I just stumbled upon the Sassmannshaus violin method. I am on a local music school’s email list and apparently they have a Sassmannshaus instructor. This method teaches reading and playing at the same time, is a “classic” program originating in germany. While looking up more info on it, a program called Jump Right In was also mentioned. So, these programs might be worth looking into if you do not have a Suzuki school near you or if you prefer to use a method that teaches reading and playing at the same time.
