Unleash your power, purpose and potential.

At Mile One Coaching, I’m all about helping you own your sh*t and step into your highest potential—whether that’s in business, life, or somewhere in between. If you’ve ever felt like you’re spinning your wheels, stuck in that frustrating loop of “almost there,” trust me—you’re not alone, and you’re definitely not meant to settle. I’ve spent decades working with leaders, entrepreneurs, and go-getters like you to uncover what’s holding them back and rewrite the rules.

More About the Event

Mental Fitness

Mental fitness is your ability to handle life’s challenges with a clear, positive mindset instead of getting hijacked by stress, doubt, or overwhelm—and just like physical fitness, it takes consistent practice. The Positive Intelligence^® Program helps you build the mental muscles to quiet negative self-talk, strengthen resilience, and show up as your best self with just 15 minutes a day for 6 weeks—because real transformation happens when you train your mind to work for you, not against you.
