Welcome to Step By Step Pediatrics

We are committed to providing you and your children with top quality pediatric care. We believe that the care of your child is a partnership built upon our knowledge of pediatrics and your commitment to your child's well-being. We strive to remain current with advances in pediatric medicine and consider educating our families a top priority. We look forward to the opportunity to develop long lasting relationships with our patients and their families.

Practice Overview

Appointments & Scheduling

Patients are scheduled by appointment only. Appointments can be made by calling during our office hours. It is helpful to schedule check-up appointments 2-3 months in advance. We will make every effort to arrange appointment times that are convenient for your busy schedule.

If your child is ill and you wish to have him/her seen that day, it is best to call early in the morning so that we may accommodate your scheduling needs.

Your appointment is reserved exclusively for you. We ask that you arrive for your appointment 10-15 minutes early so there is time to park and check-in with our receptionist. Patients arriving late for appointments may be asked to reschedule so that the remainder of the day’s patients can be seen on time. If you are unable to keep your appointment, please give at least 24 hours notice so that another patient may be given that appointment time. You may be billed a “no show” fee for appointments that are not cancelled in a timely manner.

Please call between 8:00 a.m. and 5:00 p.m. Monday through Friday to schedule appointments, to request prescription refills, or to ask brief medical questions. The phones tend to be busiest in the early morning, especially on Mondays and Fridays. For your convenience, you may wish to wait until the afternoon for issues that do not require immediate attention.

We have nurses available by telephone to answer many of your questions. They are specifically trained to counsel you, following guidelines set by our physicians. They can help you with questions regarding well baby and child care. They can also advise you on the care of an ill child and help determine if your child needs to be seen by a physician.

Step By Step Wellness

We promote optimal growth and development with healthy lifestyle practices for children and families. We offer yoga classes, individual and group fitness training, and healthy cooking courses that you and your whole family will enjoy.

Pediatric Nutrition Classes

Is your child a COPC pediatric patient? If so, our free classes can help you learn practical tips to improve your family's nutrition! Our Registered Dietitian Nutritionist facilitates each class and will give you the most up-to-date recommendations for your growing child. Children who attend will be engaged with activities and food samples to help expand their knowledge as well as their palate. Check out our pediatric nutrition page to see how you can get started!

Pediatric Support Centers

Our Support Center provides care to COPC families that’s exceptionally better than the traditional Emergency Room and Urgent Care experience, at a significantly lower cost. Scheduling an appointment (through your child’s COPC pediatrician) with our Pediatric Support Center allows your child to be seen by one of our outstanding pediatricians after typical office hours and on weekends.
