Since his horticultural training at the prestigious Merrist Wood College over 28 years ago, he has built an award winning career in landscape and construction that extends across the UK and abroad, encompassing private gardens, tourist and golf resorts across Europe and the Caribbean, as well as numerous Garden Shows.  This breadth of experience, which has expanded his garden knowledge to include semi tropical and tropical disciplines, allows him and his team of specialists to execute complex garden designs with the highest of sophistication.
