Really dig the Pi logos. I actually like the squares, but I also kinda dig smart juxtaposition.
My only critique is pretty nitpicky.
As for the assist logo - it doesn't say 'assistance' to me. My suggestion would be to have the letters linked with each other rather than the super close keming - kind of how the boxes in the 'link' logo intersect. Does that make sense?
Also, and this may be because there are a fair number of Clemsonites around here, but the 'assist' logo with the three people in blue and orange is kinda of making me see a tiger paw.
Overall, that's some pretty great work.
