Pratt began his career with Oklahoma's Midwest City Police Department in 1965, where, as a police officer, he completed his first composite drawing that resulted in an arrest and conviction. He joined the Oklahoma State Bureau of Investigation in 1972 as a narcotics investigator and retired as an assistant director in 1992, retaining his position as a full-time forensic artist. Pratt fully retired from the bureau in 2017. This work helped in several high-profile cases both on a national and international level, including the Oklahoma Girl Scout murders, the Oklahoma City bombing and the 1993 World Trade Center bombing. For his work with the OSBI he was inducted into the Oklahoma Law Enforcement Hall of Fame in 2012 and the Oklahoma Military Hall of Fame in 2019. Pratt received awards for his artwork at Inter-Tribal Indian Ceremonials, Gallup, New Mexico, and Red Earth Festival, Oklahoma City, Oklahoma.

The Smithsonian's National Museum of the American Indian chose Pratt's Warriors' Circle of Honor, a 12-foot tall, stainless-steel circle balanced on a curved stone drum as the centerpiece of the National Native American Veterans Memorial. The memorial was installed outside the museum in 2020, but the official in-person dedication ceremonies did not take place until Veterans Day weekend of 2022 because of the COVID-19 pandemic.
