Areas of Expertise
An internist is a physician who focuses on the diagnosis and treatment of conditions that affect the adult population—both acute and chronic.
These doctors are often who adults see as their primary physicians because they treat a broad range of illnesses that do not require surgical or specialist interventions. They also work to help a patient maintain optimal health in order to prevent the onset of disease.
In addition to treating the common cold and flu, internists also treat chronic diseases like diabetes and heart disease.
A hematology specialist is an expert in disorders of the blood, the blood forming organs and bone marrow. These doctors diagnose, treat and work to prevent diseases that affect the production of blood and its components, as well as the ability of the blood to perform its many functions, such as coagulation and carrying oxygen to the lungs and tissue.
Hematologists diagnose and treat blood disorders, such as anemia, hemophilia, leukemia, sickle cell anemia, deep vein thrombosis and pulmonary embolism.
Depending on the condition, hematology specialists may treat a patient with a blood transfusion, stem cell transplantation, bone marrow transplant, radiotherapy, anticoagulation therapy or medication.
Jeffrey A. Buckner, MD
Jeffrey A. Buckner, M.D. is board certified in internal medicine and hematology and practices at NYU. He has trained at three major NYC teaching hospitals (Mount Sinai, NYU, and Memorial Sloan Kettering, as well as at the New York Blood Center).
He believes in effective communication and collaboration with his patients and communicates with them readily to discuss their care and to minimize unnecessary office visits. He is convinced there is a direct correlation between the time he spends with patients and their individual health outcomes. Because of this, in early 2019 Dr. Buckner transitioned the general medicine portion of his practice to a concierge model. The concierge model of care is personalized to each patient’s health needs and provides Dr. Buckner with unhurried time during each office visit.
He seeks to determine an approach and treatment plan that are in the patient’s best interest, and with which the patient is in full agreement, often providing the patient with articles from the medical literature or excerpts from medical textbooks, as well as with referrals to relevant specialists for further discussion and treatment if necessary. He has a particular interest in patients whose problems have proved difficult to diagnose or treat in whose service he can involve the wide circle of preferred specialists throughout the city to whom he can refer. He places a high value on avoiding unnecessary tests and procedures and with resolving clinical questions with information (see Atul Gawande, America’s Epidemic of Unnecessary Testing).
He graduated from Columbia College in 1974 and from medical school at the Icahn School of Medicine at Mount Sinai in 1978. He completed his residency in internal medicine at New York University Langone Medical Center in 1981. His fellowship in hematology and oncology was earned in 1986 at Memorial Sloan-Kettering. Dr. Buckner is a member of the American Society of Hematology, and the American College of Physicians. He has been named the Clarence Haskell Scholar by the Leukemia Society of America.
He continues to see hematology patients in a traditional care model. His primary focus in hematology is non-malignant blood disorders, including coagulation problems, and disorders that affect fertility, clotting, and infection.
