Re-Starting PrEP through Magnet
Or, drop-in for services (first come, first serve).
To book a same-day drop-in appointment, grab a ticket from the ticket machine outside the building starting at 9:30 am each day, and come back at 10 am when we open. If you aren’t back at 10 am or if you lose your number, we will give your spot to the next person. Same-day appointments are generally between the hours of 10:30 am – 12:30 pm, but may also happen later in the afternoon. Getting a ticket does not guarantee there will be an appointment available on the same day.
