Margot, formerly world ranked 451 is the Founder and CEO of Spherical Yellow Inc, a company dedicated to all aspects of growing Tennis. She is a USPTA Elite Professional and PTR Professional Coach and Clinician. Margot has presented at multiple USPTA workshops, the WTCA Conference in NYC 2018, the WTCA ITA collaboration in Naples, FL 2018 and most recently the Jacksonville area USPTA RED day. 

This journey in Tennis began when at the age of 18 Margot left her home in Winchester, England, to attend Tennessee Tech University afterbeing 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. It is after this that 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. It was at this point that Margot formed Spherical Yellow and launched herself into the world of Coaching and Tennis business full time. Aside from coaching and speaking at conferences Margot also trains coaches as a PTR clinician, and is the voice of the WTCA podcast, “A Tennis Connection”, also on instagram here.
