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.


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 enjoys combining two of her passions, fitness and children, as a trainer at Energetic Juniors! 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.

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.


Growing up, Chao took up playing in multiple sports teams on a high school and collegiate level as an outlet to managing adolescent obesity. Her passion in athletics led her to pursue a Bachelor’s degree in exercise science, with the intention of helping the general population bridge the gap between health and fitness.

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.”

Jerome P.


Jerome has a Bachelor of Science in Sports Science. He was a former High School PE teacher, then moved to the Fitness Industry for the past 12 years. He started as a fitness coach and then became a Fitness Manager, leading a team of Personal Trainers. He was also an Internship Supervisor which educated college student about fitness and exercise. In college, one of his thesis papers was about Talent Identification, which helps identify for kids/
teens as to what sports they can excel in. He always loved sports. He played basketball for his High School team for 2 years which helped give him the drive to pursue fitness as a career. Jerome believes in the quote “Mens Sana In Corpore Sano” which is a Latin term for “A Healthy Mind in A Healthy Body”. He is very passionate in helping people — especially kids — achieve their fitness goals and to educate them about the importance of exercise.

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.

Chris B.

ACE Certified Youth Personal Trainer

I am an ACE certified youth personal trainer, with specialties in youth fitness, functional training & group exercise. I earned my B.M. in Music Theatre from Rider University and moved to NYC 7 years ago. For the past 5 years, I have been a fitness professional. Movement has always been a part of my life. I grew up with ADHD and always had an excess of energy I didn’t know what to do with. But whether through team sports, dance, fitness or Alexander technique, I was always able to build & find community. As I got older, I wanted to re-create and share that community with others. In high school, I worked at my local YMCA as a summer camp/after-school counselor teaching children aged 7-18 through various sports and team building activities. I also designed and implemented a theater/dance curriculum that I oversaw through my 4 years in high school. In my acting career, I always found myself leading/organizing a group fitness class among my peers. The goal is a judgement free, safe space. that encourages exploration and fosters creativity. I invite failure, because I understand this is how we learn and grow.

Maurice C.

Certified Youth Fitness Coach, Boxing, Yoga and ACE Certified

Objective: Impower, Inform, Inspire

Historical achievements: Former Wellness In The School Coach, Rockwall Instructor, Cancer and Exercise Specialist, Yoga Instructor, Pilates Instructor, RKC Kettlebell Instructor,  MMA Coach, Boxing Coach, CoreFirst Coach, Olympic Weight Lifting Coach, TRX Group Fitness Instructor.

What you should know: As a Coach I do not take on “clients.” I call the people I work with athletes and apprentices. Every child has an athletic nature sometimes it just takes a wee bit of tutelage to uncover. I teach through play while providing only positive reinforcement. In a parent’s eyes children are the most precious part of themselves and to this I would agree. I acknowledge the awesome responsibilities of a Coach and give my pledge to offer world class service to the mini versions of you.
