A Message from the President

At Spectrum Holdings you’ll find a growth-oriented company with a true dedication to bringing together the latest engineering and technological solutions to make the world you live in safer and more secure.

In fact, you’ll find that over 75% of the work Spectrum Holdings subsidiaries are currently involved in is directly related to Homeland Security, as well as ending chemical warfare, biological warfare and the War on Terrorism—through entities like the Department of Homeland Security, the U.S. Army Corps of Engineers, the Department of Defense and the FAA.

From making sure our nation’s bombing training ranges are safe, to ensuring the air you breathe is free of biological contaminants, to seeing that the energy you need continues to flow, our subsidiaries are playing a key role in this ever-expanding arena.

Additionally, Spectrum offers capabilities that allow us to service a wide array of private-sector companies, with a client list that includes among many others Bechtel National, Inc., Microsoft, Louisiana State University, Disney Cruise Line, Esso Petroleum, Labatt Breweries and the Suffolk County Airport.

And each acquisition we make is designed to build a synergy in which each of the parts complements and strengthens the others. In fact, it is not uncommon for one division to call upon the resources of another for creative solutions, project management and manufacturing, to make sure that clients’ needs are fully met.

Finally, Spectrum Holdings is positioned for growth, ready to meet new emerging market opportunities through ongoing product diversification. Please take a few minutes now to review our companies and services. If you should have any questions, we encourage you to call us at 1-800-368-5278.
