Message from the Practice


McKnight Pediatrics continues to try to do its part in helping to contain this virus and "flatten the curve". Everything we know tells us the only way to do that is encourage our citizens to stay home, only going out for necessities. In order to comply with these recommendations, keep our families and staff safe, and provide the necessary well and sick care for our patients we have implemented the following changes as of Monday March 30th, 2020.

We will see well children who are newborns, 2 months, 4 months, 6 months, 12 months, 15 months and 4 years old M-F in the mornings. We chose these ages for in office visits because it is at these ages that children are due for important immunizations.
We will have virtual visits for all other ages as needed. Please still complete and submit your ASQ3 development screen as usual prior to your appointment. As soon as we are able, we will get your child in for vital signs, hearing and vision exams.
Sick appointments will be scheduled starting late morning/early afternoon Mon-Fri. When possible we will do virtual visits for sick patients.
We will schedule less patients each hour to minimize any time spent in the waiting room.

McKnight Pediatrics monitors the changes occurring and policy recommendations being made on a daily basis. We will make changes accordingly. It is our hope that we will return to life as usual sooner rather than later. Reality and data tell us we must all take this pandemic seriously and do our part.

Please do not hesitate to call us if you have questions. Stay tuned for updates.

On a lighter note, we hope everyone is finding very creative ways to spend all of this extra time with family. One exercise for our children might be to think about, write or draw a picture about something that makes them happy. The adults might want to do the same. On my list is gratitude for all of our families who entrust the care of their children to us.

With Much Appreciation,

Marjorie B. McKnight, M. D.

Welcome Elizabeth Dolan

Year in Review

2019 was an awesome year at McKnight Pediatrics. We experienced wonderful growth and with growth comes change. Though change can be difficulty we are grateful to our staff and families for their tremendous flexibility and abilities to adjust.
We look forward to continued growth and change in 2020. For one thing, Dr. Cohen has decided to move her career in a different direction.
This year her family grew with the addition of a third son. We understand her decision, as the demands of traditional pediatric practice can be overwhelming. We wish her much success in her endeavor, leaving to be an integrative medicine practitioner. It goes without saying that the patients and families who Dr. Cohen provided care for during her time at McKnight Pediatrics will continue to receive excellent care by their new provider.
