Collin M.
Tennis & Pickleball Coach
Hi, I’m Collin! I’m from Pflugerville, Texas, and I’ve been playing tennis for 8 years and pickleball for 4 years. I first picked up a tennis racket at 11 and quickly fell in love with the sport, competing in tournaments by the time I was 14. Tennis has been a huge part of my life — it taught me discipline, strategy, and perseverance — and it also opened the door for me to discover pickleball. With my tennis background, I quickly excelled in pickleball and began competing in tournaments as well.
Over the years, I’ve developed a passion for coaching both sports. I’ve had the privilege of coaching players of all ages and skill levels, including coaching pickleball at Pickleland in Austin, Texas. My goal is to make every session productive and personalized, helping players improve their technique, build confidence, and develop a deeper love for the game.
Whether you’re looking to fine-tune your tennis strokes or level up your pickleball game, I’m here to help you reach your goals — and have fun doing it. See you on the courts!
Keiana
Coach
Hi, my name is Keiana! I’ve been playing tennis for over a decade, starting in middle school and continuing through high school and college. I’ve also been coaching for the past several years, working with both kids and adults, especially beginners at The University of Texas at Austin.
I really enjoy helping beginners build a strong foundation and feel comfortable on the court. I focus on things like positioning, technique, footwork, and developing good habits from the beginning. I believe that learning the basics the right way makes it much easier to keep improving as your game gets faster and more advanced.
My goal is to make tennis fun while helping each student build confidence and develop a solid game they can continue to grow.

Later he went off to play collegiate tennis at the University of Texas at Tyler. After college he went into tech sales for a few years but realized his passion wasn’t in computers but tennis and has shifted towards teaching and getting back on court.
In college he played against many different players and game styles and quickly realized everybody’s game differs slightly. Because of this he caters his lessons/drills to his players specific needs and goals for the future. Cameron’s focus is on helping people expand and
improve their current game, while also helping with match strategy .
He is a USPTA certified teaching pro and is excited to work with the next generation of players
to improve their game and develop a love for tennis.

Ali A.
Tennis Coach
​My name is Ali and I am currently a 3rd year architecture student at UT Austin! I’ve been playing tennis since I was 12, starting competitive tournaments around the age of 14. I was a USTA super champ and began my coaching career while high school giving private lessons. For the past two years, I have spent my summers running camps and drills with my former coach and continued with private lessons for players of all age and skill levels. I now play competitive doubles for the UT club team, currently ranked line 3 for the school. My style of coaching relates to each individual player, working with their unique strokes to make them the best player they can be. I value having a balance among all your shots rather than mastering one, and I think it helps create all around players that can face any situation. I hope to continue coaching throughout my college career and beyond as my love for this game has only gotten stronger as the years go on! My favorite player is the undisputed greatest tennis athlete of all time Novak Djokovic!

Zoë L.
Tennis Coach
Hi I’m Zoë, I’m from Henderson, Nevada where I started playing tennis at the age of 3! I loved it so much because I made so many new friends and was outside all of the time. I played competitively in the USTA until I was 16 and unfortunately injured my shoulder. Luckily being tall, I could switch gears and play volleyball! It took me to college as I got to play for Southwest Minnesota State University and earn my Bachelors Degree in Communications with an emphasis in Sociology. My love for tennis never wavered throughout the years and I kept at playing and learning the game. I’m so grateful I’m here now and it led me to coaching! See you on the courts!

Evan P.
Tennis Coach
Hi! My name is Evan, and I love the sport of tennis, which is why I enjoy coaching anyone and everyone who wants to play! I've played tennis for 16 years now, and growing up, I was able to become a "super champ" in old USTA terms. I played tennis at Concordia University Texas from August 2018 to May 2023, where I obtained my bachelor's degree in Kinesiology and master's degree in Sports Administration. During my time playing for Concordia, I was voted captain by my teammates for my last 3 years of college tennis. During those 5 years, we made it to the ASC conference championship 4 times, winning twice in Spring 2021 and Spring 2023! I'd say my coaching style focuses on a holistic approach, developing the physical, mental, and emotional aspects of the sport, to optimize development and performance, but I don't forget to bring the fun as that's the most important thing after all (winning is nice, too, though)!
