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!"
