General  Manager


My name is Anthony and I am a certified personal trainer through “Elevated Learning Academy.” I first decided to become a personal trainer a few years ago, when I started Muay Thai. I found out every week they do a 5k run, and I remember being so nervous because I wasn’t sure I could do it. With the support of my group I did make it and 6 months later I ran my first marathon. It felt so great to accomplish something that I never thought I would be able to do, and I decided to get into an industry where I could help others feel the same way.

I started off my passion for training as a group instructor at Southpaw and have now been given the opportunity to focus on personal training. I don’t want people to see exercise and nutrition as a punishment but a tool to enjoy every day to the fullest. I’ll admit that when I first got into fitness, I approached it with the wrong mentality. I had to watch a motivational video every day just to get myself into the gym, because I saw it as something I had to do. Now I try to lead a good example by showing that I eat healthy (but still enjoy goodies from time to time ?) , exercise, push myself, and enjoy every second of it.

The one thing above all that gets results is consistency, so it’s important to me that everyone I work with enjoys their time and takes away something new to improve their skill. Cause who says sweat and smiles can’t happen at the same time?!?!

Kids Boxing Coach

Axel began his lifelong love affair with boxing as a teenager, somewhere in the late 80’s. A respectable amateur run, and a short stint in the semi-pro “Casino Circuit” in the 90’s followed. Since then, he has amassed a world of experience as a non-combatant citizen. Axel studied Elementary Education at the University of Calgary and has had success as a writer and publisher, as well as a myriad of other careers. 

As a dad of two and a former athlete, Axel understands the importance of getting kids moving, as well as keeping them interested in the sport. Having seen action in all aspects of boxing, from inside the ring, to coaching and judging, Axel has a wealth of knowledge and experience to help aspiring boxers and newcomers alike. He has been lucky enough to coach kids and beginners at Southpaw for several years, and plans to stay until he goes out like Mickey in Rocky III.”

Beginner Boxing Coach “The Mongoose”

Hey, it’s coach Terence and I’ve been boxing for 7 years with the aim to go pro. I’ve had 21 fights and have gained experience from across Canada. Aside from boxing, I enjoy hiking, biking, and drawing. 

Back in Nova Scotia, I had a colleague who told me he used to train at Southpaw Boxing here in Calgary, so when I moved to Alberta I set out to find it and didn’t stop looking until I had. In 2020, I took up the job of coach upon request and I’ve been giving it my all since.

I teach the beginner’s boxing class at Southpaw Family and fitness, where I strive to push my students to improve, teach self-discipline, and instill a love of physical challenge.

Boxing and Training Coach

Hello, my name is RJ and I am very blessed to be a part of the Southpaw family

I am currently taking an undergrad in business and aiming to specialize in accounting. I have always been an active person, being the hyper active kid in that family I have played and joined many different sports. From soccer, to track and field, to junior high and high school basketball team, bodybuilding, and CrossFit.

Then one day I decided to learn the sweet science I stumbled upon southpaw, and ever since that day I’ve been hooked. The study of fighting, learning about my inner self mentally and physically, to push the body I never thought possible. It’ll forever be a continuous learning, and I don’t want to stop.

I hope one day you’ll be able to experience what I have experienced, a choice you’ll never regret. Be at your best shape and reach your highest potential!

Now let’s put work in.
