French to English Marketing Media / Multimedia Events agency

I have a document which is purely a list of staff at an events agency with no more context.

The top of the list is:

Directeur agence
Directeur associé
Directeur conseil
Directeur clientèle

When I look up "directeur conseil" it seems to be a specific term for media / communications agencies and the closest translation I find is "account director". However, I find the same translation for "directeur clientèle".

Could anyone help me find a way to distinguish between the two?

Thanks very much for your help.
