Meet Our Certified Arborist

Omar Dennaoui

An arborist is someone who specialises in the care and maintenance of trees but it's not a word you often hear. Arborists are commonly referred to as tree loppers. Omar is a certified arborist who finished his formal training in Arboriculture at Holmesglen Institute (Waverley campus). As the owner/operator of Big O's Tree Services, he prioritises care in every job. What began as a tree lopping hobby for him has evolved into a business serving both residential and commercial clients across metropolitan Melbourne.

Omar is also the proud owner of Big O's Slashing Services, offering acreage lawn mowing services for larger properties (one acre or more) across the southeastern metropolitan areas of Victoria. You can find more information about slashing, acreage lawn mowing at: https://bigoslashing.com.au/
