Mario G.


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.

NASM-CPT, Youth Exercise Specialist and Adaptive Special Needs Fitness Trainer (Strong Education)

While attending school for business at Fordham University and working in advertising for a sports television network, exercise was always Colleen’s outlet. Colleen found that setting goals and achieving them inside the gym translated to her life outside of it. After three years of working in a corporate environment, Colleen decided to leave her job to pursue a career within the fitness industry. Colleen spent three years working in management for a small boutique fitness studio, and while there, she obtained her personal training certification through NASM. She thoroughly enjoys helping her clients set and accomplish their fitness goals.

Colleen has always had a passion for working with children. As a teenager, she began working as a camp counselor and continued to work with children by babysitting for multiple families in Manhattan. As a trainer at Energetic Juniors, Colleen enjoys combining two of her passions: fitness, and children! She believes that fitness is not only a great tool in creating physical changes, but also (and more importantly) it is a tool towards improved confidence, self-esteem, and outlook.

Colleen has earned her Youth Exercise Specialist certification through NASM and her Adaptive Special Needs Fitness Trainer certification through Strong Education. She can’t wait to help her youth clients reap the positive benefits of fitness!

John V.


I believe the best time to start practicing fitness and health was yesterday. The second best time is today.

No matter what age – young or old – I enjoy helping enrich and change lives through training. Since being diagnosed with Type 1 Diabetes as a teen, I decided to take action about how I wanted the rest of my life to be – long, healthy and joyful. I took up training and quickly realized my calling was not just to train myself, but others as well. From being a summer camp counselor in my high school years to formally training teens now, I have always enjoyed working with kids and young adults. It is never too early to learn good movement “habits,” and stay ahead of the curve with sports performance and strength.

I am currently certified by NASM and am pursuing a Doctorate of Physical Therapy. I emphasize correct, efficient movement that transfers over to sports, daily life, and addresses stability and strength. I am well versed in many modalities and enjoy being creative with whatever equipment is available. Most of all, I enjoy making workouts fun, challenging and engaging!

Chao L.

As someone who has struggled with poor diet and physical performance, Chao hopes to simplify the components to maintaining a healthy lifestyle for adolescents and adults. She has had extensive experience training sedentary youths all the way to athletes in sports teams.

Chao holds a Bachelor’s degree in Exercise Science and is certified by NASM as a performance enhancement specialist.

“People are not fragile. Fitness has been life changing for me, and I hope more people can see the value in being the strongest versions of themselves, instead of having to fixate over seeing the smallest number on the scale or having to worry about what they’re eating on vacation.”

“The foundation of every state is the education of its youth.”

“We are what we repeatedly do; excellence, then, is not an act but a habit.”
-Will Durant

“No man has the right to be an amateur in the matter of physical training. It is a shame for a man to grow old without seeing the beauty and strength of which his body is capable.”

These three quotes exemplify my philosophy on training. Train as early as possible, consistency is more important than intensity, training is the foundation of unlocking your body’s full potential. With these in mind you will be capable of taking on any challenge life throws your way.

I currently hold a Bachelor of Science degree in Exercise Science, a Bachelor’s of Arts degree in Psychology and a minor in Sociology. I am a certified phlebotomist, certified medical assistant, and certified personal trainer through the National Academy of Sports Medicine. I hold black belts in multiple martial arts and have been training since 1994. I have worked as a physical therapy tech for three years where I have worked with children. I have also worked with children in my martial arts classes and as a medical assistant.

ACE Certified personal trainer, precision nutrition level 1, mobility and corrective exercise specialist

I was always active as a kid, doing everything from playing basketball every day after school to going camping over the summers with my Boy Scout troop. I was even strength training in my last years of high school.

As an adult, I was diagnosed with ADHD. And while exercise is extremely important with that diagnosis, I did not understand how essential it truly was. Because of that absence of understanding, I lacked the motivation to continue my healthy habits into my adult life. Luckily, eventually I was sparked to make a change, and that’s when I realized just how useful exercise and fitness truly was, specifically for my mental health.

I want to help kids understand that exercise and training is important, and that it can be fun and outlet for our daily stressors. I want to help the future generation be strong and healthy!

Debbie M.


I have been in the fitness industry since 2008 and began my career teaching spin and group fitness classes. I loved working with people to help them achieve their fitness goals, so I then went on for my NASM Personal Training certification.

I specialize in high intensity circuit style training as well as endurance and functional training for a wide range of clients. I have experience training those as young as teens up to and including older adults, people recovering from injuries, and pre- and post-natal women.

I incorporate a variety of training methods into each client’s training program based on their individual needs, including bodyweight exercises, plyometrics, and free weights to keep workouts fun and to continually challenge muscles.

I began playing sports and exercising at a young age, so fitness has always been a big part of my life. I enjoy helping people live healthier, happier lives. I really believe that with dedication and hard work you can achieve anything you set your mind to.

For training teens and younger clients, I focus on keeping the exercises fun in order to keep their attention and interest. I feel that if kids or teens can start to enjoy and see the importance of exercise at a young age, it will make it easier for it to become a part of their healthy lifestyle when they are adults. Using a variety of equipment can also help to get teens excited and interested in working out.

In addition to my current certifications, (American Heart Association CPR/AED, ACE Group Fitness Instructor, Schwinn Indoor Cycling, TRX Suspension), I am currently working on my ACE Functional Training Certification as well as my Precision Nutrition Coaching Level 1 Certification.

I hope to be able to further help my clients with new knowledge and skills.
