Rich Arentzen met Tove Ohlander at the Orrefers Glass School in 1994. Soon after, we married, had children, and began a glass blowing studio in Norway. In 2007, we moved to Vermont and founded AO Glass, a combination of our two last names. 

At the time AO specialized in high-end sculptural vessels. However, to combat the recession, we began to make souvenir glass snowmen to sell as gifts. Vermont is a small community, and a connection through Senator Bernie Sanders brought the snowmen into the Smithsonian Museum gift store. 

In 2014, AO truly hit its stride and discovered the perfect niche; unfulfilled demand for glass manufacturing in the high-end lighting market. 

This journey has led AO Glass from a small, art glass studio, to a premiere vendor of glass components in the lighting industry. Our unique size enables us to provide clients with ample manufacturing capacity coupled with unmatched attentiveness to design and quality.
