Message from the Practice


McKnight Pediatrics Families,
We are continuing to see a rise in positive Covid cases. As we continue to deal with the rise, we are asking our families to please wear masks when they come to our facility. We are doing our best to prevent spread, protect our staff, as well as protect the most vulnerable of our patients, those who are too young to be vaccinated and those who are immunocompromised. We know that as a community we can take the small step of masking while in our office to protect everyone.

With Much Appreciation,
Marjorie B. McKnight, M. D.
