+ Q: What is a Pediatrician?

A pediatrician is a medical doctor who specializes in the care of children. Pediatricians have undergone special training in the health and illnesses of infants, teens and young adults, and the majority of pediatricians are certified by the American Board of Pediatrics after passing a comprehensive exam.

Pediatricians provide preventive health care for children in good health and medical care for children who are acutely or chronically ill. They also provide parents with support and advice with issues such as growth and development, safety and prevention, nutrition, and emotional wellness to foster a lifetime of good health.

- Q: How often should my child see the pediatrician?

Your child should not only see the pediatrician for an illness. It is also important to schedule well-child-care exams regularly, beginning in infancy. Also called well-care visits or checkups, these routine examinations provide the best opportunity for the doctor to observe the progress of your child's physical and mental growth and development; to counsel and teach parents; to detect problems through screening tests; to provide immunizations, and to get to know one another. Well-care visits are strongly recommended as part of preventive pediatric care.

Well-child visits are also a good time for parents to raise questions and concerns about a child's development, behavior, nutrition, safety and overall well-being.

The American Academy of Pediatrics recommends this schedule for routine well-care visits:

  • 3 to 5 days
  • 1 month
  • 2 months
  • 4 months
  • 6 months
  • 9 months
  • 12 months
  • 15 months
  • 18 months
  • 24 months
  • 30 months
  • 3 years
  • 4 years
  • And once every year thereafter for an annual health supervision visit that includes a physical exam as well as a developmental, behavioral, and learning assessment.
- Q: Why does my child need to receive vaccinations?

Immunizations are a series of shots given to children at different ages to help ward off serious, and potentially fatal, childhood diseases. Making sure your child receives immunizations when scheduled is the best way to help protect your child from potentially fatal diseases. According to the American Academy of Pediatrics, vaccinations have reduced the number of infections from vaccine-preventable diseases by more than 90%. If you're apprehensive about vaccinations, please do not hesitate to contact our office.

+ Q: How do I know if my child’s immunizations are up to date?

Vaccine records/ schedules are reviewed during yearly physical appointments. Dr. Han personally reviews your child's immunization record during the well visits to make sure your child is up to date with their immunizations. Any further questions about your child’s immunization status can be answered during the yearly physical.

Because not all staff are medical trained to determine your child's immunization status, it is difficult to review all your child's immunization records over the phone.

Yes. We have prenatal visits available via telehealth appointments. Most appointments are available during weekdays at 6pm. Please call our office for more information.

- Q: How are you providing a safe environment for your staff and patients from infectious disease?

We do not accept walk-in appointments, however; we have same-day sick appointments available at a first “call” first serve basis.

Yearly physical appointments will not be scheduled on the same day and must be scheduled in advance.

We have same day appointments available each morning. Please call our office at 9am for same day appointment availability.

+ Q: Can I schedule an appointment just to get shots?

If your child's annual check up is up to date (has had a check up within a year), then we allow shot-only visits. There may be a copay charge outside of the annual physical.

We do not offer/ carry any special traveling related vaccines outside of routine vaccinations (i.e. yellow fever, typhoid etc.)


- Q: What do I need to bring to my child's appointment?

Yearly Check ups/ New Appointments

  • Parent ID
  • Insurance card
  • Child’s Immunization Record

Sick appointments

  • Urgent care report/ pertinent information
  • Medication in regards to child’s symptom/ visit
- Q: My child has other concerns I want to address during the yearly physical. Can we do both the check up and sick visits together?

Unfortunately, many insurance carriers do not cover check up and sick appointments (to address other physical and mental health concerns) at the same time. If you have any separate questions or concerns, please schedule a separate appointment. This ensures that an ample amount of time is given to each concern.

- Q: Can you write a referral for my child?

Before writing a referral, we will need to first schedule an appointment to discuss your main concerns to proceed with the appropriate referral process.

+ Q: I cannot attend the appointment with my child. Can my child go to their appointment with a relative or family friends?
  • Because patients under the age of 18 are minors, it is required to have a legal guardian present with the patient during the visit. If you would like for a family member, or family friend to accompany your child to the appointment, we must get a minor consent form signed by the legal guardian. The relative/ family friend MUST BE at least 21 years of age. To complete this form, please contact our office.
  • We CANNOT see minors without the minor consent form.
  • Patients 18 years and older can attend their appointment unaccompanied.

We accept most PPO insurances.

  • Anthem Blue Cross/ Blue Shield
