Welcome Micah. I'd suggest that you do some obedience first, then use obedience classes to help get your dog used to other dogs in a controlled situation first. Unless your dog already goes and you know he's fine with other dogs! If so, you might look for the local basenji club and ask if they have meet ups.
You might start here, they seem to have some fun meet ups!

They are trying to set up meetups at least once a month. With the COVID-19 virus meetups were on hiatus but now that some dog parks are opening up meetups for Basenjis are starting up again. I live in San Diego so I really have to think about driving 1.5 hours with 2 senior Basenjis.
