Keeping it brief: Excellent shop, extremely welcoming people, clean as can be, stylish, comfortable vibe, good music, and excellent artists from what I've seen (worked with Rae my first time but all of the portfolios were quite amazing).
The long of it: John was the reason I took the time to look in to the shop. He answered all of my tedious questions (I am used to Southern California shops which can be either great or fairly sketchy but in both cases, most seem to show very little customer service). Seriously, the dude (John) responds in no time at all, he's courteous, and--where many shops fail--actually sends back an informed, customer-oriented correspondence. Well done.
Karen is equally friendly, talented in the work I've seen, and gave me an honest opinion on my piece when I was going back and forth on sizing, etc. to leave enough space to work with later; balanced chick and as I understand she does some charitable work for breast cancer victims.
Finally, Rae did a killer job on detail even when I decided to compromise on the size a bit. She's kickass with a great deal of talent, a sense of humor, and makes you feel right at home in the shop.
5 stars, no doubt.
Note: This was not my first tattoo but it was my first piece in Colorado and at this shop. I plan to finish additions to the piece here and my wife will more than likely be scheduling two pieces with Rae soon!
