As a specialist in interstitial lung disease, I believe that partnering with the patient and the referring physician is essential to optimal care. As a pulmonary and critical care physician, I believe in a comprehensive approach to evaluation and treatment of patients who require inpatient care.

In the office, I specialize in interstitial lung disease. These are a group of over 150 lung diseases that can cause inflammation and scar formation in the lungs. Interstitial lung disease has been my primary focus for the past 25 years.

Ohio State brings an extraordinarily high level of specialty expertise in patient care and is home to the "specialist's specialists." I am very proud to have participated in the training of many of Ohio's best physicians who now practice in hospitals and communities throughout the state.

In my free time I enjoy relaxing with my family, reading and traveling. However, my favorite activity is a day of fishing on my kayak. As I always say, my equation for happiness is - a kayak plus a fishing pole equals heaven.
