Nicole Tartaglia, MD, MS
“Dr. T” is a Developmental Pediatrician and the Founder and Director of the eXtraordinarY Kids Clinic. She has seen more than a thousand patients with all varieties of X&Y chromosome variations during her tenure. She often spends several hours with families, and sometimes over two separate appointments.
 
As a medical doctor, she will review the medical, developmental and behavioral history, address questions and concerns about the child and their diagnoses, and make recommendations for the medical and developmental care of the child being seen. With older children, she will often request to spend time with the child as well as the parents separately. She conducts and oversees developmental testing for infants and toddlers with a prenatal diagnosis to monitor development and determine the initiation of therapies that may be needed.
 
Susan Howell, MS, CGC, MBA
Susan Howell is a board-certified Genetic Counselor and she serves as the eXtraordinarY Kids Clinic, Clinic and Research Coordinator. She provides prenatal genetic counseling and serves as the initial contact for families coming to clinic. She can address general questions and concerns about the conditions, make recommendations for evaluations, and facilitate getting you ready to be seen in our clinic.
 
As a Genetic Counselor, she will gather information about the family history and interpret any implications, explain the genetics of your child’s condition and any implications, and counsel families and children about what X&Y chromosome variations are, what it means to you, how to talk about the condition, and concerns you may have about the diagnosis. In addition, should you choose to participate in our research, she will direct you into the appropriate study and facilitate any referrals necessary.

Dr. Janusz’s research interests include examining the impact of neurocognitive deficits on a child’s social, adaptive, and behavioral functioning. A neuropsychological evaluation with Dr. Janusz includes a thorough assessment of a child’s cognitive strengths and weaknesses, academic achievement profile, as well as other domains such as attention, memory, executive functions, and visual-spatial abilities. Results of these assessments are used to establish diagnoses, and provide recommendations for interventions and strategies to be used at home and in the school setting. 
 
Richard Boada, PhD., ABPP-CN
Dr. Boada is a board certified clinical neuropsychologist with expertise in the neuropsychological features of genetic disorders including X&Y variations, Down syndrome, and other neurodevelopmental learning disabilities. He also works with children who have other neurologic conditions, such as epilepsy and stroke. Dr. Boada’s research interests include language-based learning disabilities (e.g., dyslexia), executive function deficits, and ADHD.  
 
A neuropsychological evaluation with Dr. Boada includes a thorough assessment of a child’s cognitive strengths and weaknesses, academic achievement profile, as well as other domains such as attention, memory, executive functions, and visual-spatial abilities.
