Here are letters of recommendation from the supervisors at the only three post-college full-time jobs I've ever had. I didn't select these people — they just happened to be whom I answered to at each job. And with the exception of the first few months I was at Gateway on a part-time basis in 2003, they each were my supervisors the entire time I was each of these companies. 

Recommendation from Crystal Schelle (supervisor at The Journal)

Recommendation from Alan Wallace (supervisor at Gateway Newspapers)

Recommendation from Kevin Naff (supervisor at Washington Blade)
