Hi! I'm Jen.

I’m a Build Science Educator and Consultant. Through my company Practical Healthy Homes, I help families build healthy, resilient homes they can thrive in. I’m a triple-certified BBNC, BBEC, and EMRS Building Biologist, a certified Passive House Tradesperson, and a certified Permaculture Designer. The book I wrote, Destination Blue Sky, talks about how my husband and I healed our family from PANS, Mold and environmental illness, Lyme and co-infections, and cancer, by building a healthy home. I run the Facebook group Beyond Build Defects: Building a New Healthy Home. I serve on the Board of Directors for the Building Biology Institute of North America. I live in the California Sierra Foothills and work with clients worldwide.

FAQ

I know nothing about building. Will I understand this class?

This class was made for homeowners like you. No prior construction experience is required—just curiosity and a desire to make informed decisions.

I don’t have time!

That’s okay! The modules are designed to be listened to! Feel free to listen to the lectures while you're commuting, or chopping carrots, or loading the dishwasher, or going for a run.

Is this class relevant for my climate?

Yes! Every module explains how to adapt the concepts to your specific climate zone. You’ll also learn how to verify your zone and adjust construction details accordingly.

Can this help me work with my builder?

Absolutely. Knowing how the home should be built going in is the only way to make sure you end up with that at the end, and that's what this class will teach you.
