“Technifex has had the pleasure of working with George Johnsen and Mammoth A/V for many years. Our projects almost always contain unique uses of imagery and audio content. It can be anything from a magic trick such as a Pepper’s Ghost effect to a choreographed LED chandelier with specially composed music and sound effects. It could be a dragon in a bottle, a painting the comes to life or a straight forward video presentation. You can be assured the best out-of-the-box thinking and problem solving capabilities available at any price from George and his company. I can’t imagine going anywhere else.”

Rock Hall | Chairman, Technifex Inc.

“George and Maggie are two of the most incredible people in Hollywood. They are professional and extraordinarily talented and, most of all, two of the kindest people we have ever worked with. The MammothVision team will deliver the best product, at the best price, and on schedule as promised. If only everyone in the entertainment industry could be like them.”

Mark Kalbfleisch & Joseph Girouard | DLK Brand Consulting LLC, Las Vegas, NV.

“As Vice President of Entertainment for Princess Cruises, I had the pleasure of working with George Johnsen and Mammoth Vision on Stephen Schwartz’s “Magic To Do.” This ground breaking show set a new standard for original cruise ship productions and went on to win both a Magellan Award and the Live Design Excellence Award for theatre production. George’s beautiful work was integral to the success of the show.”

Adrian Fischer | Vice President of Entertainment, Princess Cruises.

“Mammoth is about problem solving with an intense focus on the quality of the product and not the ego behind it. It’s incredibly refreshing to know a fellow collaborator has your back, has the best interest of the project at heart, and can deliver incredible product on-time and on-budget.”

Alex M. Calle | Chief Creative Officer & Chief Executive Officer, Entertainment Design Corporation.

“Quite simply the only choice that can complete our projects. Always delivers more than we pay for.”

Steve Fox | CEO, Rockdome Inc.

“Over the many years we have worked together I have come to depend on MammothVision as our go to problem solver for anything media., Whether it is system design, show production, or just new ideas, they are the easiest call I ever have to make.”
