Although inconclusive, from a chronological standpoint, it appears that the first Chief of Police of Opelousas was Felix Chachere. However, it should be understood that, according to official records, on file with the Secretary of State's Office in Baton Rouge, La. the position's official title was "Marshal", and not Chief of Police. This issue notwithstanding, shows Felix Chachere holding the office from June 1934 until his demise in January 1941. On January 14, 1941, Roland Chachere was appointed to the post and remained "Marshal" until December 1942. On December 4, 1942, H.B. DeJean took over the reins. Roland Chachere regained the position in June 1946, and remained in office until he was defeated by Harold J. Doucet in June 1962. Roland Chachere was once again victorious in his bid for the post and, in July 1966, he once again became the city's chief law enforcement executive. In July 1970, Earl Guidroz was elected to the office and, from those records, provided by the Secretary of State's Office, was the last to be "officially" recognized as "Marshal". In August 1974, Howard Zerangue, Sr. was commissioned under the title of "Chief of Police", and held the position until 1980, when he was victorious in his bid for Sheriff of St. Landry Parish.

Percy Lalonde would become the next Chief of Police in September 1980. He was followed in office by Howard Zerangue, Jr., who made his bid for the office after having served as a member of the department's patrol division for several years. Then, in 1991, a historical event was realized.

The first African-American Chief of Police was elected, Larry J. Caillier. Chief Callier introduced an aggressive style of policing to address the large influx of illegal narcotics that plagued the streets of Opelousas in the early 90's. This style of policing made a significant impact in decreasing the amount of drugs plaguing the streets of Opelousas. Chief Callier retired as Chief of Police November 30, 2005.

On December 1, 2005 the Opelousas City Council appointed Assistant Chief Alexander T. Peck the position of Chief of Police to fill the remainder of the term of Larry J. Caillier. Alex Peck began his law enforcement career in July 1973, after graduating from LSU Law Enforcement Academy in Baton Rouge. He advanced from Patrolman First Class to Sergeant and in 1980 was promoted to Lieutenant. At that time he became Shift Supervisor of the Patrol Division. In 1996 he was promoted to captain and became Patrol Division Commander.

Presently, Perry Gallow serves as chief of police. Under his leadership many new programs such as Crime Suppression Team, state of the art communications equipment and leading edge surveillance techniques have been deployed and implemented.

Chief Gallow continues to provide his officers the training necessary to make them better at their profession in hopes of providing the highest level of service to the citizens and business community of Opelousas.
