ACC-RSA is proud to congratulate Dr. Summer Wilson on graduating from the Senior Service College Fellowship at the Warfighting Acquisition University located at Fort Belvoir, Virginia.

Dr. Wilson’s accomplishment marks an important milestone for ACC-RSA, as she becomes the fourth consecutive employee in the past four years to successfully complete this prestigious program. Her achievement reflects not only her dedication and professionalism, but also ACC-RSA’s continued commitment to developing future leaders across the workforce.

Following completion of the fellowship, Dr. Wilson will begin a broadening developmental assignment at Fort Belvoir, where she will serve as the incoming Acting Business Management Director for the Program Management Office, Formation Based Mission Autonomy, under CPE Mission Autonomy.

Please join us in congratulating Dr. Wilson on this outstanding achievement and wishing her continued success in her future endeavors.

Today, on Memorial Day, we honor and remember the brave men and women who gave their lives in service to our nation. Their courage, sacrifice and unwavering commitment to defending our freedoms will never be forgotten.

As we reflect on the meaning of this day, ACC-RSA joins the nation in paying tribute to our fallen heroes and the families, friends and fellow service members who carry their legacy forward.

This Memorial Day weekend, as we honor the service and sacrifice of those we have lost, ACC-RSA also pauses to remember and honor our teammate and friend, Mr. Timothy Jerome Griffin.

Mr. Griffin served as a team lead within the Modernization Directorate and was a valued member of the ACC-RSA team. His professionalism, dedication and impact on those around him will not be forgotten.

We extend our deepest condolences to his family, friends and colleagues during this difficult time.

May is Mental Health Awareness Month. Unlike other organizations, Soldiers in the Army work and live together in an environment that encourages and thrives on teamwork to accomplish missions. This close-knit work environment provides an opportunity for Soldiers to get to know one another on more personal levels and knowing that support and communication is open at all times, is a key player in making a difference.

Jeffrey Caldwell, acting executive director, and Col. Chris Thomas, acting deputy director, represented ACC-RSA during today’s Alabama Update at the Von Braun Center, where Gov. Kay Ivey highlighted economic growth, infrastructure investment and workforce development across the state.

During her remarks, Ivey pointed to continued expansion in North Alabama, including growth tied to aerospace, defense and technology industries in the Huntsville area. She also highlighted ongoing investments in education, broadband connectivity, transportation infrastructure and public safety.

The governor noted Alabama has generated billions in economic investment supporting approximately 100,000 jobs statewide, while also emphasizing projects connected to Rebuild Alabama, including continued improvements to I-565 and other transportation corridors.

Ivey also discussed Alabama’s record education budget and efforts to improve literacy and math performance statewide to strengthen the future workforce.

For ACC-RSA teammates who live and work throughout Huntsville, Madison and the Tennessee Valley, the discussion reinforced the connection between Alabama’s continued growth and the defense mission supported across Redstone Arsenal.

Special thanks to the Huntsville/Madison County Chamber for hosting today’s luncheon and bringing together leaders from across government, industry and the community.
