Why are you passionate about the Clinic?

What draws me most to the Clinic is its extraordinary mission and the meaningful impact it has on the individuals and families it serves. It is inspiring to see an organization that not only provides world-class care for people with rare genetic conditions but also works to eliminate barriers by ensuring that care remains accessible. The combination of compassionate, patient-centered care, groundbreaking research, and strong partnerships with the Amish and Mennonite communities makes the Clinic truly unique.

Equally impressive is the Clinic’s culture, where every team member is united by a shared commitment to improving the lives of patients and their families. That sense of purpose, collaboration, and dedication to excellence is what makes the Clinic such a special organization, and it is exactly the kind of mission-driven environment I am excited to be a part of.

Why are you passionate about the Clinic?
I am passionate about the clinic because when searching for a job, I came across the Clinic and its mission to serve the Plain Community. I grew up in Lancaster, so I have always been surrounded by the Plain Community. This job stood out to me and drew me in because I knew that my work would be helping the Plain community, and I could directly see the impact it had. When I graduated from college, I was unsure of what I wanted to do specifically with my degree. However, I was sure that I wanted to help individuals as much as I could. After meeting the staff at the Clinic for Special Children, I determined that this would be the perfect fit for me!

She earned her certification as a Primary Care Pediatric Nurse Practitioner from the American Nurses Credentialing Center in 1995.

Why are you passionate about the Clinic?

I’ve always appreciated the personal touch the Clinic has for each patient, where every patient is a child and not a disease to study. Education of the family and patient is a priority so the family can make informed decisions and be active participants in their care. Donna, famous at the Clinic for her cakes, shares that care at the Clinic is tailored to the patient and not a “cookbook” protocol.
