Introduction
I’ve been a personal trainer since 2010 — this isn’t a job, it’s my purpose. Fitness saved my life, and now I’m paying it forward by helping others transform theirs. I’ve trained clients from every walk of life, ranging from competitive athletes to complete beginners. My specialties are muscle growth, weight loss, flexibility/mobility, and nutrition. I don’t just train bodies — I help rebuild confidence, mindset, and momentum. If you’re ready for real change, I’m here for it.

I never expected myself to be the person who gets excited to work out. I never thought I'd be able to go into any gym, no matter where it is or what equipment they have, and confidently know what to use, how to tackle it, and the proper form needed to walk away knowing I did my best. Rob changed that for me.
Rob isn't someone who just goes through the motions to complete a session. He genuinely cares about showing you how to do things the right way and passing down the knowledge he's gained over his many years to bring you closer to his level of expertise.
Every session, we're trying new stuff, even over two years into it. Rob's always experimenting with new ways to hit certain muscle groups in a way that makes sense for *you* and how your body works. It feels like every time we meet up, we have an incredible session, getting to learn and try new stuff (and sometimes laughing at the things we tinker with), and we walk away feeling better than ever.
I feel better physically. I feel better mentally. I don't know how I'd be today if we hadn't started training with Rob!

I started training with Rob almost 7 months ago during an active ankle injury with a short break for surgery. We trained through my recovery as well. I have a lot of injuries (chronic and new) with restrictions for work. Rob has been amazing at coming up with a new training plan on the fly depending on how I'm feeling and at what stage of recovery I've been in.
His ability and willingness to work with me to ensure that I don't reinjure myself is amazing. His knowledge and expertise is apparent when you see him make adjustments to exercises or come up with something new altogether that works for me.
He has really helped me develop confidence in my strength and form. I can't recommend him enough!

We've been training with Rob for almost two years and in that time we've developed knowledge, techniques, and physiques we are proud of!
Rob shows a real interest in your development that makes it rewarding to train. His bodybuilding creativity and fitness knowledge is apparent from day one and sets him apart from your average instructor. You'll quickly learn what muscles to target, how to activate them, and how to grow them.
Rob takes what could otherwise be a routine, boring workout routine and instead makes it a cerebral hobby. Workouts will use your mind as much as your body. You won't just be throwing weight around, instead you'll be developing connections to individual muscles, building a library of cues, and customizing technical movements.
On top of that, Rob is also extremely genuine, friendly, fun, professional, and flexible! I highly recommend Rob to anyone looking to truly transform the way they approach fitness and bodybuilding.

I hired Rob on May 1, 2023. I didn't know then he would change my body and my life. I had been training seriously for 3 years at that point and was already highly knowledgeable about the foundations of hypertrophy (muscle growth) training and nutrition. I had also worked for 6 months with one of the country's leading experts on female bodybuilding; I hired Rob because in our first interaction, he taught me something I didn't already know. I had considered over 30 trainers at that point and he was the first to teach me something new when he answered my questions.
I trained with Rob 5 days a week for 18 months. In that time, I lost 30 pounds on the scale; my waist went from 30" to 26", my body fat is just around 20%, and I am (pardon the frankness) jacked AF. The thing I enjoyed the most about Rob's training is that I learned how to train myself. As a bodybuilder, when I hit my goal, I'm onto the next area that needs to be brought up or whittled down or whatever and I'm never satisfied. Because of Rob's detailed coaching style (he will go into as much detail as you want), I learned the right way to push myself to continue to develop my physique. I've been training myself for five months now, and I've made substantial gains in that time. I also feel confident training myself because I know how to tweak my exercise selection, form, tempo, rep ranges, programming, and more to continue to get results. I'm a lifetime natural, and my beginner gains are long gone, so this is no small feat.
A lot of trainers can help you lose a few pounds and learn how to lift weights, and if you're looking for that, Rob can certainly help you. He shines in training serious bodybuilders who always expect more. Training with Rob gave me a confidence that will stay with me my entire life. I really can't recommend him highly enough. If you're a bodybuilder and want to take it to the next level, hire him. You won't be sorry. I never was.
