Sleep Medicine Educator, Performance Coach & Fitness Professional
Oxford-trained sleep specialist helping people translate the science of sleep into healthier habits through evidence-based coaching, movement, and behavioral sleep medicine.
Mission
I believe sleep is one of the most powerful and misunderstood foundations of health.
My mission is to make the science of sleep practical, accessible, and actionable through evidence-based education, movement, meditation, and behavioral coaching so people can thrive in every season of life
What Working Together Looks Like / Why Sleep Matters
Build the Foundation of Your Health
Sleep isn't just about the night. It influences your brain, metabolism, mood, exercise recovery, relationships, and long-term health.
Evidence Over Guesswork
Learn evidence-based strategies rooted in behavioral sleep medicine, not social media trends, gadgets, or quick fixes
Understand YOUR Sleep
Together we'll identify the habits, beliefs, lifestyle factors, and medical considerations influencing your sleep so your plan fits your life.
Sleep with Confidence Again
Move beyond constantly checking the clock, chasing wearable scores, or worrying about every bad night. Learn to trust your body's ability to sleep again.
Build Habits that Last
My goal isn't to help you sleep well for a week. It's to help you develop lifelong habits that support resilience, performance, and healthy aging
