Georgetown Pulmonary Associates, P.A. (GPA) was founded in 2009 on the premise of providing accessible, comprehensive pulmonary and critical care coverage to meet the growing health care demands in the Central Texas community. Our scope of practice includes the subspecialty of Interventional Pulmonology.
Dr. Esther Fields, Dr. Dominic deKeratry, Dr. Audrey Nguyen and Dr. Mandeep Mangat are all board certified Pulmonary and Critical Care specialists. Dr. Fields and Dr. deKeratry both have extensive experience in the performance of a wide-range of interventional pulmonology and pleural procedures. Dr. Mangat, our newest pulmonary and critical care physician, joined GPA in August 2017. He expands the capacity of our practice to provide state-of-the-art, evidence-based pulmonary and critical care services to our patients.
For diagnosing and treating a variety of respiratory diseases (see tab: Conditions We Treat), we offer an in-office, full service pulmonary function lab. This enables us to perform comprehensive diagnostic testing for patients with respiratory ailments.
In our office, while the patient is receiving procedural sedation and analgesia, we are able to perform diagnostic bronchoscopies and endobronchial ultrasound (EBUS). EBUS, commonly referred to as “medical mediastinoscopy”, allows us to sample lymph nodes in the chest with a minimally invasive technique. We are also able to perform chest ultrasound to evaluate pleural diseases (e.g. pleurisy, pleural effusions). The ultrasound provides a component of safety in draining pleural fluid by thoracentesis or during placement of a long-term tunneled pleural catheter (Pleur-X).
Our experienced, friendly and accommodating office staff includes registered nurses and medical assistants, as well as insurance and administrative coordinators.
