Clinic Hours

STD clinics are held weekly at the Government Services Center on the following days:

  • Wednesday - noon-6pm
  • Thursdays - 9am-noon

Since our services are offered on a walk-in basis we may need to close early if capacity is reached.

To prepare for your visit:

  • Please arrive 30 minutes before our posted closing time.
  • It is helpful if you eat a meal and drink plenty of fluids before your visit.

If you are coming in for treatment, please bring your or your partner’s positive test results.  We cannot treat you without those results, which we may not have access to.  

All clinics will be closed on official holidays. Visit our Clinic & Events Calendar for the full schedule.

The Chester County Health Department also offers outreach and education programs for schools and the general public. Email for more information.
