Our team of Genetics providers includes medical geneticists and genetic counselors who evaluate both pediatric and adult patients with known or suspected genetic conditions. Our physicians perform thorough evaluations in order to diagnose a wide variety of genetic syndromes. In addition, our genetic counselors gather family medical history, facilitate genetic testing, and provide information and support to patients and their families. We see patients both for initial diagnosis and in follow-up as needed.
