About Sarah
Background
Sarah Miletich is Proof's CEO and the chemist behind every Proof formula. She trained in organic chemistry and cosmetic science, and her graduate capstone looked at how cannabis is absorbed through the skin, the science behind Proof's topicals.
She worked in medicine before moving into cannabis in 2017, and she brings that evidence-first approach to every product: refined cannabinoids for consistency from batch to batch, simple ingredients, and doses people can measure.
What Sarah does at Proof
- Formulates every Proof product, from the drops and capsules to the topicals.
- Leads the company as CEO.
- Co-hosts the Proof of Wellness podcast, launched in February 2026.
