Ive been going to Mark Garrison salon for several years now.  The best service of the salon for me is by colorist Sam!  He does an awesome job on my hair.  When I first met him, I had blonde highlights in y hair and I was very unhappy.  I was becoming a blonde!  My natural color was in the reddish family but had gone more toward mousy brown as I got a little older.  he immediatley said he saw me as a redhead, not a blonde!  Now my hair is this gorgeous shade of red (not screaming red or eggplant) and everyone thinks it is my natural color.  People stop me and ask me if its natural and then want to know where I color my hair.  Sam has such a great eye for color and also a very nice personality as well.  Rosie cuts my hair and does a fine job as well., but Sam is definitely my guy.  I would never consider coloring my hair elsewhere.
Pros:  Color Department, friendly staff, haircuts, 
Cons:  prices increase very frequently, ambience a little cold but maybe thats the look.
