Our Kennett Square and Greenville offices are following the current guidelines in place regarding closing/reopening. Most of our staff have been working from home since March and will continue to do so throughout the upcoming tax season.

We intend to continue to answer the phones, however, we may need to utilize the automated attendant from time to time. Calls to staff working from home will be forwarded to their cell phones. Please be considerate of the time you call as the forwarding cannot be turned off outside of working hours.

We are committed to practicing physical and social distancing.

Client appointments can be scheduled on a limited basis, and masks will be required. We continue to encourage client meetings by phone or video.

We will continue to utilize our secure online portal to exchange documents. We will also accept paper documents in our Delaware office during business hours or through the mail slot in the Kennett office.

Thank you,

Chad Fenstermacher
