Mentor Recognition: Sarah Lennon '90

Article Type 

With this ongoing series, The Rockefeller Center recognizes the valuable contributions provide by its alumni mentors to participants in the First-Year Fellows program. The First-Year Fellows Program provides students with opportunities to meaningfully engage in public policy early in their Dartmouth career. Students are placed in fellowships with Dartmouth alumni in Washington, DC, serving in policy positions where the supervisor is willing to take on a significant mentor role.
"I decided to be a mentor/supervisor because I remember how daunting it was trying to find a job after I graduated and in the summers, not really knowing what the work environment was like. Additionally, I recall writing papers in college and graduate school where I thought I understood how it all worked, only to find out after getting to D.C. that I was completely misguided. So, I hope that by mentoring a First-Year Fellow, I can help him or her become a more informed student, citizen, and potential job applicant, helping to bring more Dartmouth to DC!" --Sarah Lennon '90  Sarah G.J.
