A clinician who learned the business side

Doc Rob trained as a naturopathic physician and spent the next two decades inside the natural products industry, working the whole path from raw ingredient to retail shelf.

He has helped bring categories like probiotics, enzymes, whey protein, fermented foods, whole food supplements, and hemp-derived cannabinoids into the mainstream, advising founders on what to make, how to substantiate it, and how to talk about it without overpromising.

The through line is translation. Formulators, regulatory teams, marketers, buyers, and investors all describe the same product in different languages. Doc Rob speaks all five, which is usually what keeps a launch from stalling.

Product innovation, specifically

Most of the work starts in the same place: a company sees an opening in the market and needs to know whether the science, the supply chain, and the shopper all agree. Doc Rob helps answer that before the money is spent.

That includes sourcing and vetting ingredients, pressure-testing a concept against the evidence, and shaping the story the product will need on shelf and online.

The books

Two very different projects, both aimed at giving people enough context to make their own decisions.

A Healthier Ever After

Dr. Rob Streisfeld

Healthy living as a mindset rather than a diet. Borrowing a cast of characters from familiar stories, the book shows how repeated daily choices shape the health of a person, a family, and a community.
