One of the trees in my front yard has maple wilt, I really do not want to cut the tree down, is there a cure or anything I can do to fix the tree? Also could you give me name(s) of a certified arborist that i can contact?

It is difficult to say for sure if your maple tree has dieback that is a result of maple wilt caused by Verticillium, or some other plant disease fungus, or merely environmental stress. If you trim off a branch, you should see dark discoloration in the water conducting or vascular tissue if it is Verticillium. In our area, there is a lot of dieback to other opportunistic fungi such as Botryosphaeria which gets into branches through breakage and wounds. Botryosphaeria has a very wide host range, and can also cause a leaf spot, but it over-winters in the twigs and bud scars.
I would recommend calling a certified arborist, who will evaluate the tree and prune it to save the tree. I also suggest reducing stress on the tree by watering during extended periods of drought in the summer, mulching, and avoiding injury by exposure to lawn chemicals, environmental stress and wind.
I do not usually suggest names of individual companies for tree care, but recommend that you check online or in ads for that ISA (International Society of Arboriculture) logo.
