Thnx Gidji. I've decided no to limit myself to a strictly 3-Day Event coach but I can not go to someone who only does dressage. I am hoping to make a career out of horses and I need to continue showing to get a good reputation. I don't think it'd be good to take a year off from my discipline.
Doing dressage is not taking "time off your discipline". Dressage is a huge part of 3 day eventing.
