Movement is everything — it allows your mind and body to connect, for you to feel your strengths and weaknesses, to clear your mind (become selfish), and listen to your breath. Movement keeps you healthy both physically and mentally. I help my clients find the right type of movements for them depending on their goals, age, and activity level — ultimately leading them to become stronger and more successful in their lives.
Food feeds your movement — what you put into your body will determine your success. I love to educate clients on consuming whole foods that make them thrive and feel their best! Food helps with recovery, sleep, stress, and is 80% of your results. Everybody is different and requires a different recipe. Learn to live life well, whatever that may look like for you!

My interest in training started while working in marketing with the Sarnia Sting in the OHL.
