Liz Chavez is an electrical engineer who spent a decade in robotics before an autoimmune diagnosis pushed her to question everything in her home. The surprise wasn’t the diagnosis itself — it was realizing how little she knew about the products she’d been using for years without a second thought.

She went looking for guidance and found two kinds of low-tox content: fear-based messaging that left her more anxious than informed, and influencer recommendations that expected her to take everything on faith. Neither worked for an engineer trained to evaluate evidence. So she built her own approach — and founded Casa de Chavez to share it.

She’s the creator of the CLEAR Method™ and STOP Method™, two frameworks that teach people how to evaluate product safety for themselves rather than depend on someone else’s recommendations. She writes for people just starting to question what’s in their homes — the moment right after something clicks and before the overwhelm sets in. 

Her approach is progress over perfection, data over dogma, and budget-realistic trade-offs over impossible standards. Her goal isn’t to build a following. It’s to put herself out of a job, one independent evaluator at a time.

What Liz speaks and writes about

  • Evaluating product safety using the CLEAR Method™ — the five-step framework for assessing any product (Composition, Labeling, Evidence, Alternatives, Risk).
  • Quick low-tox decisions in the store using the STOP Method™ — the three-minute framework for evaluating products on your phone while shopping.
  • Why “non-toxic” labels are mostly meaningless — and what to look for instead.
  • Endocrine disruptors, the research, and what the current evidence actually supports (and doesn’t).
  • How to teach low-tox evaluation to families without fear-based messaging.
  • Budget-realistic low-tox trade-offs — what to swap first, what to skip, and why “perfect low-tox” is a marketing fiction.
  • The engineer’s perspective on health communication — why evidence-forward beats expert-as-guru in the long run.
  • Greenwashing, ingredient transparency, and what manufacturers actually have to disclose (and what they don’t).

Liz Chavez is an electrical engineer turned low-tox educator. After an autoimmune diagnosis pushed her to question everything in her home, she founded Casa de Chavez to teach people how to evaluate product safety for themselves — progress over perfection, data over dogma. Creator of the CLEAR Method™ and STOP Method™.

Liz Chavez is an electrical engineer who spent a decade in robotics before an autoimmune diagnosis pushed her to question everything in her home. Unable to find low-tox guidance that was rigorous enough for an engineer and practical enough for a real family, she built her own — and founded Casa de Chavez to share it. 

She’s the creator of the CLEAR Method™ and STOP Method™, two frameworks for evaluating product safety. She writes for people just starting to question what’s in their homes and looking for where to begin — progress over perfection, data over dogma.
