At New York Ninja Academy, children and adults of all skill levels learn how to analyze, approach, and conquer ninja warrior obstacles. Our challenging and unique obstacles reflect those seen on NBC’s American Ninja Warrior.
Have fun and push yourself to new limits! Kids classes are geared towards learning the basics, and progressions, adult classes are designed for all levels, and advanced one-on-one classes prepare athletes for competition. Many of our staff and students have been Ninja Warrior competitors, and even some of our young students have competed on American Ninja Warrior Junior.
We are a diverse group of ninjas with various athletic backgrounds


Madelyn Scarpulla is a long-time music industry professional having held senior marketing and creative positions at several major and independent record labels, and a major-market radio station. Madelyn made the bold decision to open her first ninja warrior training facility in 2019. “Opening New York City Ninja Academy, then Brooklyn Ninja Academy, then Los Angeles Ninja Academy and now Ventura Ninja Academy allowed me to combine my entrepreneurial skills and business savvy with my life-long passion for athletics. My terrific team and I have created a thriving close-knit community of ninja families and athletes in all four locations on both coasts. I am incredibly proud of what we as a team have accomplished."

Originally from Ithaca, NY, Sean O'Shea has been living in New York City for over a decade. When he’s not coaching, or competing in the World Ninja League, he’s writing, directing, and acting on stage and behind and in front of the camera, and performing his original singer/songwriter music. A regular competitor in the World Ninja League, and a certified personal trainer, Sean is excited that his future is Ninja Warrior, and he has the opportunity to inspire those he teaches.

Coach Cleon has been training parkour since he was 14 years old. As a former child himself, he loves the idea of instilling confidence in a younger generation. He enjoys weightlifting, video games, traveling, and skateboarding. Cleon’s super power is that he remembers the faces and names of all the kids he coaches. While they are often mistaken for one another, Coaches Cleon and Ashante (Brooklyn) are not the same person, nor are they related.

Law Williams has an extensive parkour and gymnastics background, and has been coaching ninja warrior for over 7 years. Coach Law loves to work with his students to achieve their specific goals. His positive attitude and great energy is contagious with the kids that he coaches, and his class environment is always full of encouragement and support. Law continues to improve as a coach and a ninja himself, as he now competes in the World Ninja League. He’s inspired by the kids, his fellow coaches, and the desire to compete in the WNL.

L to R: Coach Wray, Coach Graydon, Coach Malone – our long time ninja students and competitive team members have become coaches themselves. Wray joined us on the first day we opened our doors as one of our first students. Graydon has been training for 5 years and is a member of our competitive team. Malone, our youngest coach, achieved #1 Preteen Female spot and Strongest Ninja in the World Ninja League Season IX, and #3 Teen Female World Champion Season X, and now competes at the Elite level in the World Ninja League, and NSC.

Coach Sebastian was a Division I Track & Field Athlete at Stony Brook University and has earned MVP for his football, wrestling, and track teams. He was a javelin thrower and a sprinter.

My child is growing in confidence and is working on his strength and stamina in a fun, motivating and social atmosphere!
Wow! By far the best birthday experience my 3 sons ever had. Our instructors were amazing teaching 10 energetic boys! We will definitely be signing up for classes. Great facility too!
We celebrated my daughter’s 10th birthday at NY Ninja Academy. My 12 year old son and his friend joined in the party. Everyone had a wonderful time. The staff was great with the kids. On the way home the 6 kids I had in the car could not stop talking about the instructors and how much fun they had. Highly recommend.
We love this place. The coaches are fantastic. My kid feels challenged and has learned new skills he can use both inside and out of the gym.
As if by magic, the owner has found a talented/kind group of coaches and staff. Their management of the kiddos during classes is an astonishing mix of teaching through encouragement, support and persistence. They never let a kid get discouraged – in fact, making sure every kid walks out of class with their head held high seems to be the priority.
Fun and engaging for kids and adults! Warped walls, balance obstacles, and a million other challenging stations to conquer! Like nothing else in the city!
This was a blast! My kids took part in an introductory Drop In class and loved it! Instructors were attentive, knowledgeable, and patient. Stressing safety and inclusion, my kids came away from this feeling empowered, and begging to come back.
The customer service is INCREDIBLE! Both via email with reservations and reschedulings, and the coaches are so nice! Great place to have a birthday party, even for adults!
I love this place! I live close by so it kind of feels like a second home to me. Thank you guys for the good vibes and awesome obstacle courses. I highly recommend training here.
My son competes in the World Ninja League and NYC Ninja Academy is one of THE BEST gyms on the circuit! The gym, equipment, and amazing staff make this a favorite location to visit and definitely a highlight of our season!! If you haven’t been there you should check it out, you won’t be disappointed.
