After leaving the Marines in 1975, Rudy began his career as an apprentice at Goodtime Charlie’s Tattooland, in East Los Angeles. Under the watch of Charlie Cartwright, a friend he met while visiting the old Long Beach Pike, Rudy and Cartwright began to hone their craft of single-needle, black-and-gray style tattoos. Rudy is known for his use of light and dark shades of black and grey. In addition to creating a softer and more realistic style of tattooing, with the advent of the new single needle tattoo technology, artists were now able to use a much greater level of detail than previously attainable utilizing older and more readily accepted tattoo machine and needle configurations. As the client base of East Los Angeles began requesting this 'penitentiary-style', the pair decided to create a single-needle configured tattoo machine.

Rudy is currently the president of the Beatnik's Car Club - a car club which requires the members to own 50s-styled hot rods and 'lots of tattoos'. He is the owner of Tattooland, an 'old school' street shop, located in Anaheim, California-Wiki
