Introduction to the Senior Enlisted Advisor to the Chairman of the Joint Chiefs of Staff

The position of Senior Enlisted Advisor to the Chairman of the Joint Chiefs of Staff (SEAC) was created in 2005 by Marine Corps Gen. Peter Pace, the Chairman at the time. This role serves as a direct link and spokesperson for all enlisted personnel across the Joint Force, providing advice on matters concerning total force integration, utilization, and readiness. Since its inception, six men have held this position, with the sixth and current SEAC, David L. Isom, assuming the role on June 20, 2025.

Role and Responsibilities of the SEAC

As the highest-ranking enlisted member of the United States Armed Forces, SEAC Isom connects the needs of approximately 2 million service members to the leadership that makes decisions for those who wear the nation’s uniform. According to Isom, his job is to provide “truthful, honest, critical advice and guidance on joint, combined, total force integration, enlisted development, health of the Joint Force, readiness of the Joint Force, and to serve as a direct linkage between the chairman and the Joint Force.” Isom ensures that the Joint Force knows they are represented and their perspectives are being brought to the table in meetings, whether on the Joint Staff or with the Department and in the office of the Secretary of War.

Importance of Fitness in the Military

Being in shape has always been crucial for Isom, and he emphasizes that fitness matters more now than ever. Isom recalls a time when he was featured in Muscle & Fitness in 1996, and today, he acknowledges that his career has seen more yesterdays than tomorrows. However, he still focuses on being in his best shape possible, even preparing to run in the annual Marine Corps Marathon later this year. Isom suggests that older adults, including those in service, should make fitness a part of their lifestyle and be willing to make up for missed workouts.

The U.S. military has been focusing on fitness, with initiatives like the Preservation of the Force and Family (POTFF) and Total Force Fitness. Isom is pleased with the progress made and believes that continuing to focus on the total human as a weapon system is essential. He encourages young Americans who want to serve their nation to start building healthy habits, eating right, and establishing a workout regime that balances strength training and cardio.
