The Science and Methods I Use

Why I Chose These Methods

My motivation is to deliver the best possible outcomes for my clients within the shortest possible time in a supportive and friendly way. Therefore, I only use evidence-based methods that are supported by empirical research.

The Science of Language and Thinking:
Relational Frame Theory (RFT)

RFT is a lab and field-tested theory of how the human mind works. It’s the result of 40 years of research. 

Everywhere humans go, their minds go with them. 

If we understand how our minds work, we become much more effective in overcoming challenges, achieving our goals, and living our best lives. 


We can also better understand ourselves and others and interact with the world more productively and harmoniously. 

RFT enables me to apply interventions, techniques and exercises with precision and help with virtually any problem that involves thinking, feeling, sensing or remembering. 

The Methods I Use

(depending on the client's challenges)

Acceptance and Commitment Training or Therapy (ACT in either case)

‘ACT arguably applies to more types of problems and situations and has consistently provided more good “why” explanations than any other widely used change approach in applied psychology. 

I know how that sounds and I feel a little frightened to say it so boldly—but I stand by it because I believe it is correct.’ 

- Steven C. Hayes PhD 


ACT helps us expand our thinking and feeling, evolve our actions and live better, happier and more fulfilled lives. 

I frequently use simple, practical exercises and metaphors from ACT to help my clients disarm their unhelpful thoughts, change their relationship with their emotions, loosen their attachment to their self-stories, connect to their needs and take valued action based on those needs. 


‘The central shift is from a focus on what you think and feel to how do you relate to what you think and feel.’ - Steven C. Hayes PhD

  • Improving mental well-being (e.g., stress management, anxiety, depression, PTSD, OCD, grieving)

  • Improving social relationships 

  • Finding meaning and purpose and improving motivation 

  • Improving workplace or athletic performance

Applying ACT Beyond Mental Health

What ACT Helps Us Do

Process-Based Behaviour Therapy (PBBT®)

PBBT has been used with individuals and groups across a broad spectrum of issues and has also been employed in organisational and professional contexts. Don’t let the “Therapy” word mislead you.

“PBBT works by fundamentally changing the relationship we have with ourselves and redirecting our behavior towards a more meaningful life.” - 

PBBT provides a comprehensive understanding of how our sense of self is shaped by our experiences, thoughts, feelings, and behaviours and provides guidance on how to change these patterns to promote growth and well-being. 

PBBT is entirely based on cutting-edge behavioural science, specifically on Relational Frame Theory (RFT). 

It has been developed over ten years by Dr Yvonne Barnes-Holmes and Dr Ciara McEnteggart, based on 30 years of their combined experience as researchers and clinicians.
