Dr. Werner graduated from Tufts University, received her medical degree from Columbia University College of Physicians and Surgeons in New York City and completed her residency at NYU Medical Center. In New York, she learned to treat the whole patient from an internal medicine perspective. Her residency was followed by a medical oncology and hematology fellowship at Memorial Sloan-Kettering Cancer Center. Dr. Werner’s focus was on breast and GI cancers, participating in multiple clinical trials that translated into advanced cancer treatments. Returning to Maryland in 1998, she has practiced medical oncology and hematology continuously since then in Annapolis. Dr. Werner is the recipient of the American Society of Clinical Oncology (ASCO) Merit Award and won the peer-appointed What’s Up Magazine’s Annapolis Top Doc award.

“It is a privilege to be able to be entrusted by people when facing the scariest thing they have ever faced. I take an evidence-based and guideline-based approach and try to tailor a plan that takes both objective data and subjective needs into account. I am direct, honest, and kind…reassuring by helping the patient to understand what our goals and limitations are, so they feel empowered to make decisions based on that information.”

Dr. Werner was born in New York City and grew up in Silver Spring, Maryland. She lives in Davidsonville with her husband, Tom Hattar, M.D. an internal medicine specialist in Annapolis. She has two children; her daughter works on Capitol Hill with an interest in energy policy, and her son is a recent college graduate. Dr. Werner enjoys reading novels, loves traveling and exploring new places on foot.
