Testimonial for Sabine Christelli — Sleep is Your Strategic Advantage
“Sabine facilitated an Influencing Women’s Over Dinner group for Behind Closed Doors recently. I was immediately captured by Sabine's presentation title — Sleep: The Overlooked Leadership Asset — and she absolutely delivered on that promise.
As someone who works with senior leaders every day, I know firsthand that the one thing that gets sacrificed when we're juggling careers, family, relationships, and fitness is sleep. We wear the exhaustion like a badge of honour, when it’s quietly eroding everything, we pride ourselves on; our focus, our judgement, our emotional intelligence.
Sabine brings the science without the overwhelm. What struck me most was her message that practical micro changes can make a measurable difference. No dramatic lifestyle overhaul required. She reminded us to be kind to ourselves and backed it up with evidence that most illness can be prevented with consistent, quality sleep.
If you want to think more clearly, lead more effectively, and genuinely change your life for the better, learn from an expert who makes the science not just accessible but actionable.”
— Donny Walford FAICD, Managing Director, Behind Closed Doors

We look forward to continuing this collaboration.”

“Sabine, thank you so much for your incredible workshop — it was informative, engaging, and so much fun! Our entire team loved having you. The interactive elements and your Sleep Challenge were inspiring, and we especially loved learning about the chronotypes — we’re still comparing notes, reflecting, and implementing changes around them! I’ve already started using many of your teachings, and my focus, energy, and sleep have all improved. Your blend of science, warmth, and practical tools made everything easy to apply. We’re so grateful for the positive, lasting impact you’ve brought to our workplace wellbeing.”

Her calm, science-based approach makes complex principles practical and easy to apply, helping participants unwind deeply — many reporting noticeably better sleep and renewed mental clarity afterward.
Sabine’s sessions combine professionalism with genuine care, leaving our teams relaxed, centred, and re-energised. Her ability to restore both body and mind has made these programs an invaluable part of our corporate wellness culture, enhancing not just wellbeing but sustained performance and rest.”

The practical tools you shared have become part of my daily routine, and my personal “toolkit” now feels complete.

“Sabine’s classes, education, and her beautifully designed Sleep Guide were absolutely excellent! In fact, they were one of the main reasons we chose to book The Reef House — and it was so worth it. Her sessions were brilliant, combining science, practical tools, and deep relaxation in a way that’s easy to understand and immediately effective. We left feeling recharged, sleeping better, and genuinely inspired to keep applying what we learned at home. Sabine’s expertise and warmth made our stay unforgettable — a truly transformative experience in every sense.”
