Dr. Louise Cason always had high hopes of becoming a doctor, even when it was ridiculous for a woman to be having that thought. After graduating with honors from Lakeland High School in Florida, she enrolled in the Florida State College for Women (FSCW), pursuing a degree in Chemistry. Dr. Cason worked in the dining hall in order to pay for her tuition. Her enthusiasm caught the eye of Dr. Jennie Tilt, a professor in Chemistry at FSCW, who mentored and encouraged her to go to medical school. While working toward her degree, Dr. Cason also did coursework at Baylor Medical College and the University of Houston, as arranged by Dr. Tilt. She received her Bachelor of Science degree in Chemistry in 1945.

When she applied to the University of Chicago, Dr. Tilt helped her receive a full scholarship. After graduating from medical school in 1950, she completed her residency in pediatrics from Duke University and training as chief resident from Jewish Hospital of Brooklyn (now the Interfaith Medical Center). Dr. Cason moved to south Florida and opened her own practice in Coconut Grove in 1953. She deliberately set up her practice in a mixed race area to challenge segregation and devoted many hours to her patients. Her specialty was pediatrics, but she was particularly interested in mental health as it relates to the child within the family unit.

Dr. Cason’s career in the medical field was quite extensive. She was with Variety Children's Hospital in Miami from its opening in the early 1950s. While there, she served as Chief of Pediatrics from 1958-1971 and President of the Medical Board from 1971-1974. She became Director of Ambulatory Services and Community Medicine at Variety Children's Hospital in 1981. When she became director, she had to give up her own practice. She headed a $50 million renovation project of the clinic and ambulatory service, which then became Miami Childrens Hospital. She retired from her position as director in 1988.

One of Dr. Cason’s many acknowledgements includes receiving the Elizabeth Blackwell Women in Medicine Award. In her spare time, she raised champion dalmatians.
