Welcome to my Web site!

My name is Mark Rehorst.  Formerly an electrical engineer and now a dentist working at the Kenosh Community Health Center in Kenosha, Wisconsin.

I have worked at Motorola, Nippon Motorola, Avantek, Hewlett-Packard, Fujitsu Microelectronics, Stanford Microdevices, and Texas Instruments.

I have lived in Illinois, Wisconsin, Florida, Texas, California, Tokyo, Missouri, and Arizona.

My hobbies have included Kung Fu, a brief attempt to learn some Aikido, amateur radio, DIY audio, photography, scuba diving, antique radio and phonograph restoration, bicycling, and most recently I've been heavily involved in 3D printing.  Maybe someday I'll learn to fly a plane.

I like the music of Tom Waits, Morphine, Stevie Ray Vaughan, Jimi Hendrix, Radiohead, Morcheeba and a lot of others.
