I'm over in Tigard and I'll happily join another game in the SW suburbs. A certain pandemic killed several of mine.
If you don't get responses here, I've mostly assembled groups in the area through the discussion board of the local "Dungeons and Dragons (5th edition) for newbies" Meetup group, which seems to be the most active non-AL Meetup group for Portland D&D, and despite the name has plenty of non-newbies. I've only once gone to an actual posted event there, since the nature of forming a D&D group doesn't really jive with the way Meetup events are formatted, but the discussion board was a solid place (pre-pandemic) to say you were looking to start a group and get responses. It all seems to be in the process of re-emerging from its chrysalis right now.
I also used to go to drop-in games at Gongaii Games in Beaverton most Tuesday evenings in the before times. They closed for the pandemic but are evidently going to start hosting players again July 1. Neither of the people who hosted/DMed the games I went to there in the past are in town anymore but I'm hoping someone or other from amongst the old regulars there will be inclined to get drop in games going again in the near future. It was a great way to meet lots of RPG players in the area with very little commitment.
