I spent the last decade becoming an expert in sustainable high performance for professionals.

My background is as a client-facing partner and a People Partner at KPMG.

I have worked with some of the biggest companies in the world, and some of the fastest growing startups.  

I have coached or mentored over 250 people, and worked with over 100 senior executives. 

I have used what I have learned to significantly increase my own impact, income, and free time.   

I have significant executive experience, having held the positions of both Chief Operating Officer and People Partner for a major division of KPMG. I understand the demands and challenges faced by those with significant leadership responsibilities.  

I also understand how to deal with and lead through change. I significantly improved employee performance, employee retention, staff survey results, and Inclusion, Diversity and Equity metrics. This was alongside a doubling of the size of the division over four years.

I now coach senior executives to help them achieve even greater success.

I also write and speak about how leaders, professionals, and founders can be happier and more fulfilled by changing how they work.
