Miguel did my piece and was very attentive to my low pain tolerance and sensitivity. He let me know that he would go slow to see how i felt since it's my first tattoo. I definitely recommend him if anyone wants to get a tattoo. read more

Awesome experience! Specifically chose Jerry as my artist after seeing his work on their website, and couldn't be happier with my decision. From the moment I arrived, the space felt welcoming and comfortable. Jerry greeted me right on time and immediately set the tone with patience, kindness, and professionalism. He's a true artist, not only technically skilled but also incredibly thoughtful. He took the time to make sure the design was exactly right, and we settled on something I love. Throughout the process, he was attentive and reassuring, checking in and making sure I felt comfortable every step of the way. Came in to cover a terrible tattoo from my childhood, and Jerry completely transformed it into something meaningful and beautiful! read more

Where do I even start?! I've been rocking with Adrian since 2019. But I've actually known about Adrian and his tattoo work since 2016! I served in the Marine Corps and while coming out of the showers I saw a fellow Marine with a beautifully done Jesus piece, I asked who did his art, and lo and behold it was Adrian! Now as of October 11th, 2025 we have finally completed my arm sleeve! I'm nothing, but thankful to Adrian! Throughout the years he's been patient, kind, fun to be around, and truly dedicated and masterful when it comes to his art! Before this location was fully established Adrian actually did my first tattoo in an AirBnb! He came up from SoCal, and since I was from the Bay Area and he was tattooing on his visit, I jumped at the opportunity and never looked back. Since 2019, I've come down from San Francisco where I'm from and have gotten a tattoo every year, 2020, 2021 out here in SoCal with Adrian. But I stopped for a few years due to the pandemic and low funds. But it's 2025 and the hiatus is gone and the arm sleeve is complete! I got nothing, but high praise for Adrian, his art, his dedication to his craft speaks for itself. And in my opinion, he's worth every single penny! A tattoo will be on you for a life time, don't be cheap with yourself! I really can't recommend him enough, it takes a lot of trust to let someone put permanent ink on you for a lifetime, but when it comes to Adrian that decision comes easy. Every tattoo I've gotten from him has been a banger! But it's much easier to show y'all than tell y'all! 2019: Lion 2020: Hooded Angel slaying Satan 2021: Roses and Thorns 2025: Satan as Leviathan and a simple man facing him. My 2020 piece is a metaphor indicating that even you can conquer your own demons. (Hence why the angel has a hood, so you can picture yourself under it). My 2025 piece is a callback to my 2020 piece, and reverse dynamic where Satan is much more powerful than the man facing him, but that shouldn't stop you from facing your demons! This has been a long read, but hopefully it helps y'all make a decision if Grey Theory Studio and Adrian is worth it! read more

After alot of research on alot of shops in the area. I felt like grey theory had the vibes I was after. All the artists are so talented. I loved how everyone in the shop had input on the placement on the pieces before they were pasted on you. The shop environment was just so professional and extremely clean. Daniel is just an outstanding artist. He exceded my expectations on my hand piece. I expressed a few ideas, and let Daniel run with it. He did So darn good I had to make another appointment to get my head tattooed in a couple weeks. read more

Vide!! Chill, clean. Everyone in there is cool. Entry is in the back and in the cut. I think that helps with the cool vibe. All artist seems the real deal. I had a simple tatt (compared to everyone else.) I walked in, and they found a way to slip me in. Youngblood, Jerry hooked me up. Took time to make sure the print was right, and it then took the time to make sure it was laying on the arm correctly. Will be back. read more

So 1st of all...... they all have so much patients. I was all over the place about appointment dates and time and just exactly what I wanted. Thank you. The studio is clean, calm and inviting.

Just wanted to give this shop a nice review. All of the artists were tattooing while I was getting my piece done and it was a super chill vibe in the space. There is a LOT of room in the shop and it has a great wood work and brick decor that gives it a nice cool feel. A very special shout out to Daniel who tattooed me. Super chill guy with a great soft spoken nice demeanor. He does great work and I'm super happy with the chest piece that he did on me. I have been getting tattooed for many years and I can't say anything but good about Daniel so check his work out on IG and give him a shot if you're looking for some great black and grey work read more

Amazing Experience! My friend and I came in to get matching tattoos that are about 2 inches, line work with some shading. Our artist was Lupe and she was incredibly talented and great to talk to. She made suggestions and really worked with us to get the placement and look exactly how we wanted. The space itself is very clean and large. Parking was right outside and pasadena is a lovely spot. Everyone was very professional and made the experience seamless. Even when I sent in my appointment request at 9pm a few weeks ago, I got an email back within 30 min! I was totally not expecting to hear back that night but they got me an appointment fast. Highly recommend Lupe and grey theory studio! read more

Yo my boy Steven got me right. Finished my sleeve, two days work. (7-8 hour sessions) He's worth the money. Unlike every other artist , my guy actually cares about his clients. That's right, you're not just a customer, you're his client. If you're trying to get ink, go see my guy. He will get you right. read more

I hardly ever write bad reviews, but I had a terrible experience, and so did the people in the waiting area. I made an appointment and deposit 4 months in advance. When I showed up for my appointment 15 minutes early my artist (Adrian) was not there yet. I waited in the lobby for an hour and still nothing. I asked the person working there if there was an issue and they replied, "I'm not sure, but he is probably just running late". I can understand 15 minutes late but an hour and no update? Worker said, "I'll give him a call" . The worker proceeded to do absolutely nothing and just chilling on the phone. I got up and just left. I lost 80 minutes of my time and $150. This place needs to be investigated because there was another person waiting just as long as myself and looks like someone in the comments had a similar problem. I can only imagine those who didn't care and didn't leave a review. read more

I got my first tattoo here! They were super friendly, they executed the design I had in mind just the way I wanted them to - I was a bit clueless since it was my first tattoo but they guided my really well! Thanks so much to my artist! read more
