Medical genetic evaluations and personalized genetic testing are powerful tools as gene discovery and medical technologies continue to advance at an rapid pace. My goal is to offer my patients the best care, help families and physicians access the most state of the art testing, as well as provide guidance for treatment and preventative health using a multidisciplinary approach. Our geneticists and counselors provide expertise and support for individuals concerned about genetic screening/testing, prenatal counseling, or risk assessments due to family history or ethnic ancestry.
I have the privilege to provide comprehensive clinical genetic evaluations and lifelong care for children and adults at risk for genetic disorders. With my pediatrics background, I help families and referring physicians assess if differences that are noted prenatally, at birth, or during childhood may affect growth and development, as well as identify the causes which could lead to later problems with health, learning, and/or social interaction. All too often, patients are treated by multiple specialists without a clear explanation about the cause of their issues. As a parent, I want to help find answers for those undergoing a stressful diagnostic odyssey and obtain coordinated quality care to meet your child or family's unique needs.
