Everything we do comes down to one simple belief: that success is curated from the inside out. It is not only the ability to build the life you want, but also the ability to enjoy that life. High achievers are maximisers.

Real confidence, fulfilment, and success don’t come from achieving more, but from creating space to live and lead with purpose.

If on the surface you look like you have it altogether, but the silent voice of self-doubt plagues you, you’re in the right place.

Therapy for high achievers

you’re not looking for therapy.

You’re looking for transformation.

In therapy, our team of Psychologists are experts in Autism and ADHD, and know how to blend science with humanity, creating the structure that the neurodivergent brain often craves. We are pragmatic thinkers, and work incorporate the impact of neurodivergence on mental health and self-esteem, as well as performance and executive functioning.

In assessments, we are NICE compliant and take our time to understand your unique make-up, digging into a thorough history and delivering clinical excellence with accuracy. It is never a yes/no diagnosis, but about giving you a roadmap to better understand how you are wired.

Therapy and Assessments for Autism and ADHD

If you know that you are capable, but the way your brain is wired makes the path to your goals harder than you think it should be, you may be neurodivergent.

Our Gold-Standard ADHD and Autism assessments

for children, adolescents and adults.

Are rigorous, compliant with NICE guidelines, widely accepted across the UK, and generally available within 4 weeks.

meet the founder

I’m Dianne,

a clinical psychologist and the founder of Sage Psychology

I am down to earth, slightly irreverent, deeply relational, and I don’t take myself too seriously. My passion for working with high-achievers started with my own story. Despite looking as though I had it all together, anxiety and self-doubt were in the driver’s seat for a long time. I was cycling in and out of burnout every 2-3 years.

I relentlessly pursued success at the expense of myself.

I had built the life I wanted, but wondered why I couldn’t enjoy it as much as I thought I should. I started to learn that the pursuit of success often isn’t what we hope it will be. We pursue it for how we think it will make us feel. Fulfilled. Competent. Content.Only to reach an anticlimax when we get there. And I have since seen the same mechanism in hundreds of high achievers. We are all looking for some version of a life that feels meaningful. And while maximising our potential is important, that’s only a small part of the journey. The rest of it is learning to build a deep seated inner confidence that allows us to align ourselves with our values, and become present to each moment. When we learn to live and lead ourselves with purpose, the fulfilment starts to follow.

If you are a high achiever who wants to maximise your potential, this practice was built for you.

Our team

We’re a professional, down-to-earth, and compassionate team.

Finding the right therapist is the most essential part of therapy. Every member of our team is passionate about working with high achievers, or Autism and ADHD - some work with both. We’re a team of specialists, rather than generalists, and each of us has specific focus areas that we have built a deep knowledge in. We will match you with a specialist for your difficulties, so that we can offer the highest quality of care. Based in Wimbledon, Epsom, Crouch End, and online, we would love to hear from you.
