Executive and team coaching, shaped by 15+ years of senior leadership at Meta and The Telegraph.

Hello

I’m Mazelle Siton, Executive and Team Coach. I’ve spent 15+ years building and scaling teams in high-growth and complex environments like Meta, The Telegraph and OMD UK. Along the way, I discovered the most fulfilling work is helping people step into their power, grow with courage, and find more purpose and joy at work. Today my focus is helping leaders and teams build clarity, confidence and resilience where it matters most.
