I wanted to put my gratitude at my recent promotion into a letter so that it may go on file for others to see. I wanted to let you know just how much I appreciate the opportunity and responsibility that goes along with being promoted to Regional Sales Manager. I feel it is an opportunity I have earned and will not disappoint you with my performance.
When I stared with Justin Hobart eight years ago, I made it a goal to reach management before my 10-year anniversary. Thanks to your dedication to my development and success, I was able to move into a position where I could reach those goals. The realization of this professional dream will act as only the beginning to a long and prosperous managerial career.
Your guidance and advice has been invaluable in helping me to achieve this goal. I wanted to thank you for taking so much time out your own career to make certain that I was able to achieve all of my goals.
It is now my job to show that you made the right decision and that you have put a competent manager in place. If you need to discuss this further, please feel free to call me at 000-000-0000 or email me at firstname.lastname@example.org.
