Meet Our Care Providers

We are a single specialty practice with a strong emphasis on disease prevention, education, accurate diagnosis of diseases and treatment of pulmonary/sleep disorders. We are also able to directly admit pulmonary patients needing inpatient care to Florida Hospital Celebration Health, ensuring high-quality care and continuity.

When you entrust your health to our care, you entrust your health to doctors who care deeply and who treat you like family.

At FLASS, we believe that compassionate communication is paramount to any successful patient/physician partnership. In our view, doctor’s compassion is the ability to actively and deeply imagine the suffering a patient is going through. We believe that you cannot meet the needs of the patients without empathizing with their suffering. Seeing ourselves as the extension of our patient’s family helps us provide reliable, compassionate and expert guidance for them and their family.
