Halle travelled to Dublin, Ireland to complete her medical degree and graduated from the Royal College of Surgeons in Ireland in May 2021. With her unique background Halle loves explaining the intersection between art and medicine and hopes to continue this exploration throughout her career. She is a lifelong athlete and loves all things sports! She played soccer, ice hockey and lacrosse competitively growing up and then rugby in college and Gaelic football while attending medical school. Even though she is a city girl, she loves being outdoors and exploring what this amazing planet has to offer.
