Sandi had worked as a music teacher for 18 years. Then, life took an unexpected turn when she was diagnosed with a neurological condition caused by an abnormality in the shape of her skull. She needed life-saving brain surgery. After surgery, however, Sandi was no longer able to teach and was forced to set her sights on a new career. That's about the time when she was introduced to Salesforce. Since then, Salesforce has become one of Sandi's biggest passions and, with the support of both the Trailblazer Community and Trailhead by her side, Sandi quickly became a Salesforce Admin — and is now 4x certified.
