I did an internship 2 years ago for a very large and well-known animal sanctuary (I don't want to say which, because I still like their work even though I'm upest right now). I worked 40 hrs a week, for three months, doing hard manual labor, in gross winter weather over christmas holiday, assisting on all animal healthcare duties. It was an unpaid volunteer position, and I turned down a well-paying job to do the internship because I wanted to help the animal sanctuary (for the same reasons I'm going to vet school). While I was there I sat down with the intern coordinator and told them I was going to apply to vet school and would I be able to get a LOR from this group. They said yes of course they would keep my information on file and my performance was great. Now I'm applying this year, and I've called them twice (left voice mails) and emailed the intern coordinator and the main location email, all over the course of two months, and over a month later they still have not responded. I was counting on them! Now I have to find someone else. You'd think it would be in a sanctuary's best interest to help someone get into vet school who aligns with their core values and clearly states in all communique that they plan to do shelter medicine including for at-cost care for animals at said organization. But no!
