Dear Mr. (insert name)

I wished to thank you for being such a supportive, kind, and helpful colleague. My first days at the company would’ve been quite disastrous had you not been there to show me the ropes. You always tried to take out time to help me get the task done right, even if you were swamped with work.

I could never thank you enough for all your help over the years. Even if I made a couple of mistakes, you were always extremely patient and understood that I was a rookie. In team dinners you made me feel included when I felt like an outsider. My time at the company was as good as it was partly due to you.

You even went above and beyond to help me look for new opportunities and helped me practice for my interview. Now that I am leaving, I hope that every new recruit gets the opportunity to work and grow with a coworker like you.

Wishing you well

Dear (insert name),

Thank you for being such a wonderful mentor. I am truly grateful that I got to learn under the guidance of someone like you. My very first days at the company would not have been easy if not for you. I felt like a fish out of water, but you took out time to advise and teach me. You were very busy yourself, but always helped me when I faced a problem. My transition from a student to an office worker was smooth because you were there to guide me through it.

I never felt excluded in the office because you included me in team discussions and dinners. My work at the company is good today because you corrected me whenever the need arose. You armed me with the knowledge that I use even today.

I can only hope to be as good a mentor to the new hires as you were. I will be sure to guide them to the best of my abilities and pass on all the knowledge they need.

Best wishes,
