I'm not crazy about online dating sites.
The advice I've always heard is focus on what you like to do and then go do those things to meet like-minded people.
Do you run? Join a local running club. Play a musical instrument? Find a worship band to play in or hang around places that play the kind of music you like to play/hear (not bars
). Do you play chess? Go find a chess club. Do you love to work in your garden? Join a local gardening club.
Do you have any particular medical ministry in mind? If so, why don't you join them now by donating money and going to their meetings?
In order to find someone like-minded . . . you have to do those things you like.
