Our Clinic

The eXtraordinarY Kids Clinic launched in 2007 by Founder and Director, Nicole Tartaglia, MD.

We see children and adolescents with X&Y chromosome variations from within and outside of Colorado. Each patient is unique in terms of their needs and the family’s concerns. Therefore, appointments are tailored to meet the needs of the patient and family. By identifying which providers on our team are most appropriate for the child based on the parental concerns, the child’s age, previous evaluations and current interventions.

The more information provided to our team ahead of time, the better we are in making this determination. Once a child is seen in our clinic, we can determine together whether or not follow-up care is recommended for your child. During each clinic week, our team meets to discuss the results for each patient and to provide comprehensive and coordinated recommendations, considering each individual child and their specific needs.

Feedback sessions are provided within the patient’s schedule in order to meet with the family to discuss these results and recommendations. 

After the clinic evaluation has been completed, each family will receive a comprehensive report with the results from each clinic team member including: a summary of diagnoses, impressions, and recommendations for the parents, medical providers, therapists and educators.

We run clinic two weeks per month, and unfortunately there is typically a waiting list for the clinic. Each clinic has a limited number of appointments with each of our providers, so who your child is going to see can impact how long the waitlist is to be seen. Seeing the entire team often results in the longest wait. Children under the age of 5 may have a shorter wait.
