Deb K.


After being away from Oregon for more years than she cares to admit, Deb returned with her family and landed in the Willamette Valley in the summer of 2016. She will tell you that bookkeeping is tailor made for her because she is a natural investigator, and doesn’t give up on new challenges. Her drive for order, balance, consistency, and completed check-off lists makes her happy on a daily basis. In her spare time, she is a maker; crafting, sewing, painting, building, landscaping, gardening, decorating, and coming up with even more ideas to be creative, but she always makes time to enjoy Oregon’s beautiful outdoors!
