Fiona Curtis

I’m Fi, originally from Cornwall in the UK. After settling for 5 years in the interior of BC, I made the move out to the ocean and Vancouver island. It felt like a natural move as the ocean reminds me of home but I still get to enjoy adventures into the mountains. I originally started training as an arborist in the UK and plan to complete out here in Canada. I love arbory as it combines nature and the outdoors with technical and fitness aspects. I can’t wait to continue to learn and explore all the natural wonders that Canada has to offer! So many things to do and so little time!

Hi there, I’m Read Guthrie, and I’ve been working in the arb industry for just over three years now. What draws me to arboriculture is the way in which it incorporates both a physical and mental discipline with a scientific study of tree health. Having grown up on the island I have a great appreciation for our native forests and the diversity found in our microclimates. The Comox Valley has a little bit of all the island has to offer and that, to me, makes it the perfect environment to live and work as an arborist. Most weekends I can be found outside trail running, snowboarding, skateboarding or climbing. Working at Grow means being part of a team and part of a family, and with our shared experience I expand my knowledge each day.

Hey there, I'm Steel. I grew up on unceded Algonquin Anishinaabe territory, otherwise known as the Outawais region of Québec. I am very grateful to now live here on the traditional and unceded territory of the K'ómox First Nation. I've worked in the tree care industry on and off for several years. I am stoked to now be in training as a climbing apprentice! My work background is varied with experience as a wildland firefighter, park operator, tree planter, cook, programme coordinator and backcountry guide. I studied environmental science and Indigenous studies in school. I maintain a keen interest in ecology, natural and cultural history, and plant medicine. When not at work, you may find me out paddling, cycling, hiking, rollerskating or lazing in my hammock with a book. Je parle Français y hablo Español también - I look forward to connecting next time you’re on site with us!

ISA Certified Arborist® ON-2554A

First Aid

Hello! I’m Madison Tosswill. I’ve been in the arboriculture industry for 5 years. As a climber, I love the physical and outdoors aspects of tree care. I enjoy learning about trees and all the complex functions of natural environments. I started working with trees in Ontario where I went to school for Arboriculture and Urban Forestry and gained experience with a few companies. Living in the valley is wonderful and allows me to enjoy many outdoor activities like dirt biking, cycling, rock climbing and exploring new places on my spare time. I’m stoked to be a part of the Grow team and look forward to this new adventure.


David Wallbridge

Hi, I'm Dave. I grew up in the New Forest, England, where I always took great joy from the trees that surrounded me. Whether at work or at play, the outdoors has always been a huge part of my life, and it seems inevitable that I would one day find myself working in arboriculture. I've had the privilege to have been involved in tree care in the United Kingdom, New Zealand, and now here on Vancouver Island, where I've quickly fallen in love with the beautiful natural environments and great outdoor spaces. It's a pleasure to have found a role within the team at Grow, who share my compassion for trees, and recognise the value they add to all of our outdoor spaces.
