Megan Moulton-Levy’s first introduction to tennis was at age 3 when she played with her family every Sunday. Although a doubles specialist, Moulton-Levy reached a career-high singles ranking of No. 237 in 2009.

Moulton-Levy’s professional career began in 2001 when she played in her first ITF doubles tournament with Shadisha Robinson in Aventura, Florida. In 2004, Moulton-Levy won her first ITF Circuit doubles title with partner Alanna Broderick at Alcobaca, Portugal after defeating Krizia Borgarello and Silvia Disderi in the finals 7-5 and 6-1.

Graduating in 2007, Moulton-Levy attended the College of William and Mary in Williamsburg, Virginia, where she was a 6-time All-American player. She also earned Colonial Athletic Association Player of the Year on the tennis team for each of her four years, only the second time an athlete in any sport won the award each year of their collegiate career. With teammate Katarina Zoricic, Moulton-Levy won the ITA National Indoor Doubles Championship in her junior year. The duo achieved the No. 1 national rank among doubles teams. She also received the national ITA/Arthur Ashe Junior Award for Leadership and Sportsmanship and set the record at William and Mary for most combined singles and doubles match victories. 

After college, Moulton-Levy played on the WTA Tour and qualified five times in 2009. The following year, she won five doubles titles with Lindsay Lee-Waters on the ITF Circuit. In 2012, she won one doubles title on the ITF Circuit at Osprey, Florida, with returning partner Lindsay Lee-Waters. In the finals, they defeated Alexandra Panova and Lesia Tsurenko. Moulton-Levy reached her career-high doubles ranking at No. 50 in 2013. In 2014, she won the WTA doubles title at Monterrey, Mexico, with Darija Jurak.

Moulton-Levy last played professionally in 2017. She currently acts as the general manager of player development at the Junior Tennis Champions Center. There she oversees all aspects of the high-performance program, which has helped to develop athletes including Hailey Baptiste, Denis Kudla, Robin Montgomery, and Frances Tiafoe.

She also currently acts as a Pro Ambassador for Athlete Ally. Moulton-Levy says of her decision to work with the organization, "As an openly gay athlete I am in a unique position to speak out about LGBT issues. After getting married in December to my partner of 7 years, I have become more passionate and dedicated to the LGBT community’s fight for equal rights. My hope is that by stepping forward as an Ambassador I will give a voice to those who may not have a voice at all. If I can do that for just one person then joining forces with Athlete Ally was worth it." The organization is working to end homophobia and transphobia in sports and believes in equal access, opportunity and experience in sports, regardless of sexual orientation, gender identity, or gender expression.

She is also serving on the USTA Board of Directors. She is one of three former WTA pros on the Board as an Elite Athlete Representative. They, alongside Marisa Grimes, the USTA’s first chief diversity and inclusion officer, are focused on fostering a more inclusive and equitable environment in tennis. Discussing her position, she explains, “I occupy a unique space on the Board because I was an elite athlete and I played tennis at the highest level. But as I mentioned earlier, my mindset is all about the joy and the love of the sport.”
