As a teenager, Loren promoted comic conventions and record collector shows in the Detroit area. He moved to San Diego, California, in the late 1980s and started Musicade, a mail-order music memorabilia company. In 1989, he sold Musicade and started Revolutionary Comics, which produced Rock 'N' Roll Comics, a line of unauthorized comic book biographies of rock stars prompted in part by the success of an unauthorized Bruce Springsteen parody comic called Hey Boss. He hired Hey Boss artist Larry Nadolsky to draw the first issue of Rock 'N' Roll Comics, which profiled Guns N' Roses. Loren's father, Herb Shapiro was the vice president of the company operating Revolutionary Comics, Infinite One Inc.

Loren was also the first publisher of the Carnal Comics line, which is still publishing comics in 2011. From 1994 to 2000, the Carnal line was run by former Revolutionary Comics managing editor and head writer Jay Allen Sanford. The series was subsequently published by another of Loren's Revolutionary Comics artists.

Tragically In June 1992, at the age of 32, Loren was found stabbed to death in his San Diego condo.[1] The case remains unsolved.

Loren is interred in El Camino Memorial Park, in San Diego
