Do you have references of people who have used ESAC in the past for internships? Would I be able to contact any of them?

YES! You can contact Jackie:

“I think this is the best opportunity anybody has ever given me, thank you! I have learned more in two days here talking to the Marketing Director at Holmes Place than I have for four years in school. This has been an amazing internship and I can see why this company is so successful. I can’t thank you enough for giving me this internship opportunity and I am definitely starting to get some direction of what I want to do after school.” — Jackie Koehn, (UPenn)
