Thor Lundgren is an Emergency Room nurse at All Saints Hospital. He is played by Stephen Wallem.
He is dedicated to his job and is always there for Jackie when she needs him. He is quick to comment and quite humorous. He lives with Type 1 Diabetes. He also has a self-confessed "wedding cake addiction", which likely contributes to his diabetes. It is later revealed that Thor has had an eye removed due to his diabetes, as Jackie holds something for him near the side of his face, but realizes he cannot see it.
He wore adult braces for three years, is a musical enthusiast but also has the voice of an angel.
When Zoey held a nurses appreciation lunch, he was the only other nurse who attended.
