The guys on the pier. I think it's Catalina Divers Supply. They did a pretty good job. But, they were understaffed for the gear renting and it took a LONG time for a boat-full of divers to get their gear and on the boat. Also, I found it surprising that the trip's Dive Master never got in the water. He just pointed here and there and suggested where we might go. I guess that's common there, but I'd not see that before. If doing it again, I think I'd just dive the little marine park there and go in from the shore. But, it's all good.
