The Immune Deficiency Foundation has announced the appointment of Dr. Paula Henao as its new medical director. In this role, she will oversee the organization’s research program and provide a key voice in clinician education and public policy initiatives.
“Paula brings exactly the leadership we need at this exciting juncture in our organization's growth,” said Jorey Berry, President & CEO. “Her clinical expertise, combined with her unwavering dedication to accessible care, positions us to make an even greater difference in the lives of individuals and families affected by primary immunodeficiency (PI). We're confident her vision for bridging research and practice will strengthen our impact for years to come.”
Henao, an associate professor of allergy, asthma, and immunology at Penn State Health Milton S. Hershey Medical Center, has a longstanding relationship with the Immune Deficiency Foundation. Prior to her appointment as medical director, she played a pivotal role in the Project ECHO (Extension for Community Health Outcomes) clinician education series—a collaboration between Project ECHO at Penn State College of Medicine and the Immune Deficiency Foundation. The ten-session virtual series helped providers recognize the signs of primary immunodeficiency and take timely steps toward diagnosis.
“I'm honored to join the Immune Deficiency Foundation as medical director at such a pivotal moment for clinical immunology,” Henao said. “Through my work with the Project ECHO series, I've seen firsthand the organization's remarkable impact on improving diagnosis and empowering patients through education. In this new role, I'm committed to translating complex immunologic research into practical solutions that address the real-world challenges our community faces every day. Together, we'll work to dismantle barriers to care and ensure safer, more equitable outcomes for everyone living with an immune deficiency."
Throughout her career, Henao has been deeply engaged in medical education and is recognized for her dedication to mentorship, communication, and humanistic practice. Her commitment to excellence has earned her multiple honors, including the prestigious Leonard Tow Humanism in Medicine Award.
A graduate of Wesleyan University (BA) and Perelman School of Medicine at the University of Pennsylvania (MD), Henao completed both her internal medicine residency and allergy & immunology fellowship at Penn State Milton S. Hershey Medical Center and is board-certified in internal medicine and allergy, asthma & immunology.
Primary immunodeficiencies (PIs), also known as inborn errors of immunity (IEI), are a group of more than 550 rare, chronic conditions in which part of the body's immune system is missing or does not function correctly. According to the National Institutes of Health, there are approximately 500,000 individuals in the U.S. with a PI. These conditions are caused by hereditary genetic defects and can affect anyone, regardless of age, gender, or ethnicity. PI can cause infection, malignancy (cancer), allergy, autoimmunity, autoinflammation, or any simultaneous combination of these issues.
The Immune Deficiency Foundation is the largest primary immunodeficiency (PI) patient advocacy group in the United States, with 44 years of expertise in primary immunodeficiency. As such, we take pride in helping to connect, engage, and empower families to live longer, stronger, healthier lives.
