Regularly Scheduled Appointments are seen daily with the exception of Admin Day on Tuesday Mornings.


Walk-in Patients are accepted every day with the exception of Admin Day on Tuesday Mornings.


Same-Day appointments must call in at 8:00 AM the same day they wish to be seen.


The last week of each month our following month schedule will become available for appointments.  Each day there are appointments called a "Same Day" appointment which means, the person wanting an appointment on that day can call at 8:00 am to possibly get one of these appointments.  We have one Walk-In Provider and one Urgent Care Provider on a daily basis.  We urge patients if you cannot make your appointment please call the clinic to cancel them.
