Its going on two years since I have been going to this salon and I am a client of Katherine. She is AMAZING. I am still not a huge fan of their "concept" that the color formula is in the books and any of their colorist/stylists can take care of you. I prefer to have one person consistently do my cut and color (I book at the same time, the moment I check out). That is just me, some other clients seem to be ok with this. Make sure to speak up when rebooking but overall, I still enjoy going.
