Jefferson Asthma Allergy and Pulmonary Associates

1015 Chestnut Street, Suite 1300, Philadelphia, PA 19107 Tel: 215-923-7685


Dear Patient,

Asthma Allergy & Pulmonary Associates was founded in 1982 as an independent allergy and pulmonary medicine practice, whose physicians were members of the medical staff of Thomas Jefferson University Hospital and held faculty appointments at Sidney Kimmel Medical College. Much has changed over the ensuing 30 plus years in healthcare.  What has not changed has been the practice’s commitment to excellence along with concern for our patients.

In recent years it has become apparent that the best way to ensure the highest quality for our patients and the caring professionals that make up our staff, now and going forward would be to strengthen our connection with Jefferson.  As of December 1, 2015 our practice is a part of the Division of Pulmonary, Allergy & Critical Care Medicine within the Department of Medicine of Jefferson University Physicians.

The Division of Pulmonary, Allergy & Critical Care Medicine at Thomas Jefferson University is well-established and has a tradition of excellence in medical education, tertiary clinical care and research and has repeatedly been listed as a top performer in the U.S. News & World Report.  We are excited to more closely align ourselves with fellow leaders in the field of pulmonary medicine and research.

We will remain in the same location, with the same staff, and with most of the same policies and procedures.  We will also continue to admit and care for patients at Thomas Jefferson University Hospital. All services will now be managed and billed by Jefferson. There will be some cosmetic changes, the staff will have new uniforms, but what will not change is our commitment to providing patients with the best care possible. 

This affiliation will give us direct access to all of Jefferson’s resources including the faculty practice’s electronic record system.  Over the next two years, we will migrate to the same EHR as the rest of the campus, further facilitating information exchange among practitioners inside and outside of our practice.  As part of Jefferson University Physicians, we also look forward to growing the allergy and immunology faculty, ensuring continuity of care for decades to come.

We hope that these changes work well for you.  We welcome your comments and the continued privilege of being your physicians.  We thank you for the trust that you have put in us, and look forward to our continued relationship as Jefferson Asthma Allergy and Pulmonary Associates.

Best regards,


John R. Cohn, M.D.

Donna D. Carstens, M.D.

Shirley M. Fung, M.D.

Influenza (The Flu)

The doctors and nurses at AA&PA are carefully monitoring issues concerning seasonal flu. The Centers for Disease Control and Prevention recommends:

There are everyday actions people can take to stay healthy.

  • Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.
  • Wash your hands often with soap and water, especially after you cough or sneeze. Alcohol-based hands cleaners are also effective.
  • Avoid touching your eyes, nose or mouth. Germs spread that way.

Try to avoid close contact with sick people.

  • Influenza is thought to spread mainly person-to-person through coughing or sneezing of infected people.
  • If you get sick, CDC recommends that you stay home from work or school and limit contact with others to keep from infecting them.
