WELCOME ADVOCARE ARDMORE CHESTNUT PEDIATRICS AND ADOLESCENT MEDICINE PATIENTS!

Welcome to Advocare Fairmount Pediatrics!

We are a community-based Pediatric and Adolescent Medicine practice established in Philadelphia in 2009 and in Montgomery County in 2023. Our goal is to provide excellent, accessible, comprehensive medical care to infants, children and teens in our community, from all types of families. We care for young people from birth through their 21st year.  


Our philosophy is threefold: 

  1. Excellent medical care is our top priority. We maintain thorough and up-to-date standards of care in all that we do. 
  2. Communication is paramount. We strive to keep open, clear lines of communication with parents and with children in our practice. 
  3. Parents matter. In all that we do, we seek to support our patients’ parents, providing you with the services you need to care for your child. 

Our pediatricians offer same day sick visits, an open access schedule so that you can always get an appointment within 2 weeks for a well visit, telehealth appointments for behavior discussions, and on-site physical therapy, speech therapy and behavior therapy. Vaccinations are encouraged and parent's choice is respected.


The program at Fairmount Pediatrics and Fairmount Pediatrics Montgomery County includes a unique offering: the Affiliate Program, in which a variety of providers care for patients on-site, within each office. These providers include a physical therapist, a speech therapist, a behavioral therapist, a psychologist, a lactation counselor, and a nutritionist. These offerings do not replace high quality pediatric care, but rather add to it, offering a truly holistic approach to health.

Karen S. Wosiski, CRNP

Hello, my name is Karen Wosiski. I am a pediatric nurse practitioner, or CRNP. I first became a registered nurse after graduating from Abington Hospital School of Nursing. I worked for 12 years as a staff nurse and then went on to earn my BSN from Jefferson University College of Allied Health Sciences. I made the decision to specialize in pediatrics and received my MSN in the Nursing of children from The University of Pennsylvania. Since then, I have taught nursing and served as Renal transplant coordinator for St. Christopher's Hospital for children. I went back to The University of Pennsylvania for my Nurse Practitioners license and then spent 3 years in a post-master's program at The Family Institute of Philadelphia, earning a certificate as a family therapist. During my time as a transplant coordinator, I became aware of the need for psychological support for families dealing with childhood illness. I also discovered my love for working with families over time, developing trusting relationships, and watching children grow. Pediatric primary care has been a perfect fit for me. I have been fortunate enough, in my work as a pediatric nurse practitioner, to get to know families from the birth of their infant to their child graduating from College. It has been an honor to help them remain healthy, assist in health crises, and help manage ongoing chronic illnesses. In my last position, I worked in primary care at Laurel Pediatrics for 17 years. Because of my mental health skill set, I was able to do behavioral evaluations, manage ADHD, depression, and anxiety, in addition to the daily sick and well children that I met and cared for each day. I am excited to be part of Advocare Fairmount Pediatrics. It is a dynamic team with three locations. Their impressive facilities include a lab, lactation consultant, psychologist, and nutritionist, as well as experienced and caring providers and accessible staff. I love going to work each day, meeting new children, managing their care, teaching where necessary, and forming bonds with families. It's a joy to be a trusted part of the team that cares for your children. I look forward to meeting you soon.
