He finds the real problem, then builds what helps.

David Zatara is an engineer and data scientist in Flagstaff, Arizona. He started on drill sites, reading the ground one thin tube of soil at a time. Fifteen years later he works the same way: find the real problem, then build what helps. Today that means free websites for the questions his neighbors ask most.

Part 1 · Where it started

Fifteen years, three lessons

Each job taught him one habit he still uses on every project.

12011–2016 · Under the ground

A small sample speaks for a big place

An engineer pulls up one thin tube of soil and uses it to judge a whole hillside. A news number works the same way. A small count speaks for millions of people.

The lessonBefore you trust a number, ask who got counted and who got missed.

Do the job before you teach it

David never hired someone for a job he hadn't done himself. He did it, wrote the steps down, then handed them off. Over eleven years, that habit helped the agency consult for more than 100 clients.

The lessonGood instructions come from doing the work, not guessing at it.
32016–2024 · Operations work

Most mistakes happen in the handoff

At a phone company, every team did its job, yet work still went missing. The problem was never inside a team. It was in the space where one team passed work to the next.

The lessonTo fix a slow process, watch the handoffs, not the people.

Part 2 · The turn

Freely you received. Freely give.

For eleven years, Sherwood Digital built and marketed websites for healthcare professionals. In that time David watched nearly everything online turn into a subscription, even the sites people reach for in a hard moment: a prayer, a parenting answer, help after a diagnosis. Nobody should need a credit card to get in.

So the agency's skills became a gift. Sherwood Digital now builds and publishes for church congregations and community groups that have something worth sharing but can't afford to publish it. The work carries their name and costs them nothing.

Questions

Here are quick answers about David and his work.

Who is David Zatara?

David is an engineer who became a data scientist. He lives in Flagstaff, Arizona. He worked fifteen years in engineering, data and business, including eleven years running Sherwood Digital, a marketing agency for healthcare professionals in Orange County.

What does he build?

He builds free websites that answer the questions his neighbors ask about family, mental health, local help, learning and faith. One of them is Neighbor Radio, which gives plain, sourced answers about the faiths, cultures and holidays of the people next door.

Why is everything free?

Because of what he watched happen online. After years building and marketing websites, he saw nearly all of them turn into subscriptions, including the ones for faith and mental health, which people need most in the moment they can least afford a bill. So he builds sites that anyone can open and use right away, for free.

Where do the facts on Neighbor Radio come from?

They come from public sources such as the U.S. Census Bureau, Pew Research Center and the founding documents, and from the communities themselves. Every answer lists its sources at the bottom.
