Our Story
Over 30 Years of Expert Tree Care in Chicago
A-1 Tree Services was founded in 1998 by Sahip Zengilani with a simple promise: give Chicago homeowners honest advice and expert tree care at a fair price. More than three decades later, that promise still guides everything we do.
Tree removal requires an expert hand. Our tree technicians handle every job — from a single overhanging limb to full lot clearing — with the right equipment, the right safety planning and genuine respect for your property. We serve both residential and commercial customers across the Chicagoland area.
Not sure how to handle your tree problem? We'll give you the information you need to make the right decision, whether it's tree trimming, felling and removal, lot clearing or stump grinding. Every job starts with a free estimate, and after the work is done we'll even leave the wood chips for you if you like.
