Dont know about retreats but they definitely have groups and bible studies for all those. And mission trips!
Adding more to Tajiri's answer. They do have wonderful conferences for both groups, my personal opinions, it's as good as going for retreats. I do love how GODS word is being preached here. So realistic, delightful and practically applicable in one's life to grow spiritually deep with GOD. I can say that for my wife and I. The marriage conference that happens every February of the year we don't miss it! We can't wait for the 2020 conference to come.
