My journey began with sports like hockey and collegiate tennis, where I learned the dedication it takes to push physical limits. Along the way, I faced multiple injuries—broken bones, torn muscles, ligaments, chronic knee pain, and hip instability—which taught me the frustration of feeling trapped in a body that doesn’t always cooperate.
Later, life brought more challenges: chronic burnout in high-pressure sales jobs and hormonal imbalances affecting my weight and energy. I tried every extreme—daily hours of training, restrictive diets like veganism and keto, intense weightlifting. While these approaches produced results, they weren’t sustainable and led to added stress, burnout, and less joy in life.
After hitting multiple rock bottoms, I knew I needed a new path—one where I could let go of control, enjoy exercise without burnout or injuries, and eat well without obsessing. Through years of self-care, reflection, and research, I found a balanced approach, blending science and holistic practices that helped me regain my strength, alleviate pain, and find peace in wellness.
I founded LumiSoul out of a desire to serve others, helping them navigate their physical challenges while nurturing mental, emotional, and spiritual growth. With integrity, empowerment, and compassion at the heart of our mission, we’re here to support true wellness—a life of strength, resilience, and purpose.
At LumiSoul, integrity, empowerment, and compassion are at the heart of all we do, ensuring each client feels fully supported and valued on their journey.
