I've made a few changes.
Good luck to you!
This year I am applying for an internship with AAA, Inc., CITY, WI. to work as research assistant for 12 to 18 months.
You might know that AAA is an equine-nutrition research and consultation company serving both the horse producer and the feed industry. Its goal is to advance the industry's knowledge of equine nutrition and exercise physiology, and to apply that knowledge to produce healthier, more athletic horses.
Perhaps you remember I am a PhD student interested in equine exercise physiology. I am definitely sure this internship is an ideal opportunity to gain invaluable experience and expand my research skills into specific areas.
Like other employees of BBB I received a reference letter at the end of the summer in 2006. I worked there for four seasons and you were my supervisor during that time. I believe you know me quite well and I think you also liked my performance. Therefore, I would really appreciate if you could write me a letter of recommendation concerning the time I work for you.
Thank you very much for your time and consideration. I look forward to hearing from you.
