Does anyone have any dog training recommendations in Chicago?

I just moved to Chicago from Portland a little but ago and have a German Shepard and Cattle dog mix. We’ve done a lot of training before moving across the country. But I’d really like to continue with a good trainer once we’re settled in more, preferably one who works with/specializes herding breeds. Trying to work on our recall and were recommended (by our former trainer) working with a trainer who can teach me how to use an ecollar. If anyone has any recommendations I would love them!
