What I'm looking for

I'm looking to lead business-aligned cybersecurity and IT strategy, strengthen Zero Trust and regulatory compliance programs, manage enterprise risk, and build resilient teams and infrastructure in mission-critical environments.

At Griffiss Institute, I lead enterprise IT infrastructure, cybersecurity operations, and regulatory compliance across multi-site operations. I align technology strategy, multi-million-dollar budgets, and operational resilience with business objectives.

I led a flawless CMMC Level 2 C3PAO assessment, achieving 110/110 controls and a perfect SPRS score. I also architected a corporate-wide Zero Trust environment using Microsoft Intune, Cloud PKI, and automated SCEP certificate distribution.

Previously, I modernized Fortinet-based network infrastructure, led systems, networking, and helpdesk teams, and strengthened IT service management, SD-WAN connectivity, endpoint provisioning, and vendor operations. At PAR Government Systems, I delivered RMF compliance packages and Approval to Connect authorizations for defense platforms.

My background also includes global database and web operations, secure DevSecOps controls, classified-environment governance, and U.S. Army communications leadership. I bring MBA and MS education, CISSP and C-GRC certifications, and experience translating technical risk into executive and board-level action.
