Mary C. Ferris, D.O.


Welcome adolescent, adult, and geriatric patients to my practice of family medicine.  I offer primary care services that include diagnosis and treatment of acute and chronic medical conditions; as well as gynecology, screening, and preventive care.

Experienced Medical Professionals

My practice offers a broad array of services geared to address today’s most common non-emergency illnesses and injuries. I know there is no such thing as a one-size-fits-all cure, so I never use a one-size-fits-all approach to your diagnosis. 

Coming Soon

When the office is closed, instead of a trip to an urgent care center, you may contact Dr. Ferris by using telemedicine technology.  This can be accomplished from the comfort of your own home.  

Secure internet telemedicine office visit encounters are appropriate for common ailments (sore throats to bladder infections) and not complex or chronic medical issues.  Just as with urgent care center visits, you may need follow-up appointments at the office.

There is an urgent care office visit charge for these encounters.  Some insurance companies do not pay for this type of service.  Minimal out-of-pocket fees vary from $50 to $100, depending on the length and complexity of service.  

For telemedicine appointments type this link into your browser:

Step by step directions:

1.)  Use a computer or device with camera/microphone.  (PC and Mac, Chrome/Firefox/Sarari compatible.  Android Chrome compatible.  IOS Safari compatible.)

2.)  Enter the web address noted above.

3.)  Allow your browser to use your webcam and microphone.

4.)  Type in your name and click "check in".  

5.)  When available, Dr. Ferris will start the visit.

Call tips:  Make sure you have a good internet connection.  Restart your device before the visit.  Test your camera and microphone from the "waiting room".
