Our Story

When the pandemic hit, Dr. Eric Grutzner, MS, DDS, couldn’t get enough PPE gowns to keep his partners and his staff protected in their Minneapolis Endodontics practice. He tried to purchase a large supply of disposable gowns, which cost a fortune and was terrible for the environment. So he developed a gown and disinfection system that enabled the practice to have re-usable, hygienically clean gowns with every patient. The gowns are disinfected conveniently and locally in their office. The staff loved the new OverArmor system and he estimates it saved them over $100K a year in disposable gown costs.
