Our Services
Infancy, childhood, adolescence, and young adulthood are delicate periods for a child. Well visits are an essential part to live a healthy life. It is important to keep up-to-date with your child’s visits and immunizations.
Routine Well Visits
Our pediatricians monitor your child’s growth to ensure they meet all milestones and benchmarks. We provide easy-to-follow care schedules for your child based on age, medical history, and other essential factors.
Well visits include:
- General screenings
- Immunizations
- Lab work
- Physicals
Sick Visits
When your child experiences a common illness, our pediatricians are available to treat your sick child as soon as possible in a compassionate, friendly environment. Patients can also access specialty clinicians should an illness require advanced diagnostic attention or care.
Immunizations
Immunizations and vaccinations are important to shield your little one against preventable diseases, such as whooping cough (pertussis) and measles, which can be extremely dangerous to your children. It is important to stay on top of your child’s immunization schedule by attending all your child’s well visits.
Minor Injury Care
Much like sickness, injuries tend to occur suddenly and without warning. If your child suffers a minor injury and requires medical attention, our pediatricians can apply the treatments needed for proper healing.
