New Billing Company

Dear Wonder Kids families,

Our pediatric practice has recently switched to a new billing company. This change was needed to help our office keep up with the ever-changing and complex world of medical insurance, and to ensure that our billing processes are as accurate and efficient as possible.

We understand that billing and insurance can be confusing and overwhelming, and we want to help simplify it as much as possible.

Our new billing company is experienced and committed to providing you with clear, concise statements and answering any questions you may have.

We appreciate your patience and understanding during this transition, and we want to assure you that we will do everything in our power to make the process as smooth as possible. If you have any questions or concerns, please don’t hesitate to reach out to us.

Thank you for entrusting us with your child’s healthcare needs. We look forward to continuing to serve you with the same high-quality care that you have come to expect from us.

Sincerely,

Wonder Kids Pediatrics
