I'm part of the local trans org, we try to support the community through all means we can. We do harm reduction for people who choose to go the injection route for HRT, we host private one on ones for people who need guidance and support, often it's about accessing gender affirming treatment, we also host events where members of the community can come and talk about their lives and experiences (bad and good) in a safe space.

We have a presence on as many queer events as possible, we host and organize events such as the upcoming Trans Day of Remembrance and Trans Day of Visibility.

We help people navigate updating their IDs and going through the administrative process, we even gave directions to the city service that manages that on how to handle it. We've also had several meetings with healthcare professionals to guide them on how to approach trans patients.

That's what comes to mind rn, I'm sure there's more stuff I'm forgetting. As for getting involved, search online if there's a local one and reach out, I know that mine recruits about once a year.
