Joanne Castillo of Infalible Fit

Meet joanne

Founder & Head coach

Joanne is a holistic strength coach, proud LGBTQ+ entrepreneur, and a 15-year Air Force medic veteran with a passion for helping busy moms prioritize their health and personal growth. Infalible Fit is proudly lesbian-owned, built on the belief that strength, authenticity, and belonging create the foundation for real transformation—inside and out.

Joanne’s journey began in a place many moms can relate to feeling stuck, overwhelmed, and unsure of how to reclaim her health and happiness.

For years, she struggled with yo-yo dieting, believing that being overweight and unhappy was simply her reality. She faced battles with self-esteem, self-love, and respect, compounded by unhealthy coping habits. Her wake-up call came with a diagnosis of pre-diabetes and high cholesterol, pushing her to take a leap toward change.

At 35, she hired a coach and lost 50 pounds—a transformation that went far beyond the physical. She became stronger in body and mind, gaining clarity on how deeply unhappy and insecure she had been. Through deep inner work and a commitment to personal growth, Joanne not only transformed her health but rebuilt her confidence, mindset, and habits.

Today, Joanne brings her unique perspective and experience to moms who are ready to rediscover their strength—inside and out. She believes true transformation comes from changing your mindset, habits, and lifestyle alongside your body. Her mission is to help LGBTQ+ and allied moms feel strong, confident, and powerful in every part of their lives.

Outside of coaching, Joanne is a proud new mom, boxer at heart, and adventurous foodie who believes in living fully both in and out of the gym. As a masc mom and veteran, she brings a grounded, no fluff approach to strength training while creating a space for moms to show up as their whole selves. Whether she’s lifting or helping a client rediscover their strength, Joanne’s passion for empowerment and authenticity shines through every step of her journey.
