Proudly Serving Philadelphia Since 2014

My wife and I just got our second tats from John Howie, and I can’t express how impressed I am with this shop. Way relaxed and cool vibe, professional to the core and killer, killer artists. I got a Jules Feiffer illustration on my forearm, and the rendering was spot on – especially impressive given the non-standard tat image. Will be back, and back, and back.

Friendly, professional, committed to clients, and DAMN GOOD ARTISTS. My sister and brother-in-law have been raving about this shop for years; so much so that I made an appointment for when I was visiting (even with my own artist at home.) BEST DECISION EVER. SO happy. Now I know what all the fuss is about.

I just got my second tattoo from John Howie and he is the absolute best. His shop has a great atmosphere, and everything was so sterile and clean. He himself is a great artist to work with and I will definitely be returning to Frequency.

Came with a rough sketch and John was able to refine it for me. Great guy to chat with, even better tattoo artist. Really happy with the work he did; will recommend to my friends in the area. Definitely a solid tattoo parlor.
