Luigi B.

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!

I have being here a couple of times & if im being honest I keep coming back for more ink. Adrian has been a great tattoo artist over all. Keep in mind that i have to drive 2 hours & a half to get to his shop but it doesn't matter because every trip has been so worth it. Him & his team are great! They are very responsive and communicate well. Their shop is always clean & the music playlist is always a plus. If you're thinking of booking with him, I HIGHLY RECOMMEND you to do it. You're not going to regret it i can promise you!!! ill leave you proof of adrian's work, by the way This one i get lots of complements

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.

Came across grey theory at the Golden State tattoo expo in Pasadena, specifically with Daniel. Daniel's work speaks for itself, he's very talented. I reached out to set up anappointment and he came through. The studio itself is very clean and an overall great environment. I will definitely be back in the future. Check them out on IG: greytheorystudio Daniel's IG: elseloso_205

Just got a tattoo by Adrian Lazaro he did great work will definitely be going back to him, his shop was a good atmosphere would definitely recommend getting work done at this location

Been working with Adrain for some time now. Full sleeve progress coming along. If you looking for quality work and real custom pieces consider grey theory studio! Full of experience and pays attention to detail. Adrian gives all his attention to his customers and he has a strong portfolio with lots of experience in the! 10 hr progress run last night, took breaks as needed and never rushed the process. Best in the game

I had a wonderful experience at Grey Theory Studio. The staff were polite and attentive, making me feel valued throughout my visit. The establishment was clean and well maintained, which contributed to a pleasant atmosphere. their music playlist was on point! I truly appreciate their friendly demeanor and understanding nature. The quality of work provided was excellent reflecting their commitment customer satisfaction. I highly recommend Adrian for anyone who's wanting to get work done. Adrian is creative, provides good guidance and makes you feel comfortable throughout the process.

Friday (Saturday) the 13th flash. Great selection, awesome artists, clean studio, easy to communicate with. Will definitely come back. I wasn't able to go in the 13th but they had the sale all weekend so that was awesome. I love my new addition. Also, parking was great, places to eat, and open late. Got exactly what I wanted

Ismael G.

Easily my best experience getting tattooed. I came in for Friday the 13th flash tattoos. These two came out for a total of $200! Besides the great price, the shop is clean, Jerry is patient, and his experience and care for tattooing really showed. Receptionist was kind and welcoming. I am grateful to have found Grey Theory and Jerry. Thank you a million times!

Hospitality was top tier. The vibes are great, feels like l've been coming here for years after just my first appt.Going for my 3rd appointment next month .Definitely recommend my guy Adrain to anyone looking for a fire piece . He does it all, takes his work seriously & is a true professional at his craft.

Melissa M.

Very great experience getting my first tattoo here at grey theory. Lupe is a great artist, she was attentive with what I was looking for and adjusted as I wanted. She took my idea and was able to make it come together. Studio is nice, clean and they make you feel comfortable.

Desiree T.

I've been tattoed by both Adrian and Lupe at different times and they are both AMAZING artists. The shop is clean and organized. The vibe is chill and very comfortable. Everyone is friendly and welcoming. My tattoos both healed fantastically and look great! I'm due for another soon and I'd for sure go back here!

Nicolas R.

Top notch work! 100% recommend, ive been getting work done from Adrian for a few years now. Only puts out bangers! Great team and staff! The whole crew makes you feel like family. Awesome vibes only! They can take your ideas/references and spin it to your own liking. Good looking out Adrian!

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

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

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 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

Sometimes in life you just want different, local nail shops in your area are great. But I…read moredefinitely took my time with this choice. I was just randomly googling different nails places near me, and this had to be about the second or third time searching google and really getting the feel of the place just from its photography and appearance. Mind you I was browsing first to find air brush, but then I came across some nail inspiration and boom. I found the "one" look I wanted. So just from the nail inspiration I wanted to find a nail place that gave me what I was feeling from the photograph, a meditation zone, a mini vacation, some earthy vibes, a peace of mind. So out of all the places I came across I chose this one, mainly because my baby nephew name is Mason, but then I looked into the website and it felt amazing just from its art , the style of nails. The appearance everything. And randomly walking in and getting paired with "yuki" she was amazing. A friendly host, we chatted a bit, but honestly her vibe was so peaceful you didn't even want to ruin the moment, her silence was peaceful enough. I sat in the middle row so I had views of outside just taking in the city and the scenery, amazing vibes. I would highly recommend trying this place out. Book with "yuki" if you can , to be quite frank everyone in there salon looks they do amazing work. Like any nail technician you get paired with with get the job done. Give it a 5 star . Thank you again "Yuki" for everything.

The studio itself is clean, modern, and exudes a welcoming vibe that immediately puts you at ease. The entire staff is not only professional but also incredibly passionate about their craft, making sure that every step of the process is personalized and thoughtful. My artist, Jerry, took the time to discuss my design in detail, providing valuable insights and suggestions that elevated my idea to something beyond what I had imagined. The level of artistry and precision was truly next level--the line work is flawless, and the shading adds such depth and vibrancy to the piece. You can tell that the artists here are not just tattooing--they are creating art that tells a story. What really impressed me was the level of care and attention to hygiene and safety protocols. Everything was sterile and organized, and they made sure I felt comfortable throughout the entire session. Even after the tattoo was done, they went over aftercare in detail, ensuring that my tattoo would heal perfectly. Whether you're a first-timer or a seasoned collector, grey theory is the place to go for exceptional artistry and a top-tier tattoo experience. I can't recommend them highly enough--I'm already thinking about my next piece! If you're looking for a studio that combines creativity, professionalism, and a warm atmosphere, this is it! read more

It takes a lot for me to leave a review, but Adrian earned it, no question. I hope this doesn't sound too, "Sales-Pitchy", but it's my honest review: From the moment I walked into the shop, everything just felt solid. Clean setup, zero ego, and the kind of focus you want from someone putting permanent art on your body. Adrian was locked in from the start. Professional, precise, and clearly someone who takes pride in his craft. The tattoo I got last night is easily the best work I've had done. The detail, the line work, the overall flow, was top tier. Adrian knows what he's doing and doesn't waste time proving it. He made sure everything was right before we started and stayed dialed in the whole session. No weird tension, no awkward moments, just a smooth, steady experience with a guy who's clearly mastered his lane. Even though Adrian was the one doing my piece, I took a minute to check out what the other artists were working on too. Every station had legit work happening, it's not just one guy carrying the shop. The whole place is stacked with talent. Bottom line: if you're thinking about getting a tattoo, stop thinking and book with Adrian or anyone at Grey Theory Studio. My only regret is that I didn't find this place sooner. My skin has officially been upgraded. read more

I'm so glad I came across this studio while searching for a shop that could do realism with a blend of anime. When I reached out, I was thrilled to receive such a positive reply to the style I wanted. I love how easy it was to book. I received a confirmation the day I made the appointment and a day before my appointment. The studio is conveniently located across from Pasadena Community College, which offers plenty of parking. Although it mentions one-hour parking, the attendant assured me it was fine to stay longer. The entrance to Grey Theory Studio is at the back, so after parking, just follow the signs that say "Tattoo"--they're arrows guiding you right to the entrance. Avoid the mistake I made of wandering around; if you miss the signs, just look up for a neon "Tattoo" sign on the second floor to help you out. The entrance door clearly displays the studio's name, so you won't miss it. The staff and artists were incredibly friendly, and I appreciated the time and care my artist, Adrian, took in customizing my design based on my preferences. read more

Met Adrian Lazaro when he came up to San Jose to tattoo people outside his shop and been going to Grey Theory ever since. His work is the best I ever seen and will work with you to get your idea down exactly right. He doesn't cut corners or rush any appointment. Also has to be the chillest shop I ever been too. Straight family and folks environment that makes you forget you're even at a tattoo shop because how chill it is. Honestly the best vibe I ever had at any business even outside a getting tattoos. All the artists there are super dope, hella coo people. Also his wife that deals with all the logistics is super chill and helps out with booking everything so you can get your date/appointment set and always follows up with you. His work is next level and lasts!... Check them out for your next tattoo and you'll see what I'm talking about. read more

I can't recommend Adrian enough. His talent speaks for itself, but what really stands out is the incredible attention to detail he puts into every piece he creates. He takes pride in his work, and it shows in the final result. On top of being an amazing artist, Adrian brings great energy to every appointment. The vibe at the shop is welcoming, professional, and comfortable, making the entire experience enjoyable from start to finish. The shop is also filled with talented artists, so you're surrounded by creativity and quality work everywhere you look. I'm beyond happy with my tattoo and will definitely be returning to Adrian for more work in the future. If you're looking for an artist who truly cares about his craft and delivers exceptional results, Adrian is the one to see. Thanks again bro. I'll definitely be returning for more work ! read more

I have quite a few tattoos from different places. This was my first time here & can say that Grey Theory is my primary source from now on. The studio itself is very clean, open, with good atmosphere & design. I got a large piece done by Adrian. He's the owner & a very talented artist. He's professional & has great attention to detail. I'm very happy with the final product. He custom designed it for me. The process was practically seamless. Trina was very helpful processing my information & setting up the appointments. From what I can see the other artists here are also very talented so I can confidently say you can't go wrong with Grey Theory Studio. Free parking is available behind the businesses. There's many food options within the small plaza. All just a stone's throw from Pasadena City College. read more

I had an incredible experience at @greytheorystudio ! From the moment I walked in, the staff was friendly, professional, and made me feel comfortable. The shop itself was super clean, well-organized, and had a great vibe. My artist, @elseloso_25, was incredibly talented and took the time to understand exactly what I wanted. They provided great input, ensuring the design was perfect before starting. The attention to detail and precision was next level--I couldn't be happier with how my tattoo turned out! The whole process, from booking to aftercare instructions, was smooth and professional. If you're looking for a high-quality tattoo and an overall great experience, I highly recommend @greytheorystudio . I'll definitely be coming back for my next piece! read more

This was my first tattoo, and I couldn't have asked for a better experience. I was a little nervous going in, but Adrian made the whole process super comfortable from the start. He really took the time to walk me through everything. You can see how much pride he takes in every line and shade. Watching the tattoo come to life was crazy, the amount of depth and detail he added blew me away. The final result came out way better than I could've imagined. If you're thinking about getting your first tattoo and want someone who truly knows what they're doing, I can't recommend Adrian at Grey Theory Tattoo enough. read more

Adrian has been my artist for the past few years now and I can't believe I haven't found him sooner! The fact how I can just explain something and he comes back from the drawing board with nothing short of a masterpiece is unexplainable. The sheer knowledge of his craft and execution is unmatchable. If you are in the Pasadena area or even traveling this is the artist to go to. I travel a couple hours away every time I get tattooed from Adrian and every minute in that chair is worth it. Looking forward to my next piece from Grey Theory Studio. read more

The vibe, service and overall quality of this place was AMAZING. I went for their Friday the 13th flash sale and honestly loved Adrians work. He did 2 tattoos and me. Plus I had 2 other friends that got tatted by 2 other employees and we all LOVED this place. If you are thinking of a tattoo locally look no further. These people got you covered and are amazing with recommendations and advice for your tattoos as well. Very knowledgeable and very creative team! Will be returning read more

I've been going to Daniel for almost 5 years now. He always does amazing work and for incredible rates too! I've gotten my half sleeve (forearm) done with him and we're 3/4 the way done my leg sleeve now. I get compliments daily on the work he has done for me. Daniel always is ready to start the next project. I can tell he really loves what he does. If you're looking for a very talented realism artist i'd suggest you book here. read more

Great great experience! My first visit. Everyone I spoke with was welcoming and helpful. Lala helped with the paperwork :). Lupe was my artist. She welcomed me immediately and asked about my ideas for my tattoo. She got right on drawing them out to my specifications. The drawings were awesome and she helped with the placement as well! My tattoos came out AMAZING! I am so very happy with this studio. I definitely will be back! read more

Grey Theory Studio is a clean and reliable tattoo shop. Adrian, the shops owner, is very talented and professional. He will take care of your needs regarding tattoos (size, placement, etc). My boyfriend has had a lot of work done by Adrian. Please see the attached photos. I also got work done by another artist. I felt comfortable and welcomed. Overall, Grey Theory Studio is a great tattoo shop and I recommend it 100%! read more

Lupe is actually a goated artist. She's helping me get a matching tattoo that my father has that is really detailed, and her style just makes it pop out so much despite it being traditional. It was honestly really peaceful chilling in the studio while she worked on my tat. It's nice, clean, and organized, and she's an absolute professional as an artist and super chill and friendly as a person. Highly recommend! read more

I can't say enough great things about Adrian Lazaro at Grey Theory Studio! From start to finish, the experience was incredible. Adrian has an amazing eye for detail and a true talent for turning ideas into stunning pieces of art. I took the time to listen to his vision and worked with him to create a design that exceeded all my expectations. If you're looking for a talented artist I highly recommend Adrian. read more

This is by far the best place to get any tattoo. It's still a private setting. My artist Adrian took time to customize each piece I've gotten from him. This is definitely the only tattoo shop I have felt comfortable in. It's open so you don't feel so close to other artists, it's clean and comfortable. My artist took his time in creating my design and his portraits are out of this world! Highly recommend. read more

Adrian Lazaro at Grey Theory Tattoo Inc, who recently did my gladiator tattoo, is an amazing artist! I am a repeat Clint that travels to and from Las Vegas because of how talented he is. The shop is a fantastic atmosphere, very cozy and chill as there are plenty of resources for food, drinks, coffee, and shopping. All of the artists there do great work as I had the chance to watch them at their craft. read more

Where do I begin. Well... I have both leg sleeves, both arm sleeves and currently working on my chest plate! Adrian is a very gifted artist! My work has been awarded several trophies because it is top notch! I'm really looking forward to my chest piece since I know I will be getting the same quality work! If you are looking for a black/grey artist, look no further, you will not regret it! GTS!!! read more
