About Yolanda

Thirteen years inside the pressure I now coach people through.

My story

From the trading floor to executive coaching.

I am a Cambridge-trained advanced executive coach working with leaders and high-performing professionals in complex, high-pressure environments, helping them develop clarity, confidence, resilience and sustainable performance.

“It was exhilarating. Until it wasn’t.

Before becoming a coach, I spent 13 years in global banking, including a decade in derivatives and FX trading. I managed teams, navigated fast-moving markets, and delivered results in roles where the expectations never dropped.

Experiencing burnout during this period fundamentally reshaped my understanding of performance, leadership and resilience. It led me into executive coaching with a deep appreciation for the internal demands placed on high-achieving professionals, and for what it takes to perform at a high level without breaking.

My approach

Coaching that works on thinking, and on the physiology underneath it.

My coaching combines deep, reflective executive coaching with a practical, performance-focused approach. Together they help leaders think clearly under load, make better decisions, and hold their presence through sustained demand.

Executive coaching usually works on thinking. I also work on the physiology underneath it, because judgement degrades before anyone notices it has.

Alongside reflective coaching, I draw on evidence-based emotional regulation, including somatic and acupressure-based techniques, refined over eleven years of practice with professional clients to reduce overwhelm, regulate emotional responses and build resilience.

The goal is not simply to cope, but to lead well under pressure that does not let up.
