The founder of Diamond Tennis Academy has been coaching since 2000.

Sena holds a UKCC Level 5 award (Master Club Coach qualification), an Accountancy and Management degree from Cardiff University and a Professional Practise in Tennis Coaching Management degree from the University of Northumbria.

Coaching Assistant: Will Iles

Will holds a LTA Level 1 award and is fully accredited. As a child I was always pushed into football and rugby throughout school. However, while I enjoyed playing both I never found a love for either. It was much later in school where I attended an open day at a local tennis club. While it didn’t come naturally to me, I kept attending and improving and found a love for the sport. This is the main reason I coach, to bring tennis to more children and give them the chance to fall in love with tennis as well.

Working at Diamond Tennis Academy is amazing, I get to bring tennis to children and adults from diverse backgrounds and help them improve their skills. On top of this, the whole team are friendly which makes me want to come to work even more!

Coaching Assistant: Abbie Lake

Abbie holds a level 1 coaching qualification. I have been playing tennis since the age of 5, competing in many tournaments over time. I have been volunteering in tennis since the age of 12 and at the age of 15 was a finalist of the Tennis Wales young volunteer of the year award. I have always been passionate about tennis and enjoy sharing my love for the sport with others.

Outside of tennis I am entering my second year at sixth form, I spend my spare time singing and writing my own songs for social events and volunteering as a girl guide leader.
