About me
Leadership Coach | Impostor Phenomenon Specialist | Positive Psychology Practitioner | Senior Practitioner EMCC
Feel like you're faking it - and afraid of being found out?
Despite a track record of success, do you secretly wonder if you’re good enough?
You're not alone. I specialise in helping high-achieving professionals and leaders quieten their inner critic, feel more confident in their abilities, and overcome persistent self-doubt - including the kind that comes with impostor feelings or neurodivergent thinking.
Common experiences I help with:
- Feeling like a fraud despite positive feedback and achievements
- Dismissing your accomplishments or minimising your role
- Overthinking, perfectionism, or fear of failure
- Reluctance to pursue promotions or stretch opportunities
- Negative self-talk and internal pressure to “get it right”
- Feeling like you “should” have it all together, but don't
How coaching can help:
My coaching programmes are tailored to support you in:
- Managing impostor thoughts and quietening your inner critic
- Building real, lasting confidence in your abilities
- Strengthening your resilience and leadership mindset
- Feeling more comfortable being seen, heard, and stretched
- Pursuing growth with clarity and self-trust
Whether you're an established leader or an emerging one, we’ll work together to shift unhelpful thinking patterns and unlock the presence, impact and confidence you already have - but may not yet fully see.
For organisations:
Impostor feelings and self-doubt can hold back even your most talented leaders. These internal blockers can show up as perfectionism, overworking, reluctance to step up - or burnout.
I work with companies to support high-potential individuals to:
- Recognise unhelpful patterns
- Set intentional development goals
- Lead with greater ease, confidence, and authenticity
My approach:
Every client is different, so I take a personalised approach, drawing on:
- Coaching psychology and evidence-based tools
- Original research into high-achieving behaviours
- Deep experience supporting leaders with impostor feelings and mindset work
Together, we’ll co-create a path towards genuine confidence and meaningful leadership growth.
