Our Founder

Dan Ferlic was a Registered Technologist for over 40 years and employed by 3M Company in the X-ray Imaging Division. More than thirty years ago he created the 3M Ferlic Filter for Chest Radiography. This filter had widespread use in both the United States and Europe.

Seeing the need for high quality cassette covers to help technologists and improve infection control, Dan designed the SLIDER-er x-ray cassette covers. Now, 25 years later, the SLIDER-er covers are an industry standard and used by hospitals all across the United States.
