Inventing useful machines is my lifetime passion.  The entrepreneurial spirit goes deep in my family as they were almost all farmers, traders and merchants who immigrated to the United States and moved west as the country expanded in the 19th century. 

I grew up on my family’s farm in northwest Oklahoma in the 1980s.  Going to town was a luxury and I had plenty of time to think while driving a tractor in endless wide circles all day.  There is always problem to solve on the farm, and this is where I focused my energy.  I wanted to find ways to save myself time and effort doing menial tasks, so I started inventing and building devices to solve those problems.

My first experience with the US Patent and Trademark Office was in 1992.  I was spending a lot of time straightening radiator fins on our farm equipment so their engines would stay cool while running in the hot Oklahoma summer.  Starting with some nails and duct tape, I put together a device that would allow me to straighten five fins at a time, a five times improvement in speed!  Over the course of the school year this became my drafting project.  My drafting teacher, Bob Dowell, saw promise.  He helped me enter the USPTO Young Inventors and Creators Contest, where I was awarded a trip to Washington D.C. to present my invention and meet other inventors.  I was hooked!  I wanted to patent my inventions!

I pursued a degree in Biosystems and Agricultural Engineering at Oklahoma State University where I met Dr. Tim Bowser.  Tim Hired me to work in the newly constructed Food and Agricultural Products Research and Technology Center where I helped him design and build and innovative device that used a spring to grind meat while solving the problem of removing metal fragments.  Tim was granted a patent and I was listed as a co-inventor.  My first patent!

After graduation I was hired as a Security Engineer Officer for the US Department of State Bureau of Diplomatic Security.  This was a job very different than my degree training, but it was awesome!  I traveled to many countries, solving problems with technical equipment at our embassies and consulates.  I even had the honor of traveling with two of our Secretaries of State.  This experience really opened my perspective on the world.

After getting married, my wife and I decided to settle down and raise a family in Maryland.  Part of that was getting a job at Evapco, Inc., where I worked for the next 20 years, my last role being Product Development Director for Advanced Technology.  I honed my inventing and product development skills there, obtaining 49 patents worldwide.  One of the most important things that I learned at Evapco was how to design products for the customer.  Successful inventions must solve a real problem and be competitive in the marketplace.

my first invention

This is the second version of my radiator fin straightener from 1991.  I would later find out that a similar device was patented a few years earlier.
