Our History

Jeff Grennan, the owner of Treeline Tree Service, grew up in San Diego and developed a passion for trees and the outdoors. He learned the business from his father, Al Grennan, a local botany professor and expert in native plants. Jeff started working in the tree care industry in his 20s, learning from well-known local arborist Michael Ball. After years of honing his skills and building a reputation for quality work, Jeff founded Treeline Tree Service nearly two decades ago. Today, we continue to serve the same community with the same level of dedication and expertise.
