It was more of a viedo than slides, and yes it was helpful and it promted more questions for me to ask when I went for my consult. The consult was when I was able to meet everyone. I was at the office for about 3hrs, but I didn't mind since I saw everyone at once!
I understand you wanting to meet everyone, I would see if they will send it to you and you can watch it and if you feel comfortable from that then you can go for a consult and if you don't then you can still go on the 25th....just something to think about.
