Hmm, I'm going against the grain in saying this, but I wouldn't do two therapists. I've done it once, when I was away at school. I would see a therapist when I was at school and one when I was at home. They did contact each other (the therapists) but honestly, it was more grief than it was worth.

I considered seeing two directly at the same time, but one was a DBT therapist with a DBT group and in DBT you aren't allowed to see anyone other than your DBT therapist.

If you find this other one interesting, you can just tell your regular T that you're interested in her approach and would like to see her to see if she can better help.

Are there any other options for grief group therapy where you live?

I know others posted about how if you're working on two different things, it could work. The thing though, is that everything is often interconnected so even if it was separate issues, they would likely come together at some point and then you're going to have to deal with two different therapists approaches to the same issue which could be complicated and potentially harmful to your recovery, if they have different views/approaches/thoughts.
