I'd not say my issues are completely resolved yet, but significant reduction in suicidal ideation for me came from resolving other issues that made me feel like suicide was the best option.
I'm not sure what such a center does in the US. I know in my country we have some places where you can go when you feel suicidal. They host you until you feel better, similar to a hospital stay. They don't really treat the underlying issue, they look that you're safe until you can get help for the stuff causing you to feel this way again.
