About me
Welcome! I’m Dr. Rebecca Aaronson, and I’m so happy to be part of your child’s healthcare team. I believe in creating a warm, respectful partnership with families to help every child thrive.
Biography
Caring for others has always been my passion, and pediatrics truly felt like a calling from the start. I love that this specialty emphasizes education and prevention — empowering families to make healthy choices that support their child’s growth and well-being. Taking care of kids is really fun. I get to laugh every day, and I’m so grateful to do work that continues to bring me joy. In addition to my clinical practice, I’m a proud preceptor for the Kaiser Permanente School of Medicine and enjoy helping to shape the next generation of compassionate, skilled physicians.
About my practice
I value the relationships I build with my patients and their families and aim to make the most of every visit. Time is precious, so I focus on getting to know each child as an individual — who they are beyond just the medical chart. Trust and mutual respect are essential for high-quality care, and I strive to create a safe, open space where families feel heard and supported. It’s through those meaningful connections that I’m best able to provide thoughtful, individualized care.
How I thrive
I find balance and energy through movement, nature, and quality time with the people I love. I’m an avid runner and have completed my first 50k trail race. I also enjoy playing tennis and have been exploring pickleball. At home, I spend time with my 2 daughters and our 2 dogs. I’ve had a plant-based diet for over a decade and enjoy discovering and sharing new recipes that support a healthy lifestyle.
