Town Hall is open to the general public BY APPOINTMENT ONLY.  We are asking Town residents to continue to utilize our website, the mail and our newly installed drop box which is located immediately to the right of the front door of Town Hall.  If it is necessary for you to physically enter Town Hall please call ahead of time so we can better manage visitors and protect both residents and Town Hall employees.  

Thank you for your understanding.  We all welcome and hope for a return to some semblance of normalcy in the coming months and year ahead.  If there is anything we can do to assist you please do not hesitate to contact us.
