Information to make your first visit go smoothly
Welcome to eRiver Neurology. To simplify your first visit, you may download and print a registration packet. You can fill it out at home and then fax it to us at 845-452-9751 or bring the completed form with you on your initial visit.
Covid-19 is of greatest concern for transmission to the immune compromised and the elderly. To help reduce the risk of transmission we will offer Televisits.
Our staff will help you choose and setup the best application for you. The preferred apps are;
By Smart Phone:
By PC App:
Please call us for an appointment as you would normally do. Choose a provider and the appointment by TeleVisit will be set.
The visit will be a communication between you and the doctor. They will take your history, handle your questions, send prescriptions and order appropriate tests. They may also let you know if this is a situation that needs a live presence.
At the end of the call the doctor will check you out, complete their note and have the staff follow up with further appointments and the usual authorizations if needed.
We hope these measures will keep everyone safe and healthy during this difficult but hopefully brief period of inconvenience.
We provide outpatient infusions of medications for Multiple Sclerosis, Myasthenia Gravis and other Neurologic Diseases. This is done in a pleasant controlled setting minimizing person to person contact. Call for more information.
