Service

In February 2022, Sheriff Lemma was sworn in as the President of the Major County Sheriffs of America, a two-year term that he completed in February 2024, when he became the Immediate Past President. The Major County Sheriffs of America is a professional law enforcement association of the largest elected sheriffs’ offices dedicated to preserving the highest integrity in law enforcement. Additionally, Sheriff Lemma was appointed to serve as Secretary on the Board for the Florida Sheriffs Association, and will ascend to the role of Association President in July 2025. Sheriff Lemma serves on the board of directors for many non-profits that align with his personal and professional interests. In February 2021, Sheriff Lemma joined the Victoria’s Voice Foundation as a Board Member. Founded by David and Jackie Siegel of Westgate Reports, the foundation’s mission is to bring awareness and prevention of substance abuse, especially amongst teenagers, and was founded in memory of their daughter, Victoria, who died from a drug-related overdose. He is a founding board member of Project Opioid, an Orlando-based non-profit with multiple branches in Florida and now in California. He is also a board member directly, or through alternatives, of the Boys and Girls Club of Central Florida Seminole County Branches, Camaraderie Foundation, as well as Chairman of the Central Florida Intelligence Exchange (CFIX).

Education

He holds a Bachelors’ Degree in Criminal Justice Administration from Columbia College, a Masters’ Degree in Administrative Leadership from the University of Oklahoma and is a graduate of the Federal Bureau of Investigation National Academy in Quantico, Virginia. He also attended the Florida Department of Law Enforcement’s Chief Executive Institute in Tallahassee, Florida.

Career

Sheriff Lemma began his career with the Sheriff’s Office in 1992 as a Correctional Officer and was selected as a Deputy Sheriff four years later. He served as a School Resource Deputy and a Crimes Against Children Investigator before receiving a promotion to Sergeant of the Special Operations Section in 2002. Four years later, he was promoted to Lieutenant in the Community Services Division where he managed the agency’s crime prevention efforts, served as the Public Information Officer, and coordinated programs to assist the elderly and domestic violence victims.

Leadership

In 2008, Sheriff Lemma was promoted to Captain and tasked with management of the uniformed patrol division, property crime investigations, traffic safety and code enforcement. In 2011, he was appointed to Major of the Department of Neighborhood Policing. In this role, he oversaw the operation of five divisions including uniformed patrol, Special Operations, Juvenile Enforcement and Intervention, Public Affairs and Community Services. In 2014, he was appointed to Chief Deputy where he led operational and administrative functions for more than, at the time, 1,200 members of the Sheriff’s Office.
