About this app
The Volunteer Portal app is now available for existing volunteers! Volunteers can use the app to register for shifts, update contact information, submit hours, and other tasks typically managed by logging in online. Now, you can hold the power of the Volunteer Portal in the palm of your hand! The new mobile app will allow existing National Army Museum volunteers to become more engaged with the organization, helping enhance the overall volunteer experience. Note: This app is for Active Volunteers only at this time. Prospective Volunteers will not have access to the app until all training requirements have been completed. If you are not a registered volunteer and interested in becoming involved with the National Museum of the United States Army, please visit https://nmusa.volunteerportal.org today!
