Our Practice

Our Team

We are a group of board-certified pediatricians dedicated to providing the best of care for children ages birth through 21.  We welcome and treasure families from our richly diverse Washington suburbs.


Our office offers well child care, immunizations, and the latest in treatment and advice for childhood and adolescent illnesses.  We take a special interest in care of the newborn, breastfeeding, child development and behavior.  Asthma, allergies, common infections, obesity and ADHD and other learning challenges are some of our areas of interest.

Our Practice - Are we a good fit?


Our office should be your first contact when your child is sick. Please call our office before visiting an urgent care center or seeing a specialist.  We can guide you to those specialists we feel provide the best care to children. Please ask that any specialist you see sends a report directly to our office.  Your child’s health is optimized and consistent with care coordinated by your child’s pediatrician.


Our office follows the schedule set by the American Academy of Pediatrics and the Centers for Disease Control (CDC). We feel most strongly that vaccines continue to be a primary part of our mission in ensuring the health of children. We discourage any deferral of vaccines for patients in our practice.


Our office is committed to the judicious use of antibiotics. We follow evidence-based guidelines that provide appropriate treatment and avoid unnecessary treatment.  This decreases many risks, including risks of resistance and side effects.



We attempt to allocate adequate time for every appointment we schedule. Please inform us of all of your concerns when scheduling an appointment so that we can allot the right amount of time to thoroughly address each issue. We hold open same-day time slots for sick visits. We request that you call as soon as possible if you cannot keep an appointment so that time may be made available to other children in need. Well visits can be scheduled up to 6 months in advance.



Please remember that preventive care is a vital part of child health. We approach well visits with a list of topics to address. If you anticipate discussing other, ongoing health issues at a well visit check-up, one of two things will occur: 

(1) if time does not permit, you will be asked to schedule a follow-up visit to address that issue

(2) if time permits, we will address, manage, and document the concern(s).  Your insurance company will assess a co-pay for the concerns that are outside the scope of well care.



We make every attempt to keep to our schedule as we know that your time is valuable. Please call our office if you are running late. If you have missed your appointment time, we may have to reschedule your child.
