As always, the best way is to already know them or have a shared connection with them - have a wide network.
Do you have frequent social interactions with other professionals? Off the top of my head (and from personal experience) some ways to meet people:
- Network within your company, particularly with people in other disciplines
- Alumni events for your college
- Send your kids to private school and make friends with parents (or have gone to private school yourself)
- Play sports that professionals play like golf, tennis, pickleball?
- Attend networking events (though I haven't really tried doing this since covid)
- Get an (in-person) MBA
- Marry/date someone with a wide network
