In the words of certified producers
“Athan and Marilyn have been the biggest mentors to us. They played a significant role in where we are today, and I owe a lot to them: to the work they have put in, and to their passion and their honesty.”

If you produce HP EVOO
We know your oil is more costly to make and the market doesn't always make it easier to find.
Small yield and higher cost, louder voices with no evidence, and oil that changes after bottling.
If you're looking for HP EVOO
You've been doing the reading. The claims are loud but too often the fine print is missing.
The most artistic labels can't show what's in the bottle, how it's been stored or how the phenolic potency protected.
We know that frustration.

Talk with Athan
Why High Phenolic Olive Oil Matters
Olive oil biophenols have been shown to support the protection of blood lipids from oxidative stress—when present at meaningful levels and used consistently.
But not all olive oils deliver these compounds in a reliable way.
Phenolic content can vary widely depending on harvest timing, production methods, storage conditions, and time.
Which means the value of an olive oil
is not just what is measured once—but what is preserved and delivered over time.
Consistency — not just concentration — determines
real health impact.
