I ask questions, especially why. I’m an engineer who loves ideas, tools, & creative problem solving. I’m a technology geek - especially for everything Internet. I can explain difficult subjects with simple words and insightful demonstrations. I can tell stories , make anything, and convince people to take action. I have integrity and lead by example. Most of all, I care.


  • Analyzing - how does this work, why?
  • Convincing - strategy, stories, proof points, engaging experiences
  • Engineering - finding & fixing problems (see my favorite quote)
  • Explaining - teaching, writing, digital media, simplifying, presenting, demos
  • Innovating - creativity, ideas, concepts, trends, opportunities, “what if"
  • Internet - telecom, networks, computers, software, architecture
  • Making - mechanical, prototypes, audio, video, software, websites, fixing, manufacturing
  • Questions - conversations, interviews, uncovering, paraphrasing

Who am I?

Have you ever been asked to tell a story or two about yourself?

People like to understand who you are and what you've done. Here's four stories that describe some real turning points in my life.

Machinist to ME

Rebuilding an Opel Cadet engine

“It’s hard to believe Jeff did that.”

“Did what?” I replied.

It was 1975 and I had just started at Iowa State. Reb’s mom and I were were standing by the fence, watching Saydel High School play their first home football game of the season.

“You didn’t know … Jeff committed suicide.”

Reb, Jeff, and I had graduated the year before in ’74. With my parents divorced and me out on my own, it looked like my life after graduation was destined to be working at a machine shop. Jeff – my best friend since Cornell Elementary – convinced me otherwise.

Building the dome home

Dome home in Sherrill, Iowa

“Engineering is the art of making what you want from things you can get.” – Jerry Avins

Shortly after I graduated in Mechanical Engineering from Iowa State, I told my friend Jim Mackey “Cindy and I are going to build a geodesic dome home.” “Figures,” he said. “Foster, you living in a regular house would be like like an architect living in a mobile home.”

I was reading The Dome Builder’s Handbook by John Prenis at the time and thought “Cool, let’s build one.” Thing is, I’d never built a regular house. Heck, I was a machinist, not a carpenter. Granddad was the carpenter. I kept thinking “Maybe it runs in the family.”

So in September 1980 my wife and I started building our first home: a round house surrounded by cornfields outside Sherrill, Iowa.

Who I am?

Doug signatureDiscovering who you are can be really tough.

For me it happened when I was unemployed and had to (re)write my resume.

Bob was a good friend of mine and the VP of HR for a big six accounting firm. I thought he could give me some tips on how to make my resume better. He took it, looked at it, then handed it back to me. He said “Who is this?” I said, “Not funny, it’s me! “No it’s not,” he said, “I don’t see you in this piece of paper. Go try it again.”

I was crushed, but I learned a good lesson. Since then I’ve read thousands of resumes and hired hundreds of people. While this version reflects who I am, what I’ve done, and what I can do ... I think you'll learn more about me by reading the backstory.

180,000 Cisco IP Phones in 10 minutes

Cisco 7960 IP phone

Walk into Bank of America and you’ll see Cisco IP telephones. Lots of them. Want to know how they got there?

Let me tell you my best sales story.

The first time I saw voice and video work over a data network was at our Cisco sales lab in Raleigh. My boss Matt Mullady was standing beside me, watching a demo, shaking his head: “This is amazing. This is going to change everything.”

If you're looking for me on social media, you can find me as theIdeaMechanic.

So what's up with the name?

Well, the first word - idea - seems to fit me. I never run out of ideas.

And the second word - mechanic - that fits me too. There’s not much that I can’t make or fix.
