Master Marco Rosales began his martial arts journey in 1978 at age 13 in the Bronx, training under Sang Soo “Tiger” Kim, a renowned Korean martial artist. He spent three formative years at Tiger Kim’s dojo, where he trained alongside the Tiger Twins, Simon and James Kim. After his father’s passing in 1981, Master Marco took a brief break to explore music and art but returned to martial arts in 1997 following Tiger Kim’s death. He joined The Fighting Academy, training under Master Robert Tirado, Sensei Louis Ruiz, and Grand Master Sonny Mahai, all of whom influenced his style.
Seeking a more traditional Taekwondo experience, Master Marco trained at Tony’s Taekwondo and later explored Shotokan Karate with Sensei Frank and Kyoshi Derrick Williams. In 2000, he began studying under Grand Master Won Keun Bai and earned his black belt in Han Moo Kwan Taekwondo in 2002.
In 2013, Master Marco founded the Bon Yul HanMooKwan Taekwondo Dojang, blending Taekwondo and Karate to strengthen his students’ skills, especially in competition. His dedication earned him nominations for Instructor of the Year in three Hall of Fame organizations.
Master Marco encourages his students to embrace the true spirit of martial arts, believing that perseverance and discipline define a true martial artist. His philosophy is captured in his quote: “With Strong Body Comes Sound Mind, With Sound Mind Comes Pure Spirit.”
Now a 6th-degree black belt, Master Marco continues to teach, compete, and study martial arts history. He enjoys composing music, painting, and resides in Spanish Harlem with his wife Isabel. He also has 2 beautiful daughters Raquel and Lunna Bella.

Hello

Hello! I’m James Beatty, a Kukkiwon‑certified third‑degree black belt who began his Taekwondo journey with the MIT Sport Taekwondo Club during college. After graduation, I continued training at Yoo’s Martial Arts in Virginia, earning both my black belt and, later, my 3rd Dan under 9th‑Dan Grandmaster Jun Saeng Yoo. Now in New York for over 10 years, I’m preparing for my 4th Dan test under Master Shin at Broadway Taekwondo. I’m especially happy for the opportunity to train, teach, and grow alongside our students—particularly the kids—while sharing the discipline, respect, and perseverance that have made Taekwondo such a rewarding lifelong practice.

My name is Cecilia, and I have been studying Taekwondo for 10 years. I am a 3rd dan black belt and earned my instructor badge 4 years ago. I enjoy teaching TKD and sharing the martial arts philosophy with other students. I moved into New York City recently to study Classical Voice at Manhattan School of Music as a freshman undergraduate. I grew up in New Jersey, and I have a dog who is a Shih Tzu-Yorkie mix!

Hello, my name is Biko Yoon. I began practicing Taekwondo when I was in kindergarten, but I had to stop after earning my yellow belt because my previous school closed. I joined Broadway Taekwondo in 2023 and earned my 1st Dan in 2025.
I live in Harlem and attend Booker T. Washington Middle School, which is very close to Broadway Taekwondo. My elementary school was also nearby, so I have always felt comfortable in this neighborhood.
My mom is Korean, and practicing Taekwondo helps me stay connected to my culture. I can understand Korean fairly well, although I am not fluent. Training at Broadway Taekwondo has helped me feel more comfortable speaking Korean.
I have competed in three Taekwondo tournaments and plan to participate in more in the future. I especially enjoyed the Kukkiwon competition I took part in a few months ago. Outside of Taekwondo, I also enjoy volleyball and calisthenics.
My goal in Taekwondo is to practice more consistently at home and continue getting stronger. My long-term goal is to earn my 6th Dan and, hopefully, progress even further.

Hi. My name is Sureyya.
I live in NYC. I started at Broadway Taekwondo in 2023. I have a hairless guinea pig named Pepper and a dog named Scout.I am currently a red belt and am working to test into a poom belt.
Currently, my favorite part of Taekwondo is poomse, and I especially like numbers eight and five. I like poomse because it requires you to have the correct steps while still personalizing it.
As a junior assistant, I enjoy helping other students with their stances and I feel I am setting a good example.
Outside of Taekwondo, I like reading and school. My favorite author is “Rick Riordan”, my favorite book is “Song for a Whale”, and my favorite book series is “York”.

Hi! My name is Abigail, but you can call me Abby. I’m from the Upper West Side of New York City. I started Taekwondo in 2022, and I earned my poom belt in 2024. In 2025, I became a junior assistant, which has been so much fun!
My favorite part of Taekwondo is doing poomsae. Right now, my favorite one is Taeguk 8 Jang. I’ve competed in the New York International Championships in Queens twice, and I won gold medals in poomsae! I want to keep joining tournaments and work hard to become a great athlete.
Right now, I’m training for my black belt promotion. My big dream in Taekwondo is to become a Master one day.
As a junior assistant, I really enjoy helping my friends—holding targets and boards, and helping them with their poomsae.
Outside of Taekwondo, I love outdoor activities like running and playing badminton. I also enjoy drawing and making origami!

Hi, my name is Ruben Wolf. I am from New York City. I started Taekwondo four
years ago in 2022. I am 12 years old and I have a sister named Nomi, and a cat
named Bruce. I am a black belt in Taekwondo and hope to get my second Dan.
I go to Booker T. Washington middle school between 107th and 108th on
Columbus. My favorite sports are Pickleball, ping-pong, tennis, and Taekwondo.
I have fun in school, but I always feel the most comfortable in Broadway
Taekwondo and at home. I love being a role model for other kids who don’t feel
as comfortable with Taekwondo, and I love to help out with the younger classes.
My goal one day is to become a master of Taekwondo, and outside of
Taekwondo, my dream is to be an architect, and maybe meet the Stranger
Things cast. I love to travel, and someday I would love to go to Korea. And when
I go, I’ll know a little bit of Korean thanks to master shin and Broadway Taekwondo

Hi! My name is Ella. I started Taekwondo at Broadway Taekwondo in 2022. In 2025, I earned my poom belt, and now I’m training hard for my next goal — the black belt!
In 2025, I also joined the Leadership Team. I help the instructors and support other students, especially the younger ones. I love helping them with their targets and memorizing hard poomsae. It makes me feel proud and happy. One day, I want to become an awesome instructor too!
My favorite part of Taekwondo is practicing poomsae. I like learning all the moves and training again and again to make them look even cooler. Right now, I’m focusing on Taegeuk 8, and I think it’s the most exciting one so far!
Outside of Taekwondo, I love outdoor activities like running, swimming, and gymnastics. I also really enjoy collecting stickers — especially cute ones! It’s fun to trade and share them with my friends. Oh, and one more thing… I LOVE ramen!
