Walk-in Hours

Note: Please call our office first before coming in if you are ill and need to be seen to avoid the potential of unnecessarily exposing other patients and our staff to the novel coronavirus. Please be advised that we have temporarily suspended our walk-in hours until further notice. You must call for an appointment if you need to be seen so we can adequately assist you. This does not mean that we won’t see you, but we are asking for your cooperation in calling first to ensure that proper infection control and precautions are carried out. Thank you for understanding.

Telemedicine is a great alternative to coming into the office. It allows your practitioner at our office to see you face-to-face while you remain safely at home. The process is simple. You don’t need any apps, software, or accounts. All you need is a smartphone, tablet, or computer, and a reliable connection (wi-fi or cellular). Just click the link we send to you and, when prompted, enable your camera and microphone. Due to these challenging times with the COVID crisis, there’s no fee for your telehealth visit for the vast majority of patients, and your visit is documented in your medical record. Make sure to call our office for any routine visit or problem you may have so we can maintain your continuity of care. We don’t know exactly when this crisis will end, so we want to be sure you receive the care you need now.
