As we monitor and learn more about the spread of Coronavirus in our communities, we want to be transparent about what we’re doing as a company to protect our customers and employees.

Protecting Our Employees and Customers

As our employees interact with customers and the general public, we have taken steps to limit exposure to the virus. We have put restrictions on travel, are postponing large-scale events, limiting the size of meetings, providing remote-work solutions, and continue to reinforce safe behavior in every environment – from customer homes and businesses to our office, where we have ramped up deep-cleaning. We are partnering with manufacturers to source as many sanitizers and protective supplies as possible and are prioritizing distribution to our employees. They will sanitize their hands and will be wearing personal protective equipment when interacting with customers; including masks, gloves, and shoe covers. Additionally, we have protocols in place that activate closures, disinfection and appropriate quarantine procedures based on recommendations by government and health agencies.

Assisting Our Employees

We are in continuous communication with our employees reminding them about the importance of good hygiene, providing them with health education and support whenever needed. Employees who feel ill have been told to not report to work and we have specific quarantine and communication procedures in place should an employee be diagnosed with COVID-19 or is asked to self-isolate by a public health authority, and to provide comprehensive benefits to support them.

What We Ask of You

We are taking every precaution to ensure the safety and health of our communities, but we need your help. If you are experiencing flu-like symptoms and have a scheduled appointment, please let our office professionals know so that we can discuss options with you to ensure our collective well-being.

We truly appreciate your cooperation and understanding!
