Oh ok, I was mistaken Savannah. I did a little reading after talking with a Black Rock Ranger about a "green dot" call he had to deal with, and felt unequipped for, in 2013. I have never been a ranger myself, so I wanted to look into how those situations should be handled. From this basic reading I learned about these two groups (Sanctuary and Zendo), and somewhere along the line, I got the idea that Sanctuary turned into Zendo. I am not involved with the rangers, Zendo, or Sanctuary, so I never got corrected on this.
After way too much reading (luckily I had some free time tonight), I still can't find the article where I got this idea from, but I found three that might give a clue as to why I thought this was the case.
This one from 2005 talks about how the organization that now runs Zendo used to help the Black Rock Rangers staff Sanctuary.

This second one from 2013 describes what Zendo does, and what they do sounds similar in some ways to what the article above says about Sanctuary.

This last one talks about why the organization that helped staff Sanctuary stopped working with Sanctuary, and this may very well be the reason why I thought Sanctuary was no more. After a more careful reading, I am now realizing that it is saying they just stopped helping at Sanctuary, not that Sanctuary went away.

Both seem to offer psyche support, when medical/LE support is not needed (freeing up medical/LE staff for medical/LE emergencies). Both also seem to have a calm, supportive space, and compassionate, trained volunteers for people who are in a bad head-space for whatever reason. It seems like they are two different organizations though.
Well, now I know that there are three locations for psyche support on playa, 2, 6, and 10.
