Hawaii Community Genetics (HCG) was created as a collaborative effort of the Department of Health (DOH), Hawaii Medical Service Association (HMSA), Kapiolani Medical Center for Women and Children, Queen’s Medical Center, and the University of Hawaii John A. Burns School of Medicine. In the future, more local partners will join the collaborative group. Dr. Robert Wallerstein is the medical director and one of the clinical geneticists at HCG.

Dr. Robert Wallerstein comes to our state from California where he worked as a clinical geneticist and Director of the Silicon Valley Genetics Center at Santa Clara Valley Medical Center. He is board certified by the American Board of Pediatrics and American Board of Medical Genetics. Dr. Wallerstein has extensive experience working with pediatric, prenatal, and adult patients.

Clinical support services at HCG are provided by Sansan Lee and Lianne Hasegawa-Evans (Kapiolani Medical Center); and Gwen Palmer, Michelle Maeda, Jennifer Boomsma, Lila Aiyar and Michelle Takemoto (DOH).  HCG continues to contract with the Stanford University School of Medicine Genetics Program to provide periodic support for clinical pediatric and adult genetic services and genetics education.
