About Me

I am an adult endocrinologist with the St. Luke’s Center for Diabetes and Endocrinology.  I received my medical degree from the Lake Erie College of Osteopathic Medicine in Erie, PA.  I completed my residency in internal medicine at St. Luke’s University Hospital in Bethlehem, followed by a fellowship in endocrinology, diabetes, and metabolism at Penn State Hershey Medical Center. I enjoy caring for patients with a wide variety of endocrine disorders and diabetes. Helping my patients to understand and feel comfortable with their conditions, results, and treatments is the most rewarding part of my job.

I am board certified in internal medicine and endocrinology, diabetes, and metabolism.  I am a member of the Endocrine Society and American Association of Clinical Endocrinologists.  Additionally, I have published scholarly articles on barriers to genetic counseling and testing in patients with hereditary endocrinopathies as well as primary thyroid lymphoma. I have also presented posters on non-islet cell tumor hypoglycemia and Kennedy’s Disease and its associated endocrine abnormalities.

I joined the St. Luke’s Center for Diabetes and Endocrinology in 2017 where I enjoy treating patients with diabetes as well as a wide range of endocrine diseases.

Dr. Gallagher is top level. My husband's dementia means that I am the at home caregiver and responsible for him. I have had numerous questions over the past 3 months about my husbands diabetes meds and I have communicated via the portal. Dr. G has been fantastic. He gets back to me right away and helps me with my questions and gives me the help I need. He will even call a pharmacy for me if I think I need it. I don't know what I would do without his help and expertise. He is a wonderful healthcare provider who truly cares about his patients(Name)

Dr. Gallagher and his staff scheduled me as the first patient of the day due to my work schedule. Everyone was kind and polite and punctual.
