    I believe that all people should be given care with dignity and respect in an environment that is sensitive to each person's beliefs, values and culture. Each team member, patient and family should commit to a collaborative approach in providing an environment that will promote healing of mind, body and spirit. I believe the essential parts of providing good care to you include:
    • Taking time to listen to you and answer your questions
    • Educating you about your problem and treatment options
    • Including you in the decision-making process
    • Providing a treatment plan tailored to your individual needs
    • Providing bronchial thermoplasty
