Guy M. Massi, SSC, SCS, CES, CFSC, CTBS, CSSN (Director of Operations, Athletic & Curricular Development)

Guy Massi is a former competitive athlete and the husband and father to a household of competitive athletic boys of his own, currently competing at various levels youth thru collegiate. More than twenty years ago, he started the individual performance coaching of athletes and clients part-time as a way to supplement his income and is now a locally, nationally and internationally recognized speaker, trainer and coach. In his more than two decades in the field, he has been developing athletes and fitness clients of all ages and levels, and has or now serves as an industry resource to many local and national athletes, teams and organizations including yet not limited to; NFL player agent Kevin Fitzpatrick, the Hong Kong National Ice Hockey Team & Academy program director, FHL Hockey, Tsunami Bar and many others. More than merely understanding the physiological requirements associated with developing performance in athletes and clients, he is truly a master of recognizing and nurturing the emotional component. Suffering the loss of both of his parents by the time he was 18, Coach Massi has turned various challenges into victories, and has learned the art of perseverance. Guy said, “Due to seemingly insurmountable challenges in my teenage years, I once ballooned to over 300 pounds – and it was all emotional! I had two options; either succumb to defeat, or overcome and serve as an example to others. – I chose option 2”.

He is the author and keynote facilitator of the HyperNova Athletic Development & Functional Fitness System© bearing inclusive curricula for speed, strength and power, agility, balance and mobility, functional fitness, explosiveness, proprioception, and energy system training. He is a pioneer in maximizing fitness and athletic development within systematic and programmatic time constraints thru the use of signature protocols and methodologies. He is a persistent learner and routinely works with doctors and physical therapists in rehabilitating athletes and clients, and specializes in medically indicated and supervised Return-to-Play programs. He is hungry for knowledge and maintains industry relevance thru continuing education and writing for peer review. Coach Massi states, “I’ve learned from my own mistakes and ‘failed experiments’ and thusly remain in a constant state of learning. I believe I’ve found what foundationally works for building superior athletes and clients, and believe in meeting people where they’re at – then challenging them above and beyond what they ever thought they might accomplish. One thing that is a constant however; nothing substitutes for persistent, diligent effort – also known as HARD WORK! Really, at the end of the day we are developing future moms, dads, husbands, wives and professionals or reinforcing one’s current responsibilities and obligations. The performance development aspect is second nature at this point, while the greatest challenge can be my primary goal of; actively lending to the development of contributory members of society who excel in sport, work and life.”

Coach Chris was raised in Carmel New York and is a product of the MMSC methodology.  Formerly a two sport athlete (baseball and football) he settled into football and enjoyed an illustrious high school football playing career at Carmel High School.  Playing and starting at both the Fullback and Inside Linebacker positions, he held impressive offensive and defensive statistics that yielded team, district and section honors.  Known as a punishing force on both sides of the ball, Chris was recruited by a number of prestigious football programs/colleges, and decided to pursue the more modern major of Health Fitness Management found at Alfred University in upstate New York. (A degree designed to prepare graduates for all aspects of strength and conditioning, clinical exercise, fitness, personal and athletic development, sports operations and related business minutia).  While playing at Alfred, Chris once again proved to possess the skill set required to get utilized on both sides of the ball at the Fullback and Inside Linebacker positions, enjoying a four year “Iron Man” collegiate career.  He also joined his team in winning an Empire 8 Championship and coveted “ring” while on the road to their National Championship run.  While completing his degree, Coach Chris interned with the University’s Strength and Conditioning department working with both athlete and non-athlete populations.  Upon graduation, Chris completed an internship at Stony Brook University working with Women’s Basketball and Lacrosse, Football, Baseball and other integral competitive sports teams.  Now back at home, Coach Chris brings his talents to “the floor” at MMSC under the direct mentorship of Coaches Massi and Machado as he insures the best possible training and developmental experience for every athlete and client that he coaches.

“After participating in some uninspiring training routines at a variety of locations, we were lead to Massi-Machado Strength & Conditioning thru their affiliate Physical Therapist. Coaches Massi, Cascioli and Machado met with us to establish our training goals and then proceeded to put our team through their rigorous paces. We quickly found the coaches to be superior to any other trainers we had previously encountered and proved to be light years ahead in their methods and knowledge. We were impressed with their implementation of a sport specific program. Rather than utilizing a normally encountered generalized approach, Massi-Machado administered a program that challenged our players. This translated into highly evident gains in speed, power and agility…a requirement to compete and win on the field. Additionally, our team experienced a sense of enjoyment, accomplishment and bonded as a result of the training.”
Robert Leff, Manager, FC Somers Galaxy

“I knew nothing of Sports Performance Training and nearly dismissed the concept when I first heard of it. I thought all of the best football players were made through skills practice on the field. I sent one of my daughters to dance lessons to be on a dance team and my oldest son to instrument lessons to play in a band. Yet, I was just telling my other son to step on the field and play football in hopes that he would somehow miraculously become a football superstar. I decided to give the class that Massi-Machado Strength & Conditioning offers a try for my son’s football program. Great price or not, they have developed my son in ways  I never thought possible. I am now actually able to comment on the fact that he is stronger, faster and more agile. Before, there wasn’t any of that to even make a comparison. Now we routinely obverse results. He is now more generally confident and also remains academically responsible as a result of their staff charging him with his personal development and home responsibilities. He and I both have a great respect for their programs.”
