Certified Arborists Serving Simi Valley & Los Angeles

Natural Wonders Trees has been the go-to tree care company for homeowners, HOAs, and commercial properties throughout Southern California since 2007. Our ISA Certified Arborists — holding credentials through the International Society of Arboriculture — bring science-based tree care to every job, whether that's a single backyard oak in Simi Valley or a multi-acre commercial property in Thousand Oaks. We're not just tree cutters; we're trained arboricultural professionals who understand tree biology, structural mechanics, disease pathology, and the specific climate conditions that affect trees across Ventura and Los Angeles counties.

Southern California presents a unique set of challenges for tree health that you won't find in other parts of the country. The combination of prolonged drought stress, high-wind events like the Santa Ana winds, sudden soil saturation from infrequent but intense rain, and a pest and disease landscape that includes shot hole borers, polyphagous shot hole borers, and sudden oak death means trees here need informed, attentive care. Our arborists are trained specifically in these regional threats and know what to look for before a minor problem becomes a hazardous one. We diagnose issues that other companies miss because we treat tree care as a profession, not just a trade.

Our service area covers 27 cities across two counties — from Simi Valley and Moorpark in the west to Encino, Sherman Oaks, and Northridge in the San Fernando Valley, and north through Camarillo, Ventura, and Oxnard to the coast. We also serve the hillside and canyon communities that many tree companies avoid: Pacific Palisades, Malibu, Hidden Hills, Calabasas, Agoura Hills, and the rural-residential properties around the Santa Monica Mountains. These terrain-challenging locations are actually where our rope and saddle climbing skills — developed over two decades of work in steep, difficult-access sites — make the biggest difference. We don't turn down jobs because they're complicated.

Credentials matter in tree care, and ours are verifiable. Natural Wonders Trees holds CSLB License #900295 with D49 (Tree Service) and C61 (Limited Specialty) classifications, both issued by the California Contractors State License Board. Our lead arborist Juan Bautista holds ISA Certified Arborist credential #WE-12613A and CTSP (Certified Tree Safety Professional) #022097. We carry comprehensive general liability insurance and full workers' compensation coverage on every job. When you hire an unlicensed tree service to save money, you risk being personally liable for injuries that occur on your property — a risk that consistently costs homeowners far more than the service itself. Our licensing and insurance protects you, not just us.

Free estimates are a standard part of how we work, not an upsell technique. Our arborists come to your property, walk the site, assess the trees in question, answer your questions honestly, and provide a written proposal with clear scope and pricing — no obligation. If we think a tree can be saved with pruning rather than removal, we'll tell you. If a tree you're worried about is actually in excellent health, we'll tell you that too. We've built our reputation on honest assessments, not on selling work that doesn't need to be done. Call (818) 717-8787 or visit our website to request your free estimate today.
