Awards & Recognition

Darren is known to go ‘over and above’ for clients and they often say how enjoyable it is working with him. 


In his free time, Darren chairs the governing body of his children’s school. Meanwhile, after (responsibly) enjoying real ale for many years, a gluten allergy forced Darren to explore the world of artisanal ciders. He continues to face this challenge with stoic resolve.
