About Us

Welcome to The Allergy and Asthma Centers of Cape Cod

I’m Dr. Johnson, a board-certified specialist in allergies and immunology, heading an exceptional team of healthcare professionals devoted to offering exceptional care for those dealing with allergies and asthma.

We are founded on the principle of patient-centric care, firmly believing in partnering with our patients in their healthcare journey. We leverage our exhaustive medical education and unique expertise to manage a broad spectrum of allergy and asthma conditions, ensuring you obtain the highest level of treatment.

Our pride resides in our commitment to stay ahead in allergy-immunology research. This dedication has led to revolutionary breakthroughs, such as being pioneers in diagnosing rare conditions including green tea-induced anaphylaxis, pumpkin seed-triggered anaphylaxis, bay leaf allergy, and garlic-provoked food protein-induced enterocolitis syndrome.

In my journey to push the boundaries of allergy-immunology, I have written over 20 peer-reviewed publications, added to a book chapter on asthma, and have been invited to present at more than 10 national conferences. It was a distinct privilege to present on anaphylaxis to global consulates, earning me a commendation from the Governor of New Hampshire for my contributions to the field.

My medical journey started with a fervor for research, and I was lucky to secure an American Heart Association research grant during my college years. This opportunity sparked my passion to effect change through research. I collaborated on innovative projects on tissue-engineered replacement heart valves for children with Boston Children’s Hospital, Harvard Medical School, and Massachusetts Institute of Technology. My work was featured in Circulation, a leading cardiology research journal. Subsequently, my research on Huntington’s Disease, conducted at the University of Central Florida – College of Medicine, gained recognition on the cover of Nature Medicine.

In order to remain at the forefront of our discipline, I am an active member of various prestigious organizations, such as the American Academy of Allergy, Asthma, and Immunology, American College of Allergy, Asthma, and Immunology, the New England Society of Allergy, American Association of Immunologists, Clinical Immunology Society, Society for Pediatric Dermatology, and American Contact Dermatitis Society.

At our center, our mission transcends providing expert medical care, as we strive to foster a warm and supportive atmosphere for all our patients. We strongly believe that customized care and patient education are key components of effective allergy and asthma management.

Thank you for considering The Allergy and Asthma Centers of Cape Cod as your healthcare partner. We eagerly await the opportunity to guide you towards enhanced health and an improved quality of life. Should you have any inquiries or wish to book an appointment, please feel free to reach out to us.

By operating as a team with our patients we have been able to be the first to diagnose green tea-induced anaphylaxis, pumpkin seed-induced anaphylaxis, bay leaf (spice) allergy, and garlic-induced food protein-induced entercolitis syndrome.

I am always looking for ways to further the field of allergy-immunology and by doing so I have more than 20 peer reviewed publications, a published a book chapter on asthma, over 10 invited presentations to peers, including national conferences. Also, I was fortunate to present anaphylaxis to consulates representing countries throughout the world, which was recognized with a commendation from the State of New Hampshire Governor for advancing the field of allergy & immunology.

I was very fortunate to be 1 of 8 college students in the Northeast U.S. awarded an American Heart Association research grant, which served to ignite my passion for research. My research initially focused on tissue-engineered, replacement heart valves for children at Boston Children’s Hospital in collaboration with Harvard Medical School and Massachusetts Institute of Technology. These contributions were published in Circulation, the premier cardiology research journal. Subsequently, at the University of Central Florida - College of Medicine, the research I contributed on Huntington’s Disease was published on the cover of Nature Medicine.

I hold memberships to a number of relevant organizations including, but not limited to, the American Academy of Allergy, Asthma, and Immunology, American College of Allergy, Asthma, and Immunology, the New England Society of Allergy, American Association of Immunologists, Clinical Immunology Society, Society for Pediatric Dermatology, and American Contact Dermatitis Society
