Federation Ink Tattoo Parlor operates a custom tattoo studio at 4683 30th Street in Normal Heights, San Diego, at the intersection of 30th and Adams Avenue in the 92116 ZIP. Owner Keith Greene runs the shop alongside artists including Michael Miazio, Marlin, and Holly Lotus, each bringing a distinct specialty to a roster that covers Japanese traditional, photorealism, neo-traditional, and blackwork styles. The studio shares the 30th Street arts corridor with Ashton Gallery at Art on 30th, the fine-art exhibition space one block south that represents the same intersection of visual craftsmanship and independent creative production. Federation Ink focuses exclusively on custom designs drawn from client consultations rather than flash-sheet selections, with each piece sized and placed during an in-person layout session before needle work begins. The shop sells its own merchandise line of 100-percent cotton T-shirts, locally designed and printed in San Diego, available in standard adult sizes and a dog-sized run. Adams Avenue foot traffic spikes during the annual Adams Avenue Street Fair each fall, when the Normal Heights corridor between 30th and the Kensington sign becomes one of San Diego's largest free music festival grounds. Keith's long-running client base includes repeat visitors who return over multiple sessions to build large-scale back pieces and sleeve compositions that require layered line, shading, and color passes across separate appointments. The streetwear and art-supply inventory at Gstyle Shop on Adams Avenue draws from the same Normal Heights creative community that gravitates toward custom ink. Federation Ink's 30th Street storefront is accessible by wheelchair at the entrance, with free street parking along the block.
