Both of my neighbors have very large oak trees. One had large limbs growing over, around & into my mature mango tree & on the other side, that oak reached all the way on to my roof & gutter. Neither trimming was a highly complex job, but both trees posed different problems that required thought, experience & skill. DIETRICH TREE SERVICE did an onsite estimate & quoted a reasonable price. I scheduled a date for the job & said it was contingent on seeing his insurance. On 12/11/15, Dietrich arrived to do the job, showed me his insurance & got to work. My mango tree did not loose a branch, my roof & gutter did not have a scratch & they removed everything that they cut down. Both of my neighbors were OK with the condition of their trees & I was very pleased with the job they did. He did what he said he would do for the price that he quoted. I will call DIETRICH TREE SERVICE anytime I need tree service.
