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, hematology and addiction medicine.  He is passionate about the care he provides every patient and is convinced there is a direct correlation between the time he spends with patients and their individual health outcomes.

Because of his passion and conviction, Dr. Buckner made a decision in early 2019 to transition the primary care portion of his practice to a concierge medicine 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.

Dr. Buckner continues to see hematology patients in a traditional care model.  His hematology focus is on non-malignant diseases; anemia, bruising, thrombosis in general and impacting fertility, other coagulation problems, and cell number abnormalities.

He believes in effective communication and collaboration with his patients. Dr. Buckner seeks to determine an approach and treatment plan that are in the patient’s best interest, and have their full acceptance and understanding. He has strong relationships with a wide circle of preferred specialists throughout the city to whom he can refer. He has developed expertise in pain control, and treats a limited number of patients suffering from opiate addiction – adopting an individualized approach.

In 1978 he became a doctor of medicine at the Icahn School of Medicine at Mount Sinai.  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 Society of Addiction Medicine.  He has been named the Clarence Haskell Scholar by the Leukemia Society of America.
