About the Founders

In 1960, Harold Van Dyke founded Richmond Hill Tree Service and Forestry Company Ltd. with a goal to provide professional care to trees and lawns with a quality-driven focus, to have certified and knowledgeable staff with great respect for the environment and the customer. The company is now under the care of Harold Van Dyke’s son, Larry,  who always strives to continue the quality of service that was offered at Richmond Hill Tree Service and Forestry Company Ltd. 


In 2004, we made the big decision to specialize solely in tree care, to focus all our attention on the Acers and the great Oaks of our time. We focused on giving the trees the nutrients and maintenance they require to last for the next generation to enjoy and appreciate. From this step, the company’s name was edited to reflect the change to what it is today, Van Dyke’s Tree Care. Today we make to you, the customer, the same promise that this company was founded on - to give you the best customer service for your dollar and make recommendations for you to keep your plants healthy.
