  • Mario Guerrero

    Youth Fitness Specialist

    My name is Mario Guerrero, and I’m originally from Guayaquil, Ecuador. I have been living in New York for the past 9 years.

    I have earned my bachelors of science in kinesiology and movement science, and I have also become a Youth Fitness Specialist Level 1.

    I started working with children as a teenager, and have been part of summer camps in New York that worked with children from 10 to 14 years of age. I have also done volunteer work in little league teams from churches in Brooklyn and Queens.

    My latest non-profit work was in Harlem in an after school program that worked with middle school kids (6-7- and 8th grade)

    I have also done personal training for adults at different companies since I was 19, and I'm still heavily involved with this type of work.

    My work with Energetic Juniors has helped me evolve as a youth trainer and it has provided me with a vast amount of experience that will help me advance. I'm looking forward to continuing my education and growth as a professional with Energetic Juniors.

  • Colleen K.

  • John Snow


    John Snow is a boxing trainer/personal development coach with over 20 years experience. Born and raised in Brooklyn, John's life changed when he gathered the courage to climb the stairs of the famed Gramercy Gym near Union Square. It was there that he began the never-ending journey called boxing. Through the various stages and challenges of life, he realized that the one thing that helped frame his success was what he learned about himself while boxing.

    Unfortunately, most people boxing today miss the most important component of the sport—that is ,the mental training required to win and the relationship between fighter and trainer. It is this training that is so valuable to children and teens. Regardless of their athletic ability, boxing, when taught properly, will develop a strong sense of self confidence, discipline, and self reliance that children will be able to utilize both in school and everyday life.

    John is a graduate of Fordham University as well as a CPT with the National Academy of Sports Medicine. He is most proud of his role as a father to his 13 year-old son.
