Past Intern Testimonial
"This opportunity has played a pivotal role in shaping my career, and since the end of the internship, I have acquired a full-time position on the High-Speed Rail Project. I am certain this is thanks to the internship. It has opened the door to work on an incredible project with talented engineers to learn from. I would be remiss if I did not mention the incredible support I have gotten from the Luster staff. Not only was it a privilege to work alongside such highly skilled and experienced engineers but what set this experience apart was the workplace culture. Every staff member I interacted with was very kind and willing to share knowledge. This not only made coming to work enjoyable but has also instilled confidence in me to strive for more in my career. I am also extremely appreciative of Sheldon Eskelson and Robert Luster who have reached out even after the internship program has ended simply to check in and offer advice. Luster is truly a rare company that strives to do what is right for their employees and I could not recommend this program enough for other engineering students."
