Announcements-Please Read

Just a little update on our transition to Cook Children's. We know that everyone has been on long hold times, that is due to the fact that we have to register each patient, we have a lot of patients already registered but it seems that not everyone is registered. That process takes time. We also had some issues with the phones transferring due to the lines being moved from Spectrum to AT & T. That was not fun and we had lost time and it caused everyone to be frustrated-not an excuse but that is what happened.
We are working hard to make this transition smooth and we ask for your patience as we know it is frustrating- getting all this new technology is going to make things easier in the long run but we have some growing pains to work through.
Some interesting information:
Our phones are temporary being routed to a phone center at Cooks in Fort Worth, the people who are answering the phones are registering patients and making appointments but there are only a few people who are doing this- we are working on getting our staff up and running so we can take your call personally as we have in the past but it is going to take a bit as we are learning the new system - I do know 2 of my staff members answered calls today- so it is moving in the right direction- again we ask that you understand that we want to answer the calls ourselves as we want to give you the personalized service we have given over the years.
So that everyone knows- you can reach our office with our 2 numbers- 972-370-2425 and 945-204-7920

Thank you

Letter from the Doctors _____________________________________

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.  Ihas 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
