I think that you can do some home desensitizing, but I'd definitely get the help of a trainer to really instruct you once things get farther along.
Put on her halter on her right side so that you can keep her with you, and it might be helpful to get a very long lead or a lunge rope (a 22ft line should be great). You can also use this method to teach her how to tie, once you get to that stage, as long as you have a tie blocker ring.
Start by just standing on her left side, letting her run out on the lead line until she feels comfortable with the space between you, then gradually bring her back in, making sure you stay on her left side. Eventually you should be able to touch her, and then brush her, etc, and all the while just work on leading her from her left side versus her right. Don't get aggravated or aggressive with her, talk in nice soothing tones and if you get frustrated just stop, because it won't help her feel comfortable with you.
However, also make sure you rule out any vision problems before thinking its a training problem. We have an old TB who's blind in his left eye. If you just try to lead him from the left, he's pushy and rude. If you talk to him while you lead him from the left, he's a little better, but he still kind of walks ahead of you. If you lead him from the right where he can see you, he walks very nicely and on pace with you.
