Caring for Children, Our Most Important Asset

Advocare Broomall Pediatrics believes that children are our most important asset. Guided by this belief, we strive to provide the highest level of health care for infants, children, adolescents, and young adults. We follow the recommendations of the American Academy of Pediatrics and partner with parents to provide comprehensive health care for children from birth until their 24th birthday.

Our physicians, physician assistant, nurse practitioners, and registered nurses offer a broad range of experience and talent to best meet the diverse needs of our patients. Special areas of interest and expertise include asthma, infectious diseases, ADHD, and new parenting issues. We even have a Certified Lactation Consultant on staff. Additionally, we gladly and confidentially discuss topics such as school, parents, dating, drugs, alcohol, and sexuality with our adolescent and young adult patients. We work to build trusting relationships with patients and their parents.

For your convenience, our offices are open 7 days a week. We also offer evening hours Monday through Thursday to accommodate busy families. Equipped with exam rooms, laboratories, procedure treatment rooms, and separate waiting rooms for well and sick children, both offices are accessible for patients with disabilities. Our goal is to provide the highest standard of care in a warm and friendly environment.

News & Announcements

To my dear families and patients,
It is with very mixed emotions that I announce my retirement from active practice as of July 2, 2020.  I have enjoyed 36 wonderful years at Broomall Pediatrics, beginning in an old white house on West Chester Pike.
I have been fortunate to care for generations of families.  Watching your children grow was incredible, veritable time lapsed photography.  Along the way from diapers to driver’s permits we navigated our visits with puppets, books and songs.
I thank you for your generosity and humor.  I was humbled and inspired by your strength and bravery.  You have been my heroes over the decades.
Our visits and your journeys from infancy to adulthood will be treasured.  I appreciate the loyalty you have shown me throughout the years and the trust you placed in me.
I will leave Advocare Broomall Pediatrics knowing that you will be in the excellent care of our knowledgeable and compassionate team of doctors, nurses and staff.
I wish you continued good health and all the best in the coming years.
Lisa O’Mahony MD
The COVID-19 pandemic has changed every aspect of all our lives for now and in the future. How we work, how we educate our children, as well as how and where we get our healthcare. With social distancing and the need to be safe, a lot of your healthcare is now being done via Telehealth whenever possible and prudent. We are still available to see children who require an in-office visit and we do so carefully, taking precautions for your family and our own staff’s safety.

We know that there are a lot of questions surrounding Coronavirus Disease 2019 (COVID-19). It’s important that you keep your children calm and give them age appropriate information to help them stay healthy. We advise getting plenty of sleep/rest, regular washing of hands and avoiding people who are sick. Hopefully you will gain some insight here on what we feel is important to know and how best to protect you and your family.

We are proud to announce that Halette Anderson, MD, Joseph Becker, DO and Lisa O'Mahony, MD were all selected as one of the 'Top Doctors' in Philadelphia Magazine for 2018 AND 2019! This prestigious honor was bestowed on them by their peers who nominated them as the very best in their field. As physicians with more than 100 years experience between them, we are happy and proud to call them our own. Cheers to another 100 years! 
The best place for children to receive medical care is at a pediatrician's office. But, sometimes kids don't wait for office hours to get sick or injured. So, what should you do for those times when your baby runs a high fever during the night or your young athlete hurts his wrist at a weekend practice? It happens. Click on the title above to read more...

Busy with college, work and just life in general, we found that young adults often fail to get the recommended annual check ups to maintain their good health. For this reason, our physicians have extended the age limit on our patients until their 24th birthday. 
If you are primarily a patient in the Broomall location you can always go to the West Chester location for walk in. No matter where you go, we are your medical home! 
The American Academy of Pediatrics (AAP) recommends that all children ages 6 months and older receive a flu shot this season with the goal to provide the optimal protection against all strains of influenza.
