About
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 don’t usually write reviews, and I’ve never really been one to use online services, but after moving from Sacramento I needed to find a new personal trainer to keep me on track with my fitness journey. I wasn’t sure what to expect, but after meeting Rob I can honestly say my experience has been better than I imagined.
What stood out to me right away is how genuine his approach is. Rob doesn’t just throw a workout at you—he takes the time to understand your goals, your limits, and what really motivates you. He’s patient but also pushes me in the right ways. I’ve had personal trainers in the past, but in just a few sessions with Rob I felt like I learned more and made more progress than I did in a full month of training 5 days a week with my last trainer.
Another thing I really appreciate is how much he focuses on the “why” behind the exercises. Instead of just counting reps, he explains how movements connect to my goals, how to do them correctly, and how they’ll help me long term. That kind of teaching has kept me consistent and made me more confident even when I’m working out on my own.
Most importantly, with Rob I don’t feel like just another client—I feel like a person he genuinely cares about helping. He checks in, pays attention, and makes adjustments that actually fit me, which shows he’s invested in my success. That level of care and attention is rare, and it makes a huge difference.
If you’re looking for a trainer who truly cares, knows his stuff, and will actually help you see results instead of just running you through a generic workout, I can’t recommend Rob enough. He’s the kind of trainer that makes you want to show up and put in the work, and I’m glad I found him here.

Rob is outstanding on all levels. I found him here on Thumbtack last year and gave him a try based on the reviews. Rob is not just a good trainer, it's how he trains. I've been working out for years and had a trainer before, but Rob finds muscles I didn't know I had! He knows the body so well that every exercise movement is unique and targets specific muscles to maximize the workout. Beyond his knowledge, he clearly loves what he does - it's his passion. This is what helps fire me up and motivates me. At 62, I didn't think I could get my 35-year old body back, but that's what's happeningl Thank you, Rob!

Rob is absolutely amazing! My daughter had been sick in bed recovering for months and Rob got her moving and gave her back great confidence. He truly cares about his clients and goes above and beyond to help. My daughter is now greatly improved and is back at college - still training with Rob online. He is a very knowledgeable trainer and also an extraordinary and kind person. We feel so lucky to have him get us into shape and restore confidence and health to my daughter. Thank you, Rob!!

Rob is an excellent trainer! He is very personable, motivating and friendly. I was a college athlete with some knowledge of lifting and training. He helped me organize and clean up all my lifts and routines. He has experience with all levels of clients.
Rob created a customized program for me that he adjusted as he learned more about what worked for me personally. It is obvious he takes a lot of time and effort into making the training plan for each client. He is creative and varies the workouts.
I can truly feel a difference lifting since we started working together. I would highly recommend him.

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!
