Redesigning Human and Animal Care Systems

Systems-Based Solutions for Obesity, Companion Animal Health, and Human Fertility Preservation

Redesigning Care Systems That Work—For Humans and Animals

We work with clinics, researchers, and mission-driven teams to redesign care systems at the intersection of health, ethics, and behavior. Our focus is on surfacing structural blind spots, reducing preventable error, and aligning systems with the lived experiences of those they serve.

Whether addressing:

  • Obesity and chronic disease in companion animals through a One Health lens

  • Fertility care redesign, rooted in ethical integrity and personal agency

  • Or veterinary and caregiving models where animals and humans are both vulnerable to systemic oversight

…our work brings clarity, compassion, and strategy to sectors too often governed by emotion rather than evidence-based behavior change.

About Erin

I’m a systems strategist and researcher working at the intersection of health, ethics, and behavior. My focus is on redesigning broken models of care—across fertility, veterinary medicine, and human-animal caregiving—to protect those most affected, prevent avoidable harm, and enable sustainable behavior change.

I use evidence, ethical analysis, and behavioral insight to uncover structural blind spots and improve decision-making across health and caregiving systems. Recent work includes research on obesity and chronic disease in companion animals through a One Health lens, and the redesign of the IVF egg retrieval process for ethical and logistical integrity—culminating in a personal retrieval at age 40, completed under strict medical and ethical constraints with the fewest possible animal-derived components.

I consult with clinics, researchers, and care-focused teams ready to evolve—those who want systems that do less harm, serve more truthfully, and reflect the realities others only model.
