Key Personnel Experience

Leadership With Real Federal Track Record

TallHouse was founded in May 2024 — but our leadership didn't start there. This reflects our CEO's direct, individual experience as key personnel, not a TallHouse corporate contract award.

U.S. Army · Information Assurance Support Services

Since 2024, TallHouse's CEO has served as key personnel supporting a performance-based Information Assurance Support Services contract for the U.S. Army — a multi-year effort valued at nearly $3M — leading RMF Steps 1–7 execution and ATO package assembly for a mission system.

In that role, he remediated 55 open POA&Ms and successfully migrated the system's control baseline to NIST SP 800-53 Revision 5 — the exact discipline TallHouse now brings to every subcontract and teaming engagement.
