I run the ancient language Meetup in the Seattle area. While we primarily attract Latin learners, there has been some interest in the past for Greek. Unfortunately both of the other people that I started meeting with left, so we are back to Latin only at the moment. I am just learning myself (unlike with Latin which I've studied, read and spoke for a few decades), so I really need a stronger speaker to help guide. I suspect there are others in my area, but they have not yet found the Meetup or cannot attend for whatever reason.
