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.

A pulmonologist is a physician  who specializes in the field of pulmonary medicine. Pulmonary medicine is a subspecialty of internal medicine. Pulmonary medicine, or pulmonology, entails the diagnosis and treatment of diseases, conditions, and abnormalities of the lungs and cardio-pulmonary system. The cardio-pulmonary system consists of the heart, lungs, blood vessels and all organs that work together to help a person breathe, in order to take in oxygen, and oxygenate the blood.

Pulmonologists treat breathing and lung disorders, and specialize in treatment of sleep disorders, severe allergies, asthma, COPD, restrictive lung diseases and symptoms like shortness of breath, chest pain, and chronic cough.

Our office can perform in-house Chest X-rays and has full pulmonary function equipment, as well as lab supplied blood drawers.
