He started his career in arboricultural contracting and then consultancy in Dorset and then moved to Surrey and set up SJAtrees in 1995.

He is particularly interested in the historical and landscape value of mature trees and finding practical and pragmatic ways of designing layouts in such a way that they can be retained. Simon has appeared as an expert witness in court cases and at both public inquiries and informal planning hearings.
