 12th on the money list, just two spots shy of earning a card.

Her improved results did not help her much in 2011, however. She played in just 6 events during the year, with just one top ten, a tie for 5th. She earned less than $10,000. She tried once again to qualify for the LPGA at the end of the year, but failed. But there was light at the end of the tunnel: she entered Ladies European Tour qualifying and DID earn a card there, finishing 26th.

Esther finally had her breakout year in 2012. She played just 6 events on the Symetra Tour, but still won the Player of the Year and led the money list. She won two events and had two other runner-up finishes. It was the lowest number of events a player ever needed to win Player of the Year.

She also played on the European tour, where she earned four top 20s and one top five.

Alas, Esther's 2013 rookie year on the LPGA was not good. She did not make a single cut. She did not seem to play anywhere in 2014, but rejoined the Symetra Tour for 2015. That year, she only played two events, missed both cuts, and does not seem to be playing there in 2016. She may have retired.
