    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

    The template was amazing.

    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

    New addition
    Karen R.

    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

    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.

    Two flash tattoos for Friday the 13th

    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.

    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.

    Aftercare.
    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!

    Hi there ! Here to support my friend Jazmins review . I had a similar experience the same day when…read morehaving my piercing swapped out. When I was there, I personally did not see any visible sanitizing process. I saw the piercer remove the jewelry directly from the bag, and from my viewpoint, it did not appear that it was rinsed or sanitized in any way before being used If the business is certain that their sanitizing procedures were followed and are confident that the cameras would show this during both my friends & my jewelry change, we request that they share the footage with us. If the video clearly demonstrates that we are more than happy to take down or update our reviews. Lastly as of today my friend has a small bump on her nose at the site of the piercing which is why we felt it was impotent to speak up about our experience.

I was greeted by the nice lady in the front who helped us pick a nose ring. My review is mainly for the piercer, when I sat in the chair, he didn't greet me and I saw him grab the jewelry and rinse it under the faucet for 2 seconds. He never washed his hands and he put gloves on dirty hands. He then proceeded to remove my current jewelry, and never swabbed my piercing hole with anything. He just began placing the new ring which I never saw him sanitize. Through out the whole process not once was anything sanitized. He also seemed off like he was a drug user. My friend had the same experience and also co firmed she never saw him sanitize anything when he was servicing me. NEVER AGAIN, I regret coming here. I hope I don't get infected.

    If you are reading this you are about to met your new tattoo Goddess. Shannon is everything you…read morewant in an artist. Super creative, highly skilled along with light handed and fast. Totally cool chick and engaging! I came to her after looking for an artist for 11 yrs. to fix a mistake. My first piece was 12 hrs. and I thought the artist had gotten my vision. They didn't. It was a botanical piece and it was flat. Not what I had drawn. Unfortunately, it was on my back so I couldn't see it. Shannon totally fixed this piece. Recolored it. Shaded it and made it come alive. And it only took her 2.5hrs! She is that experienced. That skilled. We've spent close to 35hrs together now. I now have a stunning girdle, gorgeous Arabic line work weaving, a delicate back piece, side scroll saying in Sanskrit cursive and random exquisite butterflies all over my torso. Each step was well planned and a collaboration. Her background in serious Art Design schools shows. Go see her book! It is just mind boggling how many styles she has produced...Greyscale, abstract, gothic, photorealism, whimsical, tribal, ethnic, white, modern so many more that I don't know how to describe. You dream it, she'll create it!

    I can't say enough good things about Shannon O'Sullivan and the Shangri-La Tattoo experience. I…read morelike that Shannon draws her own art. I sent her a couple of pictures I liked but talked about what I wanted to change and she took it from there. Shannon is a bad ass, magical queen and it is a privilege to sit in her chair honestly. She is very thoughtful when placing and sizing the tattoo, so once she goes to ink you have a really good idea of the outcome. Just top notch all around.
