Our Story

When you need something built that has never been constructed before, Entech Innovative Engineering finds a way to execute it. From the intricate complexity of the display mechanism for the Smithsonian’s Hope Diamond to the magnificent grandeur of Walt Disney Company’s Cinderella Castle 50th Anniversary Iconic Regalia, Entech can make anything! Creating the dynamic, captivating, compelling, educational and innovative for the industries we serve is our passion and focus at Entech Innovative.


After two decades of accomplishment, our award-winning work is installed worldwide and our reputation for leading innovation in our industry continues to grow.

From Humble Beginnings

Founder John Marhoefer chose the challenge of starting his own company on the principles learned as a young engineer of sound structural and mechanical design, cost-effective problem solving and on the basis of customer commitment. From our humble beginnings in a mother-in-law suite over a garage to our 30,000 square foot office and fabrication facility of today, Entech Innovative has grown in response to the needs of our varied clients. To meet our clients’ needs, we approach each project with a combination of creativity and practicality to create design solutions that deliver the client’s vision while making engineering and financial sense.


One early example is a project we, as a small young company, created for the Universal Studios Hollywood Flintstones Stage Show. The Pterodactyl Airline, a truly complex element, “flew” over the audience carrying performers, making the quality and durability of the design and construction essential to public safety during performances. At the same time, the creative representation had to be believable within the story of the show.


After convincing the visiting project executives we had the resources to take on the job, John and the team got together and built what proved to be the first in a long line of what Entech Innovative would come to specialize in: complex, engineered, iconic elements other companies avoid or are not sure how to create.

To A Reputation For Leading Innovation

Since then, Entech Innovative has helped scores of clients realize their visions; helping them navigate the design build process, developing innovative solutions to fabrication and engineering problems, suggesting alternatives to established processes when it makes sense for the success of the project and always seeking the challenge of the project we have not done before. In each case, Entech Innovative uses our rare combination of innovative insight and no-nonsense solution sense to develop an end result that exceeds the expectations of an impressive client list which includes Disney, Universal Studios, FAO Schwarz, Ford, Hard Rock and The Smithsonian Institution.
