I can’t say enough great things about Dr. Chappell the entire team at Collin County Pulmonary Associates. From the moment you walk in, you’re greeted with kindness and professionalism. Dr. Chappell is incredibly knowledgeable, thorough, and genuinely cares about his patients. He takes the time to listen, explain everything clearly, and ensure you feel comfortable with your treatment plan. The staff is equally amazing—efficient, friendly, and always willing to help. I highly recommend this office to anyone in need of exceptional pulmonary care!
