About US
generational leap in construction science
No single commercial product currently surpasses our Sentry Shield system across all key metrics (self-healing, fire/water/mold-proof, wind/structural performance, EMP/IEMI shielding, net-zero integration, and cost-effectiveness).
Our combination of self-healing MUF microcapsules in MgO matrix + hybrid reclaimed steel framing + optional Stealth S3X is among the most advanced available today.
About Sentry Shield Structural technology
Our Mission
Our Story
Founded by Anita Siegel, Sentry Shield was born from a deep commitment to solve real problems: the affordable housing crisis, the need for resilient infrastructure, and the urgent requirement to better support disabled adults and military veterans.
After we successfully designed and delivered a modular home that met stringent new Tyndall Air Force Base standards — when no one else could — the couple realized they could do far more. Combining her manufacturing expertise and military connections with her vision, she created a full suite of advanced materials and housing solutions.
Every product we build directly supports Sophia’s Place, our Florida 501(c)(3) nonprofit sanctuary for disabled adults and military veterans in Lake Nona. Profits from Sentry Shield help fund housing, wellness services, vocational training, and long-term care for those who need it most.
What Makes Us Different
We don’t just build homes — we engineer smarter, stronger materials:
- Self-Healing Sentry MgO Boards — Advanced magnesium oxide composites with embedded microcapsules that automatically repair cracks and damage.
- S3X Protective Coatings — Revolutionary hydrophobic, weather-resistant, and mold-preventing coatings that keep structures drier and longer-lasting.
- Rapid-Deploy Modular Systems — 6-inch reclaimed structural steel frames combined with Sentry Shield materials allow complete structures to be erected in hours, not months.
- Net-Zero Ready — Designed for seamless integration with Tesla solar and energy systems.
Our products are fireproof, waterproof, mold-resistant, impact-resistant, and built for Florida’s harsh climate — and beyond.
Our Veteran Commitment
We proudly award **1000 dealerships at no cost** to qualified disabled and transitioning veterans. No franchise fees. Full training and support.
