Public works director Patrick Ryan possesses more than a decade of experience managing maintenance and operations for municipalities, including the Village of Homewood, just outside of Chicago. While serving as the assistant director for the Village of Homewood, Patrick Ryan leveraged his background as a certified arborist to ensure that the town’s trees met safety and compliance standards.
Certified arborists are tree-care professionals who have been recognized by the International Society of Arboriculture (ISA). ISA credential holders must abide by an industry code of conduct and demonstrate a high level of knowledge on tree health, environmental sustainability, and landscape architecture.
Prior to taking the ISA certified arborist exam, applicants must have at least three years of direct experience in horticulture or arboriculture. This includes work experience in a garden center, landscape company, or government agency. Candidates must also hold a degree in a related field.
The ISA exam covers 10 subject areas, such as safety procedures, soil management, and tree identification. After passing the exam, certified arborists must enroll in continuing education courses to maintain their status.
