Meet Jeff Grennan, Owner of Treeline Tree Service

Jeff grew up in San Diego surfing and fishing our local waters and learning about native plants from his father, Al Grennan. Al was a local botany professor and an expert in native plants. Jeff spent much of his youth helping Al collect local plant species in the San Diego backcountry.

Jeff started as a groundsman at Treescape Tree Service in his 20s, where he learned the finer points of tree care from Michael Ball, a well-known local arborist. Jeff has been a dedicated tree guy ever since. After years of hard work, Jeff became a foreman and an expert climber. A little over 13 years ago, Jeff earned his contractor’s license and set out on his own to start Treeline Tree Service.

Today, Jeff is known in the local community for his knowledge, his friendly, down-to-earth manner, his artistic eye and his dedication to customer satisfaction.

Many of Jeff’s original customers still call Jeff for their tree care needs, and Jeff still meets every customer himself. Jeff employs a small, highly skilled crew so that he can guarantee outstanding results at a reasonable price. Jeff prides himself on the quality of their work and the skills and knowledge they bring to every job.
