What Our Sterling 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!”
“We have received really great care from Dr. Dubey and his team for almost a year now. My dad’s health issues are complicated, and Dr. Dubey has really helped us achieve a better quality of life for him. He is refreshingly knowledgeable, patient, thorough, and efficient. All of the office staff is also incredibly helpful and friendly. I am so happy that we landed here and highly recommend choosing this medical group. “
