When she is there don't press stop in PT while the vocal is running through the verb, or she'll hear tons of it.

You could try a bigger room to record the vocals in, maybe with an omni mic or something, even micing the room separately. She's probably heard something that she really didn't like that had tons of reverb on it. I worked with an artist that had an "aversion" to reverb, because they had always associated it with the spring reverb on their guitar amp. Ask her to bring in an example of what she wants the vocal to sound like. Reverb is a part of life, it's natural, and we hear it constantly everywhere we go. We would all have to live in vaccuums to avoid it. Turn up the reverb where you can just start to hear it, and then back it off a little.
