Office and Operations Manager
Levecke Mas is proud to join Out on a Limb Tree Co, and support such an awesome crew, and she is not just saying that because she happens to be married to Kathy. She brings over fifteen years experience in front office management to the daily operations of the company, enjoys working with spreadsheets, loves keeping track of details and talking to people.
When she’s not working in the office or doing the crossword puzzle with Kathy, she enjoys walking, hiking, riding her bike and traveling as much as possible.

He is happy to now be working with Out on a Limb and learning to care for the native trees in the NW. Winter or summer, when not at work Dilphe will most likely be found at the water’s edge, fishing and enjoying nature.
George White is a Seattle local who has been working in tree care since 2016.

Harley is half Australian cattle dog (“blue heeler”) and half German shorthair pointer, and joined the team at the ripe old age of 8 wks in February 2017. She is very excited to pull her own weight as a member of the team, but we suspect it won’t happen at least until she gets her adult teeth.
