Testimonials

  • "I was introduced to Derek Welsh and his team several decades ago. I have been very impressed not only with the excellent service the team at Authentic Tree care provide but also the knowledge of the various species of trees and suitability for various growing conditions is excellent. I have used their services at my home , my office building along with my cottage island in Georgian Bay. I have always been very pleased and impressed with the service I have had."

    Janice Vincent

  • "For over 27 years, Derek and his team at Authentic Tree Care have been taking exceptional care of the trees on our properties, including our tree-heavy ravine. Their expertise truly proved its worth during a past ice storm—while many properties suffered severe damage, our trees remained intact. We credit this to the meticulous pruning and care that Derek and his team have provided throughout our 25 years of owning this property... I’ve recommended Authentic Tree Care to many friends, and they continue to use and appreciate Derek’s outstanding service. I wouldn’t trust my trees to anyone else."

    Yvonne Fleck

  • "Derek takes care of all the tree work on my property, and living on a ravine means there's always plenty to do! Whenever a tree limb falls or I have an emergency, Derek responds immediately, ready to help. His team is skilled, efficient, and professional. He also does an exceptional job trimming all of my hedges, keeping everything tidy and beautiful. Derek himself is neat, personable, polite, and consistently punctual - truly a pleasure to work with. I honestly couldn't manage without him!"

    Gladys & Lloyd Fogler

  • "Derek has consulted/worked/educated me and my clients for two decades. I realized from the beginning that his passion for trees matched my own. We spent years teaching each other all the things we learned actively growing and observing trees: how to plant properly; how to adapt to all the new information and the changes in the environment that affect our amazing canopy... Aesthetic and environmentally-conscious arborist is a rare thing and well practised by Authentic Tree Care. You can trust them with your most valuable garden asset: your trees."

    Marjorie Harris

  • "I cant's say enough good things about the work our arborist has done for my tress. His knowledge and expertise are truly impressive-he's brought a few trees back from brink, carefully fertilized and trimmed others, and left everything looking healthy and vibrant. He's always available when needed, incredibly professional, and just a genuinely nice guy to work with. It's rare to find someone who combine skill, dedication, and kindness so effortlessly. I'm grateful for the care he puts into every visit-my tress have never looked better!"

    Dr Nar Singh

  • "Derek is an amazing arborist. He keeps our trees under control while looking as if no one has touched them. The magic touch! Or is it the magic cut."

    John Ralston Saul

  • "We've had Derek and his team looking after our trees for many years and each season he plans and executes the work to manage, prune and cut to highlight the best across the property. After years now their efforts have improved the value and beauty of our property beyond the cost of the work itself."

    Brad Baker

“Derek has looked after my trees and gardens for over 20 years and I would recommend him to anyone. He is honest and direct and knows exactly what needs to be done.”
