OB/GYN Department

Print

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. 

Dr. Michael Lantz is a Board-certified Obstetrician-Gynecologist specializing in Maternal-Fetal Medicine, who is heading up our Perinatal Center in our Salisbury location. Dr. Lantz has joined Chesapeake Health Care in our OB/GYN office to provide specialized testing, and ongoing monitoring, and will perform necessary procedures for high-risk pregnancies. High-risk pregnancy factors include diabetes, hypertension, multiple gestations, advanced maternal age, etc. Genetic evaluations are also available.
