How do you know who's a good surgeon besides reviews? Which don't really always tell the truth

It sounds like a funny question, but I'm one of the threads here people were saying to make sure you find a " good surgeon." I followed up on recommendations from other people and met with surgeons but everyone's spine is different. So how do you know the real scoop on a surgeon? I think the simpler your issue is obviously it's easier for any surgeon. So I guess my real question is how do I find a surgeon who is skillful with complicated for high risk spines which I have been told by falling in that category. If anyone reading this as been told their spine is very complicated, and they needed more than two levels fused please get in touch with me by a chat. The other question is experience / years the surgeon has been working. Recently I was referred by a very well-known surgeon to one of his young colleagues. I looked up his credentials and he went to the best schools but he's only been doing spine surgery for 9 years. I'm not sure if that's enough time to really know how to deal with complications that can come up. Any opinions?
