Write a letter in about 100 words to inform a colleague of a coming partner. Do not sign your own name at the end of your letter, using “Li Ming” instead. Dear Henry,
I want to take this opportunity to inform you that Claudia will be joining us shortly. She holds a doctors degree in genetics and has worked in this field for twelve years. It is exciting that she has decided to join our company in this transformation period.
She is a person who is good at time management and I have no doubt you will find a good partner in her.
Claudia is currently involved in a project which might be of interest to you, and she shall be contacting you immediately after her arrival. I am sure that you will soon join hands and make progress step by step.
Sincerely yours,
Li Ming
