Justin Killingsworth, founder and principal, launched JMK Engineers after more than a decade of working for large, traditional firms in Kansas and Hawaiʻi. As a multi-discipline mechanical and electrical engineer, Justin developed a trusted client base that relies on his multidisciplinary expertise, the quality of his technical work, and timely services. Prior to JMK's launch, Justin's portfolio included a diverse set of projects & clients including medical facilities, K-12 and university education projects, large-scale Hawai'i resorts, Kamehameha Schools, and a large, modern, self-sustaining estate in Hawaiʻi.

After building upon his earlier practice, Justin founded JMK five years ago to break from a traditional firm and become a leading partner in the industry, serving select clients across the Hawaiian Islands and beyond.
