JR Prieto-Romero, CSCS

I have dedicated the last decade of my life to become the best trainer and person I could be.  I graduated from Oregon State University with a degree in Exercise and Sports Science.  I have been the head trainer and coach at G3 Sports and Fitness and a CrossFit Box for the last few years.  I have worked with a diverse population from youth athletes working on the fundaments of movement science, athletes looking to enhance their performance to the next level and prepare for college, adults looking to recondition their body from a long hiatus or build a healthy and strong foundation, and seniors looking to improve their functional capacity.  As a Certified Strength and Conditioning Specialist, I am the go-to trainer for getting bigger, stronger, and faster across the entire spectrum.   When I am not training, I am working on myself and other projects that could help me improve.  I enjoy training, reading, learning, and doing anything that challenges me physically and mentally.

Devin Shelfer

Certified Personal Trainer (NASM-CPT)

The world of physical fitness has always been an interest of mine. What started as an interest has slowly turned into an obsession as I’ve delved deeper into learning the human body. Growing up I was always involved in some sort of sport or physically exerting program, from football to lacrosse or rugby I could never get enough time testing what my body could do. Going from the world of distance running; competing as a lifeguard and a sprinter, to full time weight lifting has given me a scope of what our bodies are meant to achieve.

Learning to teach others how to step into the world of physical fitness has been the most eye opening part of my journey. Beginning the journey is always an excitingly scary process but every step taken is matched with realizations on just how powerful both your mind and body can be. From lifting your first weight to achieving your first proper pull up there is always something to be tinkered and improved upon.

Matt Enas, CES

I participated recreationally in a variety of sports during my childhood and teenage years but developed a heightened interest in physical activity after watching the 2012 London Olympics. Seeing athletes in peak physical condition performing at the highest level provided me with the motivation to start taking my own exercise more seriously. This eventually led to me to develop an interest in the health and nutritional sciences, specifically as they pertain to alterations in body composition and the role that diet and exercise play in facilitating these changes. My interest in these areas culminated in a four-year degree in Kinesiology, which then paved the way for me to obtain the title of Certified Personal Trainer through the National Academy of Sports Medicine.

I believe that my job as a Personal Trainer is not just to motivate and design programs for my clients, but also to be a source of knowledge in a fitness industry where so much conflicting information exists regarding “optimal” diet, exercise, and lifestyle behaviors. Using the knowledge and experience that I gained in pursuit of my degree and certification, I design programs that are specifically tailored to my client’s needs and abilities. There is no “best” way to exercise or eat – there is only what works and is sustainable for you as an individual. This idea forms the basis for my approach to creating a program for each new client and makes me excited to meet and work with new people and help them achieve the fitness goals they have always wanted to.

Mason Morgan, B.S. Kinesiology, Oregon State University

Certified Strength & Conditioning Specialist (NSCA-CSCS)

Throughout my life I have always been around sports, whether this was playing sports in my youth or coaching sports throughout college. This love for sports led me to earn a Kinesiology Degree from Oregon State University. During my time at Oregon State, I was able to learn under fantastic instructors that led me down the path of personal training. With my degree, I was able to earn my Certified Strength and Conditioning Specialist certification and have been training since. I work with a vastly diverse population ranging from youth building a movement foundation to athletes training to enhance their performance to functional fitness for all levels. 

My goal, as a trainer, is to inspire people to become more active whether this means getting up and walking more or coming into the gym and resistance training. When I am not training, I am teaching at OSU or coaching youth basketball. I enjoy spending time and hiking with my two dogs Maki and Ollie, reading, and playing basketball.

Jayna Davis, BS

Bachelors in Human Nutrition

Certified Personal Trainer

I have always lived an active lifestyle, playing all types of sports as I grew up. Many of my older family members struggled with disease and mental illness. As I got older, I learned how to use exercise and nutrition to prevent disease and help manage anxiety and depression.

I studied Human Nutrition at The Ohio State University and following my graduation I worked as a clinical nutritionist and health educator at Vanderbilt University Medical Center. I continued living an active lifestyle outside of the hospital, training small groups at a local community center. I decided I wanted to spend my life helping others prevent disease and live a healthy life through diet and exercise. I began studying for my personal training certification through the American Council on Exercise (ACE) and became a Certified Personal in October 2022.

My goal is to help you understand how to take control of your own health through small, simple changes.
When I am not helping others I enjoy experimenting with cooking, hiking, playing volleyball, walking my dog, and finding cute coffee shops.


Rebecca Reeve

Certified Personal Trainer

Certified Nutrition Coach

I’ve always enjoyed being active and grew up playing soccer and skiing as a way to connect with my family. In high school, I competed in downhill ski racing. As an adult, I’ve found so much joy in doing step aerobics and I love the challenge of weight lifting.

I attended Portland State University and earned a degree in French before going on to complete a Postbac in Biology. I worked in a women’s health clinic for a few years before having children of my own and nurtured a passion for caring for pregnant and postpartum women. I have been teaching group fitness classes since 2018 and became a Certified Nutrition Coach and a Certified Personal Trainer in the spring of 2023, and I’m currently completing a course to be a Pregnancy and Postpartum Corrective Exercise Specialist. 

When I’m not at the gym, I enjoy spending time with my husband and three children and our cats and dog. Baking is my favorite hobby and I love experiencing the world through travel and food.
