At Eden Park Pediatric Associates family service navigation is about creating a seamless experience for the patient and their family while receiving pediatric services in their medical home.  Ashley Zepp, our Family Services Navigator, who works out of our main office on Oregon Pike in Lancaster, provides guidance and support to patients and their families in their Eden Park medical home practice. The role of the Family Services Navigator is to eliminate perceived barriers to scheduling appointments with their primary care clinician and act as a support hub for all aspects of the patient's care provided by our office staff, pediatricians, Nurse Practitioner, Lactation Consultant RNs, Pediatric RNs and clinical staff.

Eden Park’s Family Services Navigator, Ashley Zepp, FSN, focuses on collaboration between the entire healthcare team, which includes your child and your family. Our Family Services Navigator (FSN) has years of experience working with children and their families at Eden Park Pediatrics.  Ashley welcomes new patients to the practice’s medical home pediatric services, schedules and personalized patient web portal on our website,, shares information about Eden Park’s healthcare team; and introduces the team’s commitment to responding to the child and their families needs. The FSN encourages the child and/or their family to be involved in their care by documenting emerging questions for their provider either through their patient web portal in a message to their primary care provider OR for children with  complicated needs, through their assigned CDM Pediatric RN. Another goal of this service is to ensure our children and families feel supported at all times. That is why the FSN provides her contact information so the patient can call upon Ashley as a resource for general information or questions and concerns.

Our FSN has a wealth of knowledge of resources and services throughout the practice and the community. She even helps to bridge the gap from the hospital to the care of your primary care pediatrician or pediatric nurse practitioner at Eden Park to the next level of care by sharing community resources and completing post-discharge phone calls to make sure your child and family has what they need.
