Did you know that our counselors are often up for meeting outside?  If the idea of having a session in an office indoors is not appealing to you, let you counselor know and a 'walk and talk' can be scheduled.  If you like to be indoors, that's cool too!  We are pretty fond of our office space, located on the Pavilion side of the Health Center.  You'll see the wicker furniture on the porch.  We have a waiting room right through that door.
If you do not see a time that works for you with any of our WWC counselors, please consider utilizing Timely Care, our free telehealth service. they have counselors available 24/7! Another feature of Timely Care is the ability to select providers based on specialty and identity.  Students are able to take advantage of Timely Care over breaks as well as during the school year.
