Spherical Yellow was formed by Margot Carter. Margot went from her home in Winchester, England to Tennessee Tech University after being awarded a full Tennis scholarship. She competed in the top 3 of the university team, succeeded in making the record books at number 5 on the all time season victories list, while also completing a Bachelors of Science in Environmental Biology. She then went on to compete on the Professional Tour, travelling around the world extensively and achieving a world doubles ranking high of 451. She returned to TTU as the assistant coach, and this time qualified with a Master of Science in Environmental Biology. However, Margot’s passion for Tennis couldn’t be stopped, and yet again, she found herself on a tennis court, this time completing various USPTA and PTR coaching qualifications, to elite professional and professional standard. This led to coaching opportunities all over the world, including a 1 month stint in the Caribbean successfully coaching two local girls to get scholarships to universities in the USA. There was just a little something missing in life though, and Margot just had to return to the world circuit for some quality competition! She re established herself with a world ranking in 2014, which peaked at 850, when a ruptured achilles tendon slowed things up. Margot recovered from this and she still competes on the Pro Tour, when she has time around all the coaching.
