Your Pediatric Practice in Frankfurt/Main
Sarah Rugilo & Dr. Christina Semmler
Dear children, dear parents,
as of July 1, 2026, we will be taking over the practice of our esteemed colleague Ursula Mertes, and we are delighted to welcome you in familiar surroundings.
We care for children from their very first day of life through young adulthood with medical expertise, empathy, and experience. Whether it is a preventive check-up, an acute illness, or the small and big concerns that come with everyday family life, supporting the whole family in a trusting and reliable way is very close to our hearts.
From our own experience, we know that life with children is wonderful, but it also brings many worries and questions. That is why, for us, not only medical guidelines matter, but above all your child’s well-being and a trusting partnership with you on equal footing.
We are very much looking forward to getting to know you and to accompanying your family along part of its journey.

Appointment booking: Please book all appointments online only via the arzt-direkt app. You can download the app hereand link it to your child’s medical record. This link must be activated in person at the practice, and our team will be happy to help you.
Communication with the practice: If you would like to contact us personally, or if you have questions regarding appointments or requests for forms (follow-up referrals, repeat prescriptions, or an extension of a child sickness certificate), please use only the messenger service in the arzt-direkt app. This service is secure and reliable. Emails cannot be processed on a same-day basis.Digital waiting room: When attending your appointment, please use the express self-check-in so that you can be admitted to our digital waiting room immediately. Instructions are available directly at the reception desk.
Data protection consent form: Please bring the signed consent form for patient data in case of practice takeover and the consent form for data processing with you to your first visit. Due to the practice takeover, we also ask existing patients to submit the forms with their signature as a one-time requirement.
Hygiene: For hygiene reasons, we separate our well-child check-up and vaccination clinic for healthy children and adolescents from our acute care clinic for sick children. We therefore ask you to always book an appointment and, in cases of acute illness, to come with only one accompanying person. Please also book appointments for acute illnesses online at all times.
Cancellation: If you are unable to attend your appointment, we kindly ask you to cancel as early as possible. Via the arzt-direkt app, acute appointments can be canceled up to 6 hours in advance, and all other appointments up to 24 hours in advance. This allows unused appointments to be made available to other patients. If well-child check-up or consultation appointments are not canceled in time, we will unfortunately have to charge for the missed appointment.
Team
Sarah Rugilo
Since I was young, I have had only one career aspiration: to become a pediatrician. And every day, I discover anew how much joy my work brings me.
I first studied Human Medicine at the University of Greifswald (2001–2004) and later at RWTH Aachen (2004–2007). From 2008 to 2014, I worked at Hanau Children's Hospital, initially as a resident physician and, after being certified as a specialist, as a staff physician in the pediatric department.
For the past 10 years, I have been working as a employed pediatrician at a children's clinic in Frankfurt. I am a mother of two daughters.

Since high school, I was already certain that I wanted to become a pediatrician. As a native of Frankfurt, I gained early insights into pediatric medicine through internships at Clementine Children's Hospital and at Frankfurt University Hospital – experiences that continue to shape me today.
From 2006 to 2013, I studied Human Medicine at Johann Wolfgang Goethe University Frankfurt am Main, followed by my doctoral research at the Department of Child and Adolescent Psychiatry at Frankfurt University Hospital. My thesis focused on "Neuromotorics and Imitation Ability in Autism Spectrum Disorders and Schizophrenia."
I completed my specialist training in Pediatrics and Adolescent Medicine from 2014 to 2022 at Gelnhausen Children's Hospital – accompanied by the births of my two children (2017 and 2020). I am also qualified as a Neurodermitis trainer according to AGNES standards. Most recently, I worked in various pediatric practices in Frankfurt, and since February 2024, I have been practicing as a specialist physician.
