Help out.

Slack by the Sea is a charity event supporting HOW Foundation of South Florida.

HOW Foundation Logo

HOW Foundation was formed with the purpose of bringing hyperbaric oxygen therapy to veterans suffering from traumatic brain injuries and post traumatic stress. 

HOW’s mission has grown to support student athletes, equestrians, and others. HOW also diligently advocates for this restorative treatment to be made widely available.
