Healthy Private Chef

I am in need of someone to prepare and teach me how to cook healthy meals for my family.
On the east coast, I've heard of chefs coming to your home, preparing a variety of healthy meals for your family and then teaching you how to make the meals that your family prefers.

Does anyone know of a person/service like this out here? I live in the west San Fernando Valley area.
I've tried searches online, but am not coming up with a lot of options.

Thank you!!
