Information from Koike on the Coronavirus (COVID-19)

The coronavirus (COVID-19) situation remains extremely fluid and rapidly changing, affecting people and companies worldwide. As we find ourselves navigating through extremely challenging circumstances, we would like to update you on our company.    

You may know that New York State has ordered non-essential business to close.  Our business does support essential industries and we are able to remain open.  However, NYS is experiencing the highest number of outbreaks in the US, for the safety and health of our employees and community; we are keeping as many as possible home.  Those in our building will follow CDC guidelines to remain safe.

Sales, Service and Engineering are fully functional working from their homes and ready to respond to your inquiries and keep projects moving forward.  Extensions have been transferred, just use your regular means to contact us.  These are ever changing times.  Koike will continue to adapt and adjust to meet these challenging times and provide the best service possible to our customers. 

We are here, open and ready to answer your questions.

We hope you and your families stay safe and healthy.
