About Joseph McNeil

With a strong general interest in science, biomechanics and engineering, and as it relates to trees as large biological structures, Joe founded Lion Tree Service in 1971. Within a few years he expanded his business to include consulting, and later added landscaping, as Lion Landscape and Tree Service. As an owner-operator of a full service tree care business he has been involved with education, training and certification through the local, regional and international arboriculture community. He attends numerous seminars and conferences annually, and has taught arboriculture at the community college level.

Joe has strong personal organizational skills. His attention to detail combined with a firm understanding of the physiology and structure of trees and long experience with public perceptions of trees factor into his ability to assist individuals, property managers, and public agencies to make decisions about their trees. Since converting his business exclusively to consulting in 1995 Joe has continued to hone his practice through continuing education seminars, workshops and conferences. During this period he has become an established and respected consulting arborist.

Joe’s philosophy in business mirrors that in his life. He believes in a studied comprehensive approach to his work, staying intellectually current, personally and within industry practice and standards, with respect for the environment, all in a practical and ethical manner.
