Who We Are

Dr. Katie Heath-Tilford
Director of Services

Katie Heath-Tilford is a psychologist and founder of Thinking in Colour and Optimise, known for integrating psychology, technology, and business strategy to create transformative programmes for individuals, couples, and organisations.

With a Doctorate in Psychology and a Master’s in the Psychology of Education, Katie’s research redefined trauma as complexity — exploring how patterns of relating and belief systems shape our capacity for growth. Her work with EMDR (Eye Movement Desensitisation and Reprocessing) informed new ways of integrating evidence-based therapy within modern, outcome-focused frameworks.

A recognised educator and contributor with EMDR Focus, Katie has played a key role in refining approaches to complex trauma and high-intensity presentations. Beyond her clinical expertise, she draws on years of experience in business, marketing, and start-ups, giving her a distinctive ability to bridge psychological insight with strategy, innovation, and real-world leadership.

Katie’s work is defined by clarity, creativity, and compassion. She partners with clients and teams to translate psychological understanding into practical growth — helping people move from complexity to clarity, and from clarity to measurable, meaningful change.
