Character references reflecting our founder’s professional reputation across defense, military, and academic communities.
Calvin consistently delivered under pressure on some of our most sensitive programs. His ability to translate complex cybersecurity risks into clear, actionable guidance for leadership was exceptional. He didn’t just identify vulnerabilities — he drove solutions from assessment through remediation. Any organization would benefit from his expertise and work ethic.
Working alongside Calvin on RMF compliance and system hardening, I saw firsthand how he elevated the entire team’s output. His documentation was immaculate, his STIG implementations were thorough, and he had a rare talent for communicating technical findings to non-technical stakeholders. A true professional who leads by example.
Chapple brought the same discipline and mission focus from his Army service directly into the cybersecurity field. In the intelligence community, attention to detail isn’t optional — it’s the difference between mission success and failure. Calvin operates at that level every day. I’d trust him with any classified operation without hesitation.
Calvin was among the top performers in our Cybersecurity Engineering program. His graduate research demonstrated both deep technical knowledge and a practical understanding of how cybersecurity integrates with real-world defense operations. His military background gave him a maturity and mission awareness that set him apart from his peers.
