What languages do you speak?
I speak English and Spanish.
At what age did you start playing tennis?
I started playing tennis when I was seven and a half years old.
Are there other tennis players in your family?
My dad plays tennis, and other people in my family also play.
In which tennis clubs do you train?
I train at Parklangley Tennis Club and Sundridge Park Tennis Club.
Who is your coach?
My current coach is Brett Spencer, an LTA Level 5 Master Performance Coach, from Parklangley Tennis Club.
What is your greatest strength as a player, and what do you need to improve?
My strength is my determination to succeed. I am also hard-working and very competitive. I am currently working hard to improve my game generally, while continuing to improve my forehand, backhand, serve techniques, and footwork.
What is your age category and national ranking?
I am in the 2014 age group, and my current ranking is No. 27 in the UK.
What have been your greatest successes so far?
I am the Kent County Champion in 2026 in the 14U and 16U age groups. I have also reached the semifinals of a Tennis Europe International 12U tournament in both singles and doubles, and I have played many Lexus British Nationals Grade 1 and 2 championships.
In which countries have you played tournaments?
I have mainly played tournaments in the United Kingdom.
What equipment brands do you currently use, and are you sponsored by any of them?
I use Babolat Pure Drive racquets, Wilson Revolve Spin strings, Babolat Propulse shoes, and different clothing brands. I am not sponsored at the moment.
What is your next goal?
My goal is to improve my tennis every day, earn a spot in high-level college tennis, and test myself on the professional tour to eventually become a professional tennis player.
What is your tennis dream?
My ultimate tennis dream is to compete at the highest level of the game, play in the main draw of a Grand Slam, and consistently contend for titles. But the dream is not just about lifting a trophy. It is also about building the day-to-day grit, mental discipline, and consistency it takes to get there.
Who are your favorite players and why?
My favorite players are Elena Rybakina and Aryna Sabalenka. I like Rybakina because she combines a lethal, highly accurate serve with explosive, flat groundstrokes and ice-cold mental composure under pressure. I admire Sabalenka for her devastating power, aggressive baseline control, and remarkable athleticism.
What do you enjoy doing outside of tennis?
Outside of tennis, I like music, dancing, and spending time with my friends and family.
Who would you like to dedicate this interview to?
I would like to dedicate this interview to my family and to all the people who support me in my tennis journey.
