DEREK McFARLAND

Position:

Surveyor/Inspector


Derek is fast approaching his 30th year in Arboriculture. He began when he saw a tree gang working on some large London planes in 1988 and after a trial period of one week knew this is what he wanted to do. Thankfully for us, he got offered a job on the last day of his trial period!! Since then, Derek has done many qualifications in various aspects of the industry.

Derek has a passion for preserving our country’s existing trees and natural environment as well as promoting industry best practice for the management of trees. He has recently moved from training and assessing young arborists and firmly believes in the Gristwood and Toms ethos of actively promoting safe practices.

Derek likes motorcycling, paragliding and painting. His dream is to either fly a lap of Laguna Seca or to climb a giant Sequoia in Oregon.

Name:

WILL ROLPH

Position:

Tree Surveyor


Will started climbing like most kids as a child. When he was 16, he started climbing professionally for his brothers company. Whilst at university, he was also self-employed as a climber and consultant. He has been in the industry for 6 years.

He loves being and working outside and the most important thing to him is appreciating the trees for what they are but also applying the most sustainable management techniques when necessary to achieve amenity and safety.

Will has a particular interest in tree/fungi relationships and tree failures/biomechanics. He is hoping in the not to distant future to do MsC in Mycological Studies in collaboration with Kew Gardens.

Will says that his hobby is work. He honestly loves what he does and working with trees is satisfying. In his spare time he climbs recreationally which gives him a chance to catch up with his college mates. Surfing is another passion although he doesn’t get too much of an opportunity to do it. He loves to go on holiday and tries to seize the chance to get away somewhere hot!
