The Chesapeake Health Care Obstetrics/Gynecology department is located in both Princess Anne and Salisbury, and is accredited by the Ultrasound Practice Accreditation Council of the American Institute of Ultrasound in Medicine (AIUM). Chesapeake Health Care earned three accreditations in the areas of first, second, and third trimester obstetric ultrasound. This is the first time that our Perinatal Center has earned this distinction that recognizes the high-quality ultrasound we provide for our patients. Chesapeake Health Care’s Perinatal Center in Salisbury, Maryland is the only practice on the Eastern Shore to be awarded this coveted accreditation.
Our Obstetrics Department provides prenatal care for Moms-to-be. Our Gynecology department provides preventive and acute gynecologic care to all women throughout their lives.
