✨ Meet Alexia! ✨

Alexia joined our team this month as a Medical Assistant, and we’re so excited to have her!

🎉 She’s a graduate of Rutgers and brings a great energy to our office every day.

When she’s not helping take care of our patients, you can find her baking sourdough bread 🍞, watching movies 🎬, or hitting the gym 💪.

We know you come to see the doctor, but it truly takes a team to give you and your family the best experience possible and Alexia is a big part of that! ❤️

Here she is helping us get stocked up and ready for all of you! 📦.

🌙 Create a dark, quiet, and comfortable sleep space.
🌙 Stay patient while your child works through this phase.

Patient artwork adds a personal touch to our space and reminds us why connection matters in care.

We love receiving drawings from our patients, even a doodle!

A federal judge in Boston has temporarily blocked key parts of HHS’s childhood vaccine policy after ruling in a case brought by the AAP and other medical organizations.

A stay granted by Judge Brian Murphy halts the implementation of HHS’s reduced childhood immunization schedule released earlier this year and halts the 13 recently appointed members of the ACIP vaccine advisory panel from serving ahead of their planned meeting later this week. The court also invalidated prior votes taken by the panel to change vaccine recommendations.

❤️ Strength. Community. Gratitude. 🩸

We’re so proud to see Dr. Doyle and her family featured by the American Red Cross. During her 4-year-old daughter’s leukemia treatment, lifesaving blood transfusions made all the difference.

This story is a powerful reminder that blood donors truly save lives. ❤️

And a big thank you to Dr. Farrington for hosting!

If you’re able, please consider donating.
