Bonnie was born in Erath, La. She graduated from Erath High School in 1961. Bonnie attended UL (SLI at the time) and graduated with a BS in French-Science education. She then taught at Delcambre and Erath High Schools for 15 years beginning in 1964. In 1979, she went to work for the Vermilion Parish Mosquito Control program as Biologist under the directorship of Sam Riché. Bonnie succeeded Sam as director and eventually retired in 2001.
Bonnie was very active in the LMCA and served on the Board of Directors for many years and was its President in 1987. She also served on numerous committees. The accomplishments of which she is most proud are the establishment of encephalitis surveillance in her district, and the creation of the alert Encephalitis Alert System during a time when each mosquito abatement program was doing its own surveillance. She coordinated the surveillance results from each program and sent out notifications to all participating districts via fax. This allowed the districts to have a better overall picture of what disease activity was going on throughout the state.
Bonnie Broussard received the Hathaway-Ritter Distinguished Achievement Award in 2001.
