Their first joint project was the short Her Bounty (1914), and their first feature-length film was Father and The Boys (1915).
Most of the titles that the two worked on together were for Universal"s Bluebird label. Park made her solo directorial debut in 1917 when she directed The Flashlight starring Universal"s top dramatic actress Dorothy Phillips.
