    Provider's Bio

    On average, we take over 23,000 breaths per day. For most, this activity is performed without second thought. However, for those with underlying lung disease, each breath can be a painstaking and anxiety-provoking task that significantly affects one's quality of life.

    As a pulmonologist, my goal is to take the time to actively listen to you and derive an evidence-based plan that is specifically tailored to your needs with the goal of improving your quality of life.

    In addition to pulmonary medicine, I get the opportunity to take care of those admitted to the Intensive Care Unit (ICU). Being admitted to the ICU can be incredibly stressful for a patient and their family. My goal is to create open lines of communication and transparency into our care plan in order to ensure everyone feels as comfortable as possible.
