Our warmest wishes for a Happy Retirement to Dr Linda Liu from the physicians and staff at Endocrine and Diabetes Associates! We’ve been privileged to work together since 1983, when Drs Liu and Petrick started their fellowships in Endocrinology at NIH, and later joined together to start our group.

We are thankful for Dr Liu’s many years of dedicated service to us and for her expert care of our patients. Dr Liu’s letter to her patients can be viewed in the Our Physicians section. We are pleased to welcome Dr Natasha Kasid who has joined our practice and will provide ongoing care to Dr Liu’s patients. Dr Kasid is a native of Montgomery County. She completed her Endocrine fellowship at Beth Israel Deaconess Medical Center and Joslin Diabetes Center in 2016, and remained at the Centers and at Harvard Medical School as a Staff Physician.
