Denise Loizou, RN

 

Outreach & Patient Coordinator

As a mother of children with severe food allergies, Denise was all-too-familiar with sudden life-threatening moments.  The need to educate and advocate became a compelling force that laid the groundwork for her role at Amerimmune. Denise has been working with Dr. Alpan since 2007.  She quickly discovered another passion: educating and assisting others facing chronic immune issues, whether severe allergy, Eosinophilic Esophagitis, or Primary Immunodeficiencies. Her interest and drive are compelled by the need of patients and healthcare providers to manage disorders that are often misunderstood. 

Throughout her career, Denise coordinated multi-disciplinary clinics for patients with eosinophilic disorders; she launched the first, and assisted in subsequent annual educational forums (CME events) for healthcare providers to gain a more complete understanding of immune disorders; and she has served as a liaison on behalf of iCurbConsult to the medical community. 

Denise is currently involved in expanding the reach of Amerimmune to local and national medical practitioners.  She wants to ensure doctors have a simple, reliable and beneficial means of identifying immune disorders within their practice.
