Hi, I'm Cass

I'm a clinical & coaching psychologist from Australia, now based in London. I work with ambitious high achievers & small business owners who struggle with self-doubt and imposter syndrome and who know the problem runs deeper than just their 'mindset'. We do the inner healing work to cultivate genuine, lasting self-belief and self-trust so that you can stop self-sabotaging and achieve the results you're capable of.

  • Stop second guessing every decision

  • Break the perfectionism / procrastination cycle

  • Overcome your resistance to visibility and self-promotion

  • Free yourself from the paralysis of overthinking

  • Achieve success without burning out

  • Trust in your vision and values to live a purposeful, meaningful, fulfilling life
