I called Ray Williamson to remove 4 large (30 ft ) oak trees that were dangerously curving over onto my roof. I was looking for pro and not someone with ladder chain saw. He is certified Arborist.He was on time and brought a crew of 3 others. They diligently methodically removed the trees without endangering my roof.He makes climbing massive trees with chain saw look like child play.He went well beyond what i called him for and spent the entire day grooming trees all around my house and made sure i was completely 100% satisfied. Awesome Tree Service in Austin/ Round Rock area.thanks Ray,Omer
