To All of our Families;
Saturday February 13th, 2020 will be our last Saturday open until further notice.
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 January 1st, 2021.
As we are navigating through COVID and adhering to the constant changes and requirements of social distancing we are requesting that when you arrive to the garage we are asking that you complete the contactless check-in thru the Healow app to let us know you have arrived. Once you have completed the check in please call the office for instructions on entering the office for your appointment.
Please be aware that we do not have a grace period and if you arrive late for your appointment you will have your appointment rescheduled and there is a $25 "missed appointment fee" that will need to be paid before the next appointment can be made.
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.
Thank you for choosing McKnight Pediatrics! Here you can learn a little about us, how to reach the office and what services we offer.
Welcome to our website! First, we'd like to thank you for your interest in us and for taking the time to search for us. We hope you will like what you find and we invite you to return frequently. Next, we'd like to extend our gratitude for the many families who continue to entrust us with the care of their children. Without you we could not exist. We thank you for choosing us, trusting in us, and allowing us to be a part of your village.
We hope that you find our website helpful, informational, and easy to navigate. We welcome any and all comments. Click on the 'Contact Us' tab to learn how to send comments.
