Steven grew up in Roseville, California, and began his professional experience at age 15 as a paid intern for an environmental engineering firm in Lincoln, California, focused on groundwater remediation. This role introduced him to hazardous waste management. After five years with Applied Engineering and Geology, Inc., he enlisted in the United States Navy’s Nuclear Propulsion Program, driven by both patriotism and an interest in nuclear power and submarines.
After completing training as a nuclear machinist’s mate, Steven served from 2013 to 2018, primarily aboard the USS Georgia (SSGN 729). His service included extended periods in the Indian Ocean, Diego Garcia, the Mediterranean Sea and Crete, Greece. During this time, he advanced to the rank of E-6 and became the Machinery Division leading petty officer.
During his final deployment under his initial six-year contract, Steven met his future wife on Diego Garcia and reenlisted for orders to Guam as a radiological controls technician to be closer to the Philippines. After completing Radiological Controls Technician Qualification School, he married and moved to Guam, where he served as environmental monitoring program manager from 2018 to 2020.
Following the birth of his first daughter, Steven and his family relocated to Galt, California, to be closer to extended family. He considers joining Lawrence Livermore National Laboratory a highly positive step for both his career and his family.
