Multiple separate switched from common feed

I have 3 separate single switches, controlling three separate lights, all powered from one common feed from a receptacle below. I would like a little oversight on my wiring please. Basically, from the power feed black wire I have three black pigtails, one to each switch. Then the 3 switch side whites connect to the power feed white and the 3 switch side grounds get connected to the power feed grounds. Right? Or do I provide pigtailed grounds to each switch as well? I have a couple of these situations I am not exactly sure of, and my inspection is probably gonna be Tuesday. Thanks for all replies.
