The mission of Bay West Endocrinology Associates is to provide comprehensive state of the art endocrine services in a caring, professional and supportive manner.


As our health care system evolves, Bay West Endocrinology Associates is committed to keeping up with these rapid changes. We will remain dedicated to offering the highest quality care for our patients, utilizing evidence based practices, in a cost effective manner. Our valued board qualified physicians will work as a team to coordinate care with primary care physicians and specialists, hospital and health care organizations, and public and private insurers.

Our Core Values

Quality: We offer the most advanced medical care available to the patients we serve. We promote prevention before treatment.
Respect: We respect diversity and individuality and hold each patient’s unique circumstances at the forefront of clinical care decisions.
Integrity: We commit to regular self-evaluation of our practice and continuous quality improvement to assure patient safety, the best possible clinical outcomes and the optimal use of medical resources.
Education: We are committed to providing outstanding education and training for current and future generations of health care 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 health care 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. Ths 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. In addition to performing these services for our patients, we are actively involved in clinical research of endocrine diseases in conjunction with MODEL Clinical Research, LLC.

MODEL Clinical Research works extensively with many pharmaceutical companies to conduct clinical trials in type 1 and type 2 diabetes, hypertension, osteoporosis, lipids, cardiovascular diseases, neurology, renal diseases, and obesity. We have several clinical research coordinators and an on-site lab for blood drawing and processing.

Our office is located at Greater Baltimore Medical Center, in Towson, Maryland. Office hours, address, and phones 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.
