Frequently Asked Questions

When is your office open?

Our office is open Monday – Friday from 8am to 5pm. We close for lunch from 12-1:00pm. We are open for urgent visits on weekends and holidays by appointment only.  Phone lines open on weekends and holidays at 8:30am. On Christmas Day the doctor on call will see patients as necessary.

What do I do when the office is closed?

During regular office hours, you can call our office and our experienced staff will be happy to help you. If your child has an emergency after hours, please call our office phone number. Our answering service will then connect you either to our on-call doctor or our pediatric advice nurse team. For urgent or emergent issues, you can always speak to the doctor on call 24 hours a day, 7 days a week, 365 days a year.

Will I always see my own doctor?

You will choose one doctor as your primary care provider (PCP) at Lexington Pediatrics. This doctor is part of a team comprised of 1-2 other doctors and 2 nurse practitioners. For well visit appointments, we typically alternate visits between your PCP and one of the team nurse practitioners. Sick visits are typically scheduled with your primary doctor or other members of your team, but at times it may be necessary to see one of the other doctors or nurse practitioners in the practice based on available appointments. After-hours calls are shared by all the pediatricians in the practice.

What are the teams of providers?

There are three provider teams at Lexington Pediatrics. Each team is comprised of 2-3 doctors and 2 nurse practitioners.

Dr. Wendy Wornham, Dr. Katharine Garnett, Dr. Johanna Mailloux, Dr. Molly Lederman and Nurse Practitioner Jane Berman comprise the Green Team.

Dr. Victoria Arthur, Dr. Justin Sweder, and Nurse Practitioners Susanne Maher and Rebecca Blair comprise the Blue Team.

Dr. Nuria Gine-Nokes, Dr. Jesse Lock, and Nurse Practitioners Sarah Robbins and Amy Lazaro comprise the Red Team.

What is a nurse practitioner?

Our pediatric nurse practitioners (PNPs) have a master’s degree in nursing (MS or MSN) and have received advanced education, skills, and training in caring for infants, children, and adolescents. All of our PNPs are board certified in pediatrics. PNPs can take medical histories, perform physical exams,

evaluate sick visits, make diagnoses, write prescriptions and provide counseling. Our PNPs work closely with our doctors to deliver comprehensive care to our patients.


What hospitals and specialists do you use?

Before our patients visit a local emergency room, we appreciate a call to our office as we will often be able to see your child promptly and at a lower cost. When our patients do need emergency services, we recommend the Emergency Department at Boston Children's Hospital (BCH) or Winchester Hospital. Winchester Hospital is staffed by BCH pediatric emergency providers. Lexington Pediatrics is a Boston Children's Hospital Community of Care Preferred Practice. This means we can access your child’s BCH medical records quickly and efficiently, and communicate with your child’s specialist of hospital team at BCH directly to make sure we are working as a team. We work closely other hospitals as well, for example, if your child requires care from a specialist, we will refer your family to the provider you or your insurance company prefer. When our patients are hospitalized, we communicate frequently with the pediatric hospitalist staff caring for them, wherever that hospital may be.


Will you see my baby in the hospital?

While at the hospital your baby will be seen daily and cared for by the pediatric hospitalists. When you are admitted for the delivery of your baby, you will be asked who your pediatrician will be. Let them know that you have chosen Lexington Pediatrics, and they will contact us about your baby’s birth.

What insurances do you accept?

We accept most insurance plans. Because your exact insurance coverage varies by plan and your specific policy, we recommend that you call your insurance company to confirm your coverage, PCP, and any out-of-pocket costs. Please bring your child’s insurance card to every visit.


Will I have a copay for my visit?

The healthcare law states that patients will no longer have to pay co-pays for routine pediatric check-ups. Some insurance plans are “grandfathered in”, which means a co-pay is still required for routine pediatric check-up visits. If your insurance plan requires you to pay a co-insurance or deductible, you may be billed for this balance. However, copayments and deductibles are still required for other services. If your provider addresses a specific health issue beyond the routine check-up exam, there will be an additional charge added to the check-up visit charge for the treatment of the illness, and you will be responsible for the co-pay portion of that visit. A routine checkup exam does not include a medical problem that is happening right now.


How often does my child need to be seen?

At Lexington Pediatrics we follow the standard well visit schedule recommended by the American Academy of Pediatrics. We see children at 2-5 days, 2 weeks, 1 month, 2 months, 4 months, 6 months, 9 months, 12 months, 15 months, 18 months, 2 years, and then annually from age 3 to 22. We also recommend a 2.5 year visit, please check with your insurance to determine coverage. 


Well visits are preventative care visits and include services such as history, physical exam, screening tests and immunizations. These visits are also a time for you to ask any questions you have about your child’s growth and development, behavior, and any other questions you may have.

What is your vaccine policy?

Lexington Pediatrics believes that the cornerstone of primary care is prevention. To this end, we expect that all patients in our practice will follow the immunization schedule recommended by the American Academy of Pediatrics and the Centers for Disease Control and Prevention, and will receive all required vaccinations at the recommended ages. 

Can I walk in for an appointment?

We do not offer walk-in appointments. Please call our office to schedule an appointment if your child needs to be seen. If you would like a sibling to be seen, please call us so that we can be prepared for the visit.

What happens if we are late for our appointment?

We understand that it can be hard to get out the door with young children and that there are sometimes unavoidable traffic or parking issues! When planning a visit to our office, please try to arrive 10 to 15 minutes before your appointment to accommodate for this. If you arrive more than 15 minutes late for your appointment, we will try our best to still see your child, however in some circumstances you may be asked to reschedule. If you are going to be late, we appreciate your call to let us know, but you may still be asked to reschedule your appointment depending on when you arrive.

What if the doctor or nurse practitioner is running late?

We make every effort to stay on schedule and we respect that your time is valuable. Sometimes, our patients arrive very ill or with unexpected concerns that require more time. We ask for your understanding and patience if this occurs as we will always give each patient the time and attention they deserve. We will do our best to keep you informed while you are waiting, and offer you the chance to reschedule your appointment or see another available provider if you prefer.

Do I have to accompany my child for his or her appointment?

If a parent or guardian is not able to accompany the patient to their visit, please send a reliable caretaker/historian in their place with a note giving us permission to speak with them (unless you have documentation on file). Please also be available by phone to consent to any necessary treatments or immunizations or to discuss follow-up care.
