Where Missions Meet Precision

Who We Are

Canis Major Nexus is more than a consulting firm, we’re a mission partner.

Registered in Texas and proudly recognized as a Woman-Owned, Service-Disabled Veteran-Owned, and Minority-Owned Small Business (WOSB, SDVOSB), we specialize in:

  • Cybersecurity & Compliance Readiness

  • Healthcare & Clinical Operations

  • Logistics & Supply Chain Enablement

  • Federal Go-to-Market Strategy

Our roots run deep in defense, healthcare, and IT. We’ve worn the uniform, delivered care to wounded warriors, managed federal supply chains, and designed compliance frameworks that withstand the toughest audits.

What does that mean for you?
We simplify complexity. We align innovation with regulation. And we deliver results that accelerate your mission.

Our Mission

To empower small businesses and federal partners with compliance, clarity, and strategy that accelerate mission success.

Because when innovation meets federal precision, barriers break, systems transform, and lives are impacted.
