About Illuminarity

Ruth Cass, Accredited Business Coach, Career coach, and Management TrainerI established Illuminarity Ltd in 2011 to satisfy my own love of helping people develop 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.
