Dr. Ranjit Nair founded The Lung and Sleep Center of North Texas in 2012. The Fort Worth native returned to his roots, after years of extensive training and experience, to establish a practice where he can devote the extra time required to develop a relationship with his patients and create a highly personalized and specific care plan based on their individual needs.
In 2013, Dr. Nair became one of the first physicians in the Dallas-Fort Worth area to enter in the cutting edge field of interventional pulmonary medicine, a minimally-invasive method of diagnosing and treating lung disorders. Through the use of advanced techniques such as endobronchial ultrasound, patients are often able to receive a diagnosis without undergoing major surgery.
Dr. Nair pursued his various specialties to focus on the diagnostic challenges of patients with high acuity conditions and to focus on the long term treatment of patients with chronic conditions. Dr. Nair strongly believes that the doctor-patient relationship is essential to successful medical outcomes.
Dr. Nair comes from a family of physicians. His mother, father and uncle have practiced medicine in the Dallas-Fort Worth area for the past several decades. Outside of work, Dr. Nair enjoys spending time with his wife, son and daughter. His hobbies include reading, traveling, scuba diving, and supporting his favorite team, the Dallas Cowboys.
