When he’s not doing tree work or training tree workers, he loves hanging out with his three amazing daughters and getting out into the mountains to hike, bike, and climb with them.
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.
Karsten Foerster is an ISA Certified Arborist (PN-7911A) and our crew lead, and has been working in tree care since 2013. Prior to tree climbing, Karsten served a five year enlistment in the United States Marine Corps as a helicopter structural mechanic. Karsten now enjoys using his attention to detail and strong work ethic towards caring for customers’ trees. In his free time he enjoys fly fishing and backpacking.
Martin Selasco is an ISA Certified Arborist and a TRAQ qualified tree risk assessor, and has been working in tree care since 2011. After graduating Pitzer College with a BA in Environmental Studies, he spent a summer conducting habitat surveys in the old-growth Doug fir forests of southern Oregon and fell in love with tree climbing. Upon returning to Seattle, he decided to make a career out of climbing and maintaining trees. In his free time he enjoys making music, hiking, and skateboarding.
Kyle Strohl is an ISA certified Arborist (PN-8451A ) who came from the hardwood forests of Southeastern Ohio to work in the trees of the Pacific Northwest. He has a BA in Plant Biology from Ohio University and considers himself an avid tree conservationist. In his free time he enjoys rock climbing, hiking, biking, skiing, and anything else that gets him into the mountains.
Nate Larsen found Out On A Limb a few months after relocating to Seattle from the Florida panhandle. His previous experience as a theatrical rigger cultivated his love for climbing and work at height but the need to reconnect with nature led him to begin a search for a job that would let him get to work outside every day. An avid knot enthusiast, Nate can often be found working on splices in his spare time and tying rope around various objects and calling it art. On days off when he is all out of cordage, Nate enjoys hiking, playing music, and road trips.
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.
