About Illuminarity

I established Illuminarity Ltd in 2011 to develop my own love of helping people grow and achieve things that they hadn’t thought possible.

I aim to provide an affordable way of improving long term performance, not just short term benefits. Clients come from a range of sectors and use Illuminarity for business coaching, personal development, career coaching and bespoke management training.  

 I work with individuals, teams and businesses in Lincolnshire, Cambridgeshire, Nottinghamshire and further afield. To see how people have benefited, please take a look at the testimonials.  

The name Illuminarity is a blend of illuminate and clarity – illuminating potential and giving clarity on the way forward.
