My name is Albert, but most of my athletes and clients know me as Coach AB. I’ve been a trainer and performance coach for over 10 years, dedicated to helping people move better, feel stronger, and thrive in whatever lane they’re in sport, rehab, or everyday life. I got my start working as a PT aide at a sports rehab clinic after finishing my undergrad, learning from a great team of doctors and therapists. That experience shaped how I approach training, blending performance with care and working with individuals from all backgrounds, including post-injury recovery. I moved to Denver to pursue my Master’s in Sport Coaching at the University of Denver, where I had the opportunity to work with high school, collegiate, private, and professional athletes. That time helped me dive deeper into the world of strength & conditioning, sport science, and athlete development and I haven’t looked back since. Over the years, I’ve learned that coaching isn’t about the spotlight, it’s about helping others grow. It’s not always viewed on the same level as medical care, but I believe coaching can be transformative when it’s rooted in trust, education, and consistency. Whether it’s helping someone return from injury, unlock new strength, or prepare for their next season, I coach to help people build momentum toward the goals they once thought were out of reach.

What to Expect From Coach AB
Evidence-Based Programming
I use proven, research-backed training methods to design programs built around your goals, movement patterns, and performance needs. Every plan is personalized, effective, and grounded in data.
Accountability Coaching
When you train with me, you’re never doing it alone. I stay connected with you between sessions, track your progress, and help you stay on top of your goals. I’m here to support you, challenge you, and make sure you keep showing up, even on the days when motivation feels low.

Enjoying The Journey
Training isn’t just about hitting the next milestone, it’s about finding joy in the journey. I help my athletes and clients appreciate the small wins, embrace the challenges, and discover the satisfaction that comes from showing up consistently. When you learn to love the process, progress becomes natural, sustainable, and far more rewarding.
Self Empowerment
My goal isn’t just to coach you, it’s to help you build the confidence to train on your own. I guide you step-by-step until you feel comfortable in the weight room, understand proper technique, and trust your own ability. When the time comes to “graduate” from coaching, you’ll have the skills to move forward independently. You’ll always have access to me for guidance, inspiration, or new training ideas anytime you need it.

AB is the absolute best trainer that we have worked with! He really knows how to bring the best out of his athletes and cares about their total development. You won’t find a more dedicated trainer and coach for your athlete that you can trust to train your son or daughter in a safe and effective manner for their long term development.

Albert is extremely attentive to his clients’ specific needs and works hard to provide unique & individualized training plans. Having known him for almost 20 years both personally and professionally, he never stops learning and is always looking for new ways to challenge himself and his clients. If you’re somebody coming back from an injury or looking to jumpstart your fitness journey, Albert is a knowledgeable guide to show you the way!

I’ve been working with A.B. for a couple of years now, and it’s been one of the best decisions I’ve made for my health and fitness. The progress I’ve made with his support is way beyond what I ever managed on my own. One of the things I really value about training with A.B. is how much he focuses on technique. He’s always making sure each movement is done properly, so we’re targeting the right muscles and avoiding injury. That kind of attention to form makes a huge difference and has helped me build strength in a safe, sustainable way. He also knows exactly how to push you—just enough to keep you progressing, without ever feeling overwhelmed. What really sets A.B. apart is the depth of his knowledge. He’s not just a trainer who shows you how to lift weights—he brings a well-rounded understanding of strength training, biomechanics, nutrition, and recovery. Whether we’re adjusting a program to meet new goals, talking through how diet affects energy levels, or building in recovery strategies to prevent burnout, he always has thoughtful, evidence-based answers. On top of all that, he’s positive, encouraging, and genuinely invested in helping you succeed. He creates a clear plan tailored to your needs and goals, which makes it easy to stay motivated and consistent. If you’re looking for a trainer with real expertise who also brings great energy and support to every session, A.B. is the one to work with. I can’t recommend him enough.

I've been training with Albert for about 3 years now. He is always proactive about working around my physical limitations (on-and-off lower back pain) while also designing programs that increase strength and mobility in those same areas. I have been consistently surprised at how much strength I've gained working with Albert, but also how much less pain I experience on a day-to-day basis because of his attentiveness to the training program and how it's working for me. Albert is friendly and motivating, but always focused and ready to train with a purpose. 10/10 highly recommend 🙂

Albert is an AMAZING athlete and trainer! This guy is extremely positive so even all the days you don’t have the energy for a positive mood, he’s got enough positivity for the both of you to get your spirits lifted for a workout! Also my favorite part is that he’s been a Physical Therapist Aid (PTA) for 8.5 years (this is how I met him btw, I was a PT patient) so he knows the best workout that specifically meet your needs and knows how to keep you on point with teaching you how to use correct form to keep you safe and so you get faster results than if you trained on your own without professional help. Thank you for all your help Albert, you’re the best and have taught me a lot and have help me achieved my body goals!👏🏼 *I’ve seen great results especially in my abs, glutes and legs but it’s only been a few months so I’m waiting for that 1 year mark to submit a before and after photo!

We first met AB 3 years ago, from day one he's always been about the care, safety and health of my daughter. He took the time to learn about her and her strengths and weaknesses before doing any type of workout. I truly appreciate the fact that he's understanding and aware not all athletes are the same. He’s been able to help build strength in her knees as it's been bothering her (growing faster than her body can keep up with). You can tell he has a pure love for helping those build not only their strength, but their confidence as well. He celebrates the small wins along this journey as it's an actual journey. He breaks it down so that his clients of all ages are able to understand why he has them learning proper form before picking up any weights. Safety is his number one priority. He'd rather start light and work your way up. I HIGHLY recommend him for your student athlete and personal trainer as well. I'm so glad we crossed paths when we did, we consider AB family and truly appreciate and support all he's done and continues to do for and with us!!
