How to Say I'm in Charge of a Company

You may also want to just say something very briefly about who you work with. This is especially important if you are a company that has lots of different areas within it. In English we say I'm responsible for or another way that you can say this is I'm in charge of. Remember all verbs after prepositions are in the gerund. Now when we have something afterwards we can either use a noun, for example I's in charge of marketing or we can use a verb,. but it must be in the Gerund because for and of our preposition.
