A Message From RJ Lee Group Amid COVID-19:

Last night (March 19, 2020) Pennsylvania Governor Wolf issued an order for all non-life sustaining businesses in Pennsylvania to close. The order provides that “life sustaining business may remain open, but they must follow, at a minimum, the social distancing practices and other mitigation measures defined by the Centers for Disease Control to protect workers and patrons.”

According to guidance from the Commonwealth of Pennsylvania, RJ Lee Group is deemed a life sustaining business operation and will remain open.

Many of RJ Lee Group’s clients work in life sustaining industries. As such we will remain open and continue to serve our clients in the highest level possible, while keeping our workers and community safe.

We are taking the COVID-19 situation very seriously. We are ensuring that employees follow all Centers for Disease Control and Protection’s guidelines. We have taken precautions such as scheduling double shifts of staff, disinfecting all commonly used surfaces, and have hired a second shift cleaning crew to disinfect our building and workspaces.

At this critical time, everyone’s focus should be on fighting this pandemic. By maintaining our operation and continuing to provide our high level of technical support and customer service, we are committed to doing so.

We will continue to strive to maintain business operations that are safe during these uncertain times. Our goal is to serve our customers with the same level of care and expertise as our standards dictate, while maintaining a safe, clean, and productive operation.

At this time, all of our locations will remain open. You can reach out to us anytime by email or at 800.860.1775
