Martin Macauley

CEO, ISA Certified Arborist #PN-5768-A (click to verify) ISA Certified Tree Risk Assessor B.S., Mechanical Engineering (UW '85) Master's, Business Administration (Seattle U '90)

Martin comes from a long line of tree experts. With a grandfather who was an Oregon logger in the 1930s and 40s, and a father who founded a successful logging company in the 1960s and 70s, Martin grew up with a love of trees and a keen knowledge of balancing customer needs with natural aesthetics. After earning a mechanical engineering degree (UW '85) and an MBA (Seattle U '90), Martin found life as a Boeing engineer too stuffy (he calls it the "cubicle lifestyle"). He returned to the outdoors as a tree man, soon earning his arborist certificate from the International Society of Arboriculture and founding Blooma Tree Experts LLC. He married Judy in 2007, and soon afterward, enticed her to join Blooma.

Josiah Macauley

Co-owner, ISA Certified Arborist #PN-7246-A ISA Certified Tree Risk Assessor B.A., Business (UW 2010)

Josiah learned the ropes from his father throughout high school and college, working on the Blooma crew every summer and holiday break. After earning his business degree at the University of Washington, Josiah worked several places, ending up as an arborist for the city of Seattle Department of Transportation. In 2016, he fulfilled his father's goal and joined the family firm as a partner. Josiah is married to his lovely wife, Lauryn.

Ben Kirsop

ISA Certified Arborist Ben Kirsop is our crew lead, a competent young man who has boundless sources of energy (oh, to be 24 again!). He is a skilled climber who is very knowledgeable about trees. In fact, he has attended the past two ISA conferences (one in Boise, ID and the other in Lynnwood, WA) in order to continue his education. In his off time, he goes dirt bike riding, snowboarding, snowmobiling, jet skiing . . . anything that's fast and fun.

Drew Cheney

Arborist Drew Cheney worked full-time for Blooma for several years before going off and doing his own thing for awhile. Now he is back part-time, bringing us his years of expertise and enthusiasm. Like most climbers, Drew loves adventure and adrenaline-causing activities, especially white water rafting in the summer and downhill skiing in the winter. He has recently taken up dirt bike riding, too, and can often be found on the trails with Ben.

Zane May

Zane May is our arborist-in-training. As an apprentice climber, he is learning the ropes from our experienced pros. He has also completed three courses in tree pruning taught by Plant Amnesty and the UW Center for Horticulture. In his off time, he often goes dirt bike riding and snowboarding with Ben.

Bill Andrews

Groundsman Bill Andrews is our official Safety Guru, acting like a father to younger set, making sure they are safe. He also can drag brush better than anyone else, working constantly, like the Energizer Bunny. In his spare time, he enjoys fishing and spending time with his wife and grown daughters.

Rob McDougall-Treacy


Groundsman Rob not only works hard every day, but he helps make the time pass enjoyably with his quick wit and charm. He and Bill, in particular, enjoy exchanging banter as they work to keep the job site clean and safe.

Judy Macauley

Office Manager Judy Macauley is wife to co-owner Martin and stepmom to co-owner Josiah. She has helped Blooma since its inception in 2005, joining the team full-time in 2014. When she isn't talking to customers, scheduling bids, or straightening out the books, Judy enjoys creating fused glass art and spending time with her three beautiful grandchildren.

Marie Abaya

Office Assistant Marie Abaya works part-time for Blooma, answering calls, scheduling bids, coordinating firewood pickup, and attending to all the details that makes our office efficient. She is a newlywed (sweet!) who spends a lot of her free time throwing pottery, attending art shows, and traveling.
Blooma has always been a family business. Martin employed his two sons, Josiah and Michael, throughout their high school and college years when they were available. Josiah is now his business partner; Michael graduated with a B.S. in electrical engineering from UW Seattle and is an engineer at a firm in Lynnwood, WA. The legacy is continuing as we teach a third generation the ropes: Jin Eyon, Martin's grandson, is joining the Blooma crew during the summer of 2018, getting his first taste of the world of urban forestry Learn more about our Seattle tree and arborist services »
