If you're looking for a Deva cut in Portland, I whole-heartedly recommend going to Sarah at Kiss Kiss. Besides having a lot of experience doing Deva cuts, she has worked with Lorraine Massey a good deal.
When Sarah cut my hair, she told me I'd probably want to see her again in six months to a year–and eleven months later, I just made my next appointment with her! I've never had a cut that could last more than four or five months and still look this good. Sarah was really good at listening to my concerns and making a cut that would perform as I wanted it to when I braid my hair, on my bike, etc. Kiss Kiss is in the ground floor of a vintage home, and has an amiable atmosphere. They sell all the Deva products except I think the hair dryer.
