Dear Patient Families: 

Thank you for entrusting Pete and myself with your children’s healthcare needs here at Dr. Bill and Dr. Pete for the past 23 years.  It has been more than a pleasure to serve you and certainly a privilege that we do not take lightly.

With that being said, we are sending this letter to inform you that we are making changes to our practice and are joining the Cook Children’s Physician’s Network starting on January 16, 2023.  No, we are not retiring and no we are not changing anything about how we take care of your children.  Pete and I and the staff that you have come to know over the years will still be here every day, just as we are now.  As a matter of fact, the only big change that you might see when pulling into the parking lot will be the new sign above the door that says “Cook Children’s”.

On the inside and behind the scenes is where the changes take place.  We will still give you the great service and care that you are accustomed to.  That will not change.  What will change are things that we know will benefit you.  We will now be a part of a system that has been caring for children for over 100 years and will have access to all their resources and state of the art facilities.  We will have a new computer system that will have an electronic medical record system that will be a little different than the one we currently use.  This system will give you, the families, greater access to your children’s records through a patient portal, as well as the ability to schedule appointments on line. 

So please know that we are excited about our future as a member of the Cook Children’s family.  We look forward to continuing to serve your children and your family for many years to come.  Should you have any questions, please feel free to call and ask, or inquire about things at your next visit!


Thank you!



Dr. Bill  & Dr. Pete
