This is my second time coming to this shop and all the artist are super kind and attentive. I got my tattoo done by Mariel and she is amazing. This is my second tattoo done by her and I will keep coming back to her. The shop is very clean. The only downside is parking, but I feel that’s common in the city just make sure to prepare ahead in case you can’t find parking near the shop.

Mariel is a true artist. Not only are her tattoos absolutely beautiful and incredibly detailed, but she works SUPER fast with a light hand. I am on my second piece (I have 5 total tattoos)with her and I truly would not go to another artist. The quality and staying power of her work is incredibly high and worth every penny (and the pain!). As a bonus, the studio is super welcoming, warm, and calming. Mariel is an absolute gem and a privilege to work with h

Mariel Bayona was my artist and she was so kind and patient in helping me choose a placement I was going to love. She always made sure I was comfortable and in general was just incredibly warm & welcoming. If you’re looking for a place to feel safe and heard for your tattoo experience this is it. I was there for about 7 hours total, 5 hours of tattooing and had a wonderful experience getting my first large scale tattoo with her & couldn’t be more thankful for it. I honestly can’t wait to go back in the future! Thanks so much Mariel!

Mariel and Sai are both very talented artists and their studio is one of the most welcoming and relaxing spaces I’ve ever been tattooed in. My session was with Mariel, and she really took her time to create a comfortable tattoo experience for me. I absolutely LOVE my tattoo from Mariel, and I highly recommend working with her!
