I'm a retired firefighter/EMT with national certification as a fire and explosion investigator. I retired from the fire service at the rank of Fire Investigator in November 2005. I have also been employed in private security, in the alarm industry, as an airport police officer, as a 911 dispatcher, and as a contract engineer in radio broadcasting.

From 1995 to 2006 I served as an intermittent employee of the National Disaster Medical System, part of the US Public Health Service in association with FEMA. I was a founding member of the Denver based Disaster Medical Assistance Team (team CO-2) which has a double designation as the Central US National Medical Response Team for Weapons of Mass Destruction (NMRT). As a member of the Management Support Team I responded to many federal deployments including the Summer Olympics in Atlanta (1996), the GS-8 Summit in Denver (1997), Hurricane Georges in the US Virgin Islands, Puerto Rico and Florida (1998), Operation Provide Refuge at Fort Dix NJ (1999), and Hurricanes Katrina and Rita in New Orleans (2005/2006).

In 2003 I was recognized as a Founding Member of the US Department of Homeland Security.

I am a published author and a freelance photographer. I publish some of my photos on my Flickr site which is www.flickr.com/photos/antennawizard/. In 1998 I published a book about AM broadcast station antenna systems. I have also written 17 magazine articles including an article about the Denver area light rail transportation system published in the July 2011 issue of Trains magazine.

I am a licensed General class amateur radio (ham) operator. My call sign is N0NNK. I have been licensed since 1991.

I was an extra in the 1997 movie Asteroid. I played a firefighter.

I presently live in Rockford Illinois not far from the hospital in which I was born (Swedish American). I lived in the Denver, Colorado area for 30 years. I returned to Rockford after I retired from the fire service.
