To Whom it May Concern，
I'm writing this reference letter on behalf of ***. I've been his/her supervisor for **** years in **** University. In just those xxx short years, I've watched him/her rapidly advance from an entry-level position to a Senior **** Representative. I've never hesitated to recommend him/her for promotion when his/her time came.
*** derives satisfaction from helping his/her classmates troubleshoot problems. Many of those who've received help from xxx specifically ask for him/ her when they again contact support, and for good reason: he/She is professional, courteous and quick to help. His/Her skills are sharp and without prompting, he/she keeps them honed to a razor's edge. I often see *** in our lab before or after work hours, replicating problems. Additionally, *** doesn't abandon his/her friends when the whistle blows. He/She sticks to it even after hours, until he/she resolves the problems.
*** is a team player who is always willing to share the knowledge her sponge-like brain soaks up. For example, thanks to his/her willingness to share the trouble-ticket notes he/she so meticulously recorded and compiled, our ****Department was able to manage/craft "*******" step-by-step, online troubleshooting guides for our field engineers. Consequently, we've seen an increase in customer satisfaction, a reduction in ***calls, and a significant savings on the department's bottom line.
I have nothing but good things to say about *** and I'd strongly recommend him/her for any endeavor he/she chooses. Please don't hesitate to contact me if you'd like to hear more good things about xxx.
Sincerely,
