Steve James' affiliation with Kartemquin began in 1987 with the start of production of Hoop Dreams, for which he served as director, producer, and co-editor. He has since then become one of the most acclaimed documentary makers of his generation, with noted works being Stevie, The New Americans, The War Tapes, At the Death House Door, The Interrupters, Life Itself, and most recently the 2018 Academy Award®-nominated Abacus: Small Enough to Jail.

Artistic Director and founding member of Kartemquin Films, Gordon Quinn has been making documentaries for over 50 years. Roger Ebert, of the Chicago Sun Times, called his first film Home for Life (1966) "an extraordinarily moving documentary." With Home for Life Gordon established the direction he would take for the next four decades, making cinéma vérité films that investigate and critique society by documenting the unfolding lives of real people. 

Peter Gilbert is one of the filmmakers who made Hoop Dreams, serving as a Producer and Director of Photography. The film won numerous awards including The Sundance Film Festival Audience Award, Producers Guild of America, Independent Spirit Award, and The Robert F. Kennedy Memorial Award for Journalism. Hoop Dreams was on 100+ top ten lists for 1994. Also with Kartemquin and Steve James, he recently finished At the Death House Door which premiered at South by Southwest in 2008, and won awards at several other festivals following, including the inspiration award at Full Frame. It aired on the Independent Film Channel in May of 2008.

Adam D. Singer began working with Kartemquin Films in 1989, spending 5 years on the critically acclaimed documentary Hoop Dreams, and has continued his association with them ever since. He has worked on various productions, both nationally and internationally, as a producer, cameraman and sound recordist. With Kartemquin and director Steve James he produced No Crossover: The Trial of Allen Iverson which had its world premiere at the SXSW Film Festival and aired as part of ESPN Films' 2010 International Documentary Association award-winning series "30 for 30." The film was selected for the IDOCS International Documentary Forum in Beijing, and also played at the Cleveland, Full Frame, Dallas, Nashville and Atlanta film festivals, among others.
