Dash Mihok was born in the West Village of New York City on May 24th, 1974 to parents with ties to the New York stage and was raised in a trendy artist building. He attended many different schools including the Bronx High School of Science during his freshman year in 1988. While going to high school, he participated in City Kids, a foundation in New York City whose purpose is to "engage and develop young people" through programs dealing with self-esteem, leadership, and communication starring a group of multi-ethnic teen actors and Jim Henson's muppets. Dash was part of the City Kids Repertory, which puts on productions all over the city.

Much of the New York native's early work was lensed in his hometown. The young actor appeared in guest spots on the NYC-filmed dramas "New York Undercover," "NYPD Blue," and "Law & Order". Mihok made his starring film debut in the 1994 racially-themed independent feature "Black Is White" before receiving particularly strong reviews for his role as a mentally-unbalanced young man in the CBS TV-movie thriller "Murderous Intent". An appearance in Barry Levinson's hard-hitting "Sleepers" followed. While Mihok's performances in these New York-filmed features were strong, he first gained real notice with his featured role in Baz Luhrmann's modern take on "Romeo and Juliet".

He was a featured regular on the CBS sitcom "Pearl", starring as Rhea Pearlman's rebellious son Joey. He also had a 1999 recurring role on The WB's college drama "Felicity" as Lynn, a competitive swimmer attending the fictional University of New York. He has also had a guest appearance on "CSI: Crime Scene Investigation".

To date, he has been in a variety of independent and high-budget films, the most recent of which being "The Day After Tomorrow" and the upcoming "Mojave" (as of May 2004).
Danced his way through the music video "So Pure" with Alanis Morissette; the couple was dating at the time. Played Eamon McBride in the pilot for "Love & Money" but was later replaced. Favourite book is "The Last Hours of Ancient Sunlight" by Thom Hartmann. Was named after famed writer Dashiell Hammett. Admitted to suffering a bruised ego as a result of the cut his role in "The Thin Red Line," as the bullish Doll, took in editing. His subtly intuitive performance, while truncated, was still among the most moving. Has been formally trained in acting and dance. Favourite food is sesame chicken, favourite drink is Arizona green tea. Favourite shoes are Pumas. Enjoys horse-back riding, swimming, drumming, and rapping in his spare time. Is the subject of two Alanis Morissette songs, "So Pure" and "That Particular Time". Is featured on the Sabac album "Sabacolypse", in the song "I Have A Dream".
