About Greller and Company

Greller & Company was founded by Patrick Greller, a mechanical engineer who started out designing custom equipment for a variety of industries. His experience with window fabrication equipment led him to focus on developing the exclusive “no cutter stack” Sash Corner Cleaner. Greller & Company soon gained a reputation for quality machinery and innovative design. Our knowledgeable engineers are continually improving equipment design based on customer demand. With customer service as a top priority, the entire team at Greller & Company is committed to the success of those we serve.
