About
I don’t believe in one-size-fits-all training. Every client I work with gets a plan built around their goals, movement patterns, and lifestyle and not generic workouts pulled from a template. My background as a former collegiate athlete and seven years in strength and conditioning has taught me how to coach with intent, precision, and long-term progress in mind.
I specialize in getting people stronger, more resilient, and more confident under the bar, whether that means preparing for competition, building serious strength for the first time, or training pain-free. I coach competitive powerlifters, athletes, and everyday people who want results without wasting time or risking injury.
What sets me apart is attention to detail, honest coaching, and consistency. I track progress closely, adjust programs based on real feedback, and educate clients so they understand why they’re doing what they’re doing. If you’re looking for a coach who takes your training seriously and is invested in your long-term success and not just quick wins, I’m the right fit.

Mario is the best trainer I have had over the years. He is motivated to understand my needs and adjusts my routines accordingly. I love that he has a contagious, “go get’um”, attitude that compels me to be ready for every session. He is constantly checking (via Facetime) my form as I perform his exercises. I wholeheartedly recommend Mario as a personal trainer.

Mario is an outstanding coach. His programming is smart and truly individualized, his feedback is clear, and he knows how to push intensity without running you into the ground. Even when we’re not training in person, he provides a complete plan - exercises, sets, reps, and target weights - so there’s zero guessing.
After a year working with Mario, I’m substantially stronger, more consistent, and more confident in all my lifts. I started 2025 not even knowing how to deadlift - by the end of the year I totaled 1,000 lbs across the big three - something that absolutely wouldn’t have happened without his guidance.
If you want real progress and trustworthy coaching, work with Mario.

Unbelievable time with Mario as a coach so far. His communication style is easy, attentive, and straightforward. His ability to help you understand what’s needed to accomplish the task at hand is crazy and he can’t help but pepper in his passion for all things training. His cues are thoughtful and openness to questions about programming as well as exercise selection make going to the gym enjoyable (even when it gets hard). He’s striving to build that mental toughness in you as much as the physical strength. There’s always an uncanny method to his madness that complements his eye for detail. Mario is knowledgeable on general fitness all the way up to different training philosophies, methodologies, and he’s willing to explain schools of thought in ways that are understood by anyone new or seasoned in working out. He keeps up to date with advancements in the powerlifting community to ensure he gets the most out of his athletes. He can bring anyone to the podium that’s willing, I’m excited to see what he cooks up next and you should be too!

Mario has helped me so much in my day to day life. He truly knows what he’s talking about when it comes to training. Every time I feel some sort of discomfort in the way I am lifting, he assesses the situation with such speed and helps me correct my problem instantly. It’s pretty insane how on point he is when it comes to training. I’ve stated how I’ve wanted to grow bigger legs and bigger arms, he has totally fit my program to grow both twice as fast as I could ever on my own. He’s helped me with my confidence and helped me with my work ethic. I get so many compliments on my physique and I always tell people about my best trainer Mario!

Working with Mario for the past year plus has been a game changer for my health. He listens closely, understands what drives me, and builds a program that fits my life and keeps me motivated. On top of that, his great personality makes every session something I genuinely look forward to - he’s always in a good mood, fun to be around, and brings an energy that makes hard work feel surprisingly enjoyable.
In this time, I’ve lost weight, gained muscle tone, and - most importantly as a menopausal woman - boosted my bone density. Mario’s expertise, encouragement, and positive spirit have pushed me further than I thought possible, and I recommend him wholeheartedly to anyone serious about making real, lasting progress.
