On the back wall of SWT’s building is a commissioned painting by artist Daniel Bombardier. The mural, which overlooks a parking area used by a nearby hospital’s staff, was commissioned as a thank you to all the Front Line Health Care workers for their ongoing efforts in ensuring the best of care for their community.
