The Company 

I.V. Tree Care was started in 1999 by Certified Arborist Olen Sharron after retiring from the USDA. Olen was dedicated to saving Hemlock trees from the deadly Hemlock Woolly Adelgid (HWA), an imported insect that has killed millions of trees. Unfortunately, Olen passed away in August 2007 after a valiant battle with cancer. In February 2008, Virginia Tech graduate (MS Horticulture) and ISA Certified Arborist Jim May took over the business and has continued to save thousands of Hemlocks in Southwest Virginia. Jim has even expanded the business to cover many more insect and disease problems, including the Emerald Ash Borer (EAB), Scale Insects, Lacebugs, Aphids, Fall Webworm, and other biting and sucking insects. Diseases controlled by I.V. Tree Care include Bacterial Leaf Scorch (BLS), Anthracnose, Dutch Elm Disease (DED), and many more. Jim constantly continues to learn about new insect and disease problems through seminars and webinars. Jim maintains his CEUs to keep up with his certifications as an ISA Certified Arborist, Certified Tree Risk Assessor, and Virginia Certified Horticulturist. He does all that while being a Virginia Certified Pesticide Applicator, a different full-time job of Jim.
