Performance & Mindset Coaching with Katie Costello

Unlock Your Capacity, Achieve Your Goals, and Reclaim Your Life

High achievers often find themselves overwhelmed and consumed by their workload—constantly distracted, stressed, and feeling like they can’t catch a break. If you’re caught in this cycle, always striving for success but sacrificing your peace of mind, it’s time to take a step back and recalibrate.

Performance & Mindset Coaching is designed to help you increase your capacity, achieve your goals, and find greater happiness—all without sacrificing your personal life or well-being.

I believe that success shouldn’t come at the cost of your well-being. My mission is to help driven professionals regain control of their work and life by creating clarity, balance, and fulfillment. Through mindset shifts, strategic performance coaching, and a focus on sustainable growth, I guide you to excel in your career while maintaining the space and energy for what truly matters—leading a life that feels both successful and deeply satisfying.

Welcome! I’m Katie Costello


This coaching is for those who want more out of life but feel trapped in a constant state of stress and distraction. Through my coaching, my clients have been able to:

  • Reconnect deeply with their spouse and loved ones

  • Hit record-breaking sales in their careers

  • Gain recognition and respect in their company or field

  • Increase their capacity to handle the demands of life and work

  • Become proactive rather than reactive, leading with confidence and intention

  • Delegate effectively, creating more time and space for what truly matters

  • More Capacity for Life: Handle more without feeling overwhelmed or depleted.

  • Proactive Leadership: Lead your life and work from a place of calm, clarity, and confidence, not from constant reaction to stress.

  • Autonomy and Freedom: Detach from the identity of needing to be a stressed mess in order to be successful, and reclaim your freedom and happiness.
