About Andrew
Andrew leads sales and estimates business development for Tree Wise Men. Before entering arboriculture, he built his career in radio advertising — work that gave him strong communication and client-relationship skills. A love for the outdoors drew him to tree care, and ISA certification turned that passion into expertise.
A typical workday for Andrew is going to different sites, meeting with homeowners and business owners, and going over concerns they might have with the trees on their property — and how Tree Wise Men can help. Decisions about whether to remove, cable, or trim a tree involve a lot of factors. Risk assessment is the biggest part: what level of risk does the tree pose, what level is the homeowner comfortable with, what's the tree's location relative to structures and people?
When clients request topping a tree to reduce its height, Andrew has the harder conversation: as arborists, Tree Wise Men doesn't top trees. Topping opens trees to insect and disease issues and sets them up to fail over time. The honest assessment — even when it's not what the customer first wanted to hear — is what builds the long-term relationships that have driven Tree Wise Men's 700+ five-star review base.
