Second opinion as to whether a depressed man can benefit from a lifecoach

Is it alright for me to coach a man who is depressed and is jaded about the many coaches and psychiatrists he has already seen
I feel its okay because his bosses don’t think so and has given him a promotion and perhaps he is overwhelmed. I wanted a second opinion

I am a Life Caoch ( trained by Curly Martin ) and she would say NO
Stick to your knitting !
