Dr. Alex Lechin is the Founder and acting President of the Texas Institute of Chest & Sleep Disorders, P.A. and is also a board-certified Pulmonologist. Pulmonology is an internal medicine sub-speciality focused on the health of the respiratory system as a whole.

The respiratory system includes the critical organs that allow you to breathe — a system made up of the airway, the lungs and the respiratory muscles.

Pulmonologists have expertise in treating infectious, structural, inflammatory, neoplastic and autoimmune respiratory disorders.

As a Pulmonologist, Dr. Lechin has extensive knowledge of internal medicine. He is also specialized in Interventional Pulmonology and has completed additional training in iLogic Electromagnetic Navigation Bronchoscopy System and Alair Bronchial Thermoplasty System — used for patients who are struggling to breathe due to severe Asthma.

Patients who are experiencing difficulties breathing or unusual symptoms should first see their primary care physician. After conducting a medical examination, your physician may refer you to a Pulmonologist.
