Dennis was born in Wellington but, for most of his life, has lived in Christchurch. From an early age, he remembers doing sketches and showing an interest in art.
After doing a course in graphic design, he decided to specialise in photographic art.
This involves transforming photographs of people of all ages, animals both wild and domestic into exquisite life-like pencil/graphite portraits.
A fellow artist and art tutor, Ron Naylor taught him the necessary skills which have been developed over many years.
He pays fastidious attention to detail and commissions are a regular part of his work.
