    Physician Bio

    Thank you for taking the time to consider our group and for giving us the opportunity to help with your allergy and asthma related needs. I completed my allergy and immunology training at Columbia-Presbyterian Medical Center in 1992 and have practiced in Florida ever since. I am certified by the American Board of Allergy and Immunology (ABAI) and participate in the Maintenance of Certification (MOC) program that is sponsored by the AGBAI to promote continuing medical education and to help stay current in all aspects of allergic diseases.

    Our primary goal has always been to provide honest, exceptional allergy care to patients of all ages in a caring and cost effective manner. We believe that the management of allergic disorders must be individualized to each person, and should encourage an emphasis on patient education, lifestyle modification, and prevention as key elements of long term health. We will help to establish for you, a comprehensive evaluation and treatment plan.

    We evaluate a full spectrum of allergic disorders including: nasal allergy (hay fever) sinusitis, asthma, hives (urticaria), eczema, food allergy, drug allergy, itching, stinging insect allergy and anaphylaxis. We look forward to helping you resolve any allergy related issues that you may be struggling with. I am fluent in Spanish and have a conversational knowledge of Portuguese.
