Our Core Values

Education: We are committed to providing outstanding education and training for current and future generations of healthcare professionals.
Partnership: We pursue our clinical mission in close partnership with two major hospitals, our health system, and with key community physicians.
Professionalism: We believe our doctors and staff are our greatest asset and recognize and value the contributions of each member of our healthcare team.

Bay West Endocrinology Associates (formally James H. Mersey, M.D., P.A.) is one of the largest groups of endocrinologists in private practice in the Mid-Atlantic region. We have been in practice since 1981, and have been growing steadily since that time. The reasons for that growth relate to how we practice Endocrinology.

Our physicians are all University trained and are very experienced in treating endocrine diseases. We deliver our knowledge with the maximum concern for our patients and their families. It is our level of communication with our patients along with our knowledge that equals happy patients and improved care.

We have a sophisticated computerized medical record system. This enables us to better deliver consult notes to physicians, portal messages, telephone and lab communications to patients, and inter office communications to secretaries and lab technicians to maximize efficiency in ordering tests.

We have expertise in Bone Density, Ultrasound, and laboratory testing that relate to endocrine diseases. All of this testing can be done in our offices, often at the time of the visit.

Our office is located at Greater Baltimore Medical Center, in Towson, Maryland. Office hours, addresses, and phone numbers are listed below. Please read the brief biographies of our physicians so you may get to know us better. These can be found under Meet the Team.
