Pulmonologist & Sleep Specialist in Woodburn, VA

Millions of Americans are affected by pulmonary disorders like Asthma, COPD, and Sleep Apnea. While your primary care physician may take care of the first diagnostic tests and treatment, they may also choose to refer you to a pulmonologist — or, lung specialist— for further diagnostics or to form an in-depth treatment plan.

When you come to NOVA Pulmonary Critical Care and Sleep Associates, you’ll find a dedicated and caring team of health professionals and supporting staff committed to helping you achieve wellness— to literally breathe easy.

Our family-friendly offices contain the most up-to-date equipment and information to help diagnose and treat several lung conditions.

Pulmonary and Sleep Disorder Treatment

Some patients are surprised to learn that their respiratory system includes more than the lungs. The entire system contains your mouth, larynx, trachea, pharynx, lungs, bronchi and bronchioles, and certain muscles. Our medical team specializes in the function of the entire respiratory system, including organs and related tissues. We also address certain sleep disorders like sleep apnea.


Most PCP offices aren’t equipped to diagnose and treat respiratory disorders to the same extent as a pulmonologist’s office. Your general physician is the first step to any treatment. While their offices handle short-term illnesses like respiratory colds, they may send you to a specialist for more long-term or severe illnesses.

What Our Patients Say About Us

"Dr. Dubey has been a tremendous find for me. We relocated from Texas and I was in desperate need of a Pulmonary Specialist. He wasted no time in getting me tested, X-rays, and then on a prescription, as he diagnosed me with Asthmatic Allergens. I was elated that someone could clinch the problem and administer diagnostic care that other physicians struggled to do over the past 5 years. He is a doctor who is very proactive and his staff is delightful and personable. I highly recommend Dr. Dubey!"
