To join the Silver Spring Chapter of PMI (or any PMI chapter), you must also be a member of PMI.
If you wish to join the Silver Sping Chapter, click here. When you proceed to checkout, you will be asked for your PMI username and password (if you are not already logged on). If you do not have a username or password, you can create an account at that point in order to be able to log on to the system and join the chapter (and PMI, if you are not already a member).
Yearly dues for Silver Spring Chapter are $20.
