I worked with them recently as their Creative Director to help develop an e-learning program that integrated learning management tool into our curriculum for students who were about ready be licensed teachers themselves! They made it easy enough so we could get through but also complexed just right such they didn't overwhelm us or make things too difficult (we're not designers).
The process was seamless from beginning contact until project completion including delivery dates/deadlines which is always important when you have very tight deadlines like ours did :) Great communication throughout - nothing at this point can really go wrong if everything goes well ;).
