I collaborated with DoD sponsors such as MDA, DSS, and DISA to ensure full compliance with Risk Management Framework (RMF) security requirements, ensuring a secure operating environment for mission-critical systems.I also spearheaded the development of a framework that integrated automation and orchestration tools with repeatable processes to efficiently apply DISA STIGs (Security Technical Implementation Guides) across both Windows and Linux-based HPC environments, significantly enhancing security and compliance.Key Achievements:Led the design and deployment of secure HPC systems in one of the largest DoD environments, managing over 10,000 CPU and GPU resources.Directed a cross-functional team of 50+ engineers to optimize and secure complex, high-density computing systems.Ensured compliance with RMF and DISA STIG security protocols in collaboration with DoD sponsors.Developed and implemented automation and orchestration tools to streamline security and operational processes.

As VP CIO/CISO at Iron Bow Technologies, I led IT and cybersecurity transformation during a period of rapid growth, acquisitions, and rebranding. I successfully implemented an integrated ERP, CRM, HCM, and business intelligence platform on Oracle EBS, replacing legacy systems. This initiative streamlined operations, provided real-time data insights, and supported business growth by integrating sales, HR, and business analytics functions.In my role as CISO, I enhanced Iron Bow’s cybersecurity posture by implementing advanced security protocols such as network segmentation, encryption, and endpoint protection, significantly reducing risk and ensuring compliance with industry standards.I also developed the infrastructure for Iron Bow Service Select, offering clients cloud-based IT services through a consumption-based model. This allowed clients to seamlessly transition from on-premise to cloud environments, improving operational flexibility and cost predictability.Key Achievements:ERP Transformation: Led the migration to Oracle EBS, integrating ERP, CRM, HCM, and business intelligence, enhancing operational efficiency and decision-making.Cybersecurity Leadership: Strengthened cybersecurity protocols, reducing risks and ensuring regulatory compliance.Growth & M&A Integration: Supported company expansion through strategic IT alignment during acquisitions and rebranding.Cloud-Based Services: Launched Iron Bow Service Select, delivering managed IT services and cloud solutions, enabling clients to reduce costs and improve efficiency.

As Chief Information Security Engineer, I led the design and implementation of the Lab's information security strategy, focusing on risk management, operational improvements, and compliance. I developed a risk assessment framework to prioritize critical assets, assess potential threats, and evaluate attack vectors. I managed daily Infosec operations, including incident response, forensics, and new technology assessments, while collaborating with DoD sponsors (NCIS, JTF-GNO, DISA, NSA) on security initiatives.I also led the effort to achieve FISMA compliance by implementing NIST 800-53 security controls, ensuring federal security standards were met.Key Achievements:Security Metrics Program: Created a comprehensive security metrics program, focusing on configuration management, Infosec projects, operations, and technology, which became the foundation for Infosec operations.Application Whitelisting: Implemented Bit9 across 8,500 systems, significantly enhancing protection against advanced persistent threats.Infrastructure Review: Conducted a detailed security review, identifying and remediating vulnerabilities through multiple security projects.Risk Assessment & Prioritization: Led cross-department teams in developing a risk assessment methodology to prioritize critical Infosec projects.FISMA Compliance: Successfully implemented NIST 800-53 controls, achieving full FISMA compliance.

At Kennametal, I led the transformation of the global IT infrastructure across 170 locations in 60 countries. My work focused on aligning IT with corporate strategy by evaluating the existing infrastructure—comprising Cisco networking, HP servers, and EMC SAN architecture—and implementing improvements to enhance efficiency and scalability. I collaborated with internal IT, consultants, and business units to standardize services and modernize technologies.I introduced new technologies such as collaboration portals, WAN accelerators, and unified messaging, while consolidating and standardizing global DNS/DHCP services and revamping the Lotus Domino/Quickr email systems. My role included mentoring IT staff, developing a three-year infrastructure roadmap, and designing a CMDB to improve asset tracking, change management, and helpdesk operations.Key Achievements:Developed a multi-tiered EMC SAN storage architecture to support Unix, Linux, and Windows applications.Created a three-year infrastructure roadmap, laying the foundation for future IT growth and alignment with business goals.Utilized Six Sigma QFD methodology to validate and ensure alignment of IT projects with business needs.Streamlined IT processes and improved integration activities for mergers and acquisitions.Enhanced global communication between IT and business units, promoting alignment through strategic marketing of the IT roadmap.

As Director of Information Technology at IDA, I managed a 65-member technical team providing enterprise IT support for three R&D centers that served the Office of the Secretary of Defense and the Joint Staff on national security issues. I led initiatives to improve the technology architecture, including client, server, storage, application, and network environments. I collaborated with ISPs on designing SLAs, and implemented cutting-edge technologies such as SAN, VPN, VoIP, and web-based applications to enhance operational efficiency and scalability.I was responsible for evaluating new technology requirements, providing strategic recommendations to executive leadership, and ensuring all IT projects were completed within scope, budget, and schedule. Additionally, I worked closely with Information Security specialists from DSS and DHS to maintain compliance with the NISPOM, safeguarding both new and existing facilities.Key Achievements:Service Desk Transformation: Transitioned the traditional helpdesk into an enterprise-wide service desk, integrating IT, HR, finance, and physical security requests, underpinned by a CMDB for incident, problem, change, and asset management.VoIP Migration: Led the migration to a secure Cisco VoIP architecture, beginning with smaller remote sites to build internal competencies before upgrading the primary PBX system.Business Continuity Planning: Designed and implemented a business continuity and disaster recovery plan, ensuring operational resilience and preparedness for potential disruptions.Information Security Enhancement: Strengthened security posture by implementing intrusion prevention systems, security event management, enterprise-wide patch management, and a robust security metrics process.
