Founder Biography
Christopher L. Penn — Founder & CEO
Christopher L. Penn is a U.S. military veteran and the founder of Mr Hemp House™, a veteran-owned healthy home company specializing in GaiaCrete® hempcrete insulation and non-toxic building materials.
After witnessing the health impacts of toxic building materials on fellow veterans and their families, Penn founded Mr Hemp House in 2019 with a singular mission: "Healthy Homes for All." His company has since grown to serve all 50 states with professional hemp insulation installation, in-home Home Health Score, and a suite of digital tools including the Home Health Score app.
Penn developed GaiaCrete® — a proprietary hempcrete alternative enhanced with misc pozzolans and more — as a superior, more accessible version of traditional hempcrete for the American market. The material is carbon-negative, naturally fire-resistant (4+ hour rating), mold-resistant by design when properly installed, and has a 100+ year lifespan.
Under Penn's leadership, Mr Hemp House has expanded into a comprehensive healthy home ecosystem including MHH University™ (education and certification), MrEcoHome™ (eco-friendly products marketplace), and AI-powered tools like HempBuild Global Pro™ and The Poisoned Home™ AI.
Penn is available for interviews on topics including: hemp building science, indoor air quality and health, veteran entrepreneurship, sustainable construction, mold prevention, and the future of carbon-negative building materials.
Brand Story
Mr Hemp House™ was born from a veteran's commitment to protecting American families from the hidden dangers in their own homes. The average American home contains over 400 potentially toxic chemicals in its building materials — from formaldehyde in insulation to isocyanates in spray foam.
Mr Hemp House offers a complete alternative: GaiaCrete® hempcrete insulation that is non-toxic, carbon-negative, naturally fire-resistant, and mold-resistant by design when properly installed. The company's Home Health Score program identifies toxins in existing homes and provides actionable remediation plans.
The company's mission — "Healthy Homes for All" — drives everything from product development to education. Through MHH University, the company trains the next generation of hemp builders. Through the Home Health Score app, it makes home health evaluation accessible to every family in America.
