Special Interests

I treat children and adults with all allergic conditions and have particular interest in food allergy and asthma. I chose to specialize in Allergy & Immunology because many of the conditions I treat are very common and their management emphasizes improving quality of life. I strive to work jointly with patients, their families, caregivers and the community to provide the education and treatment plan that best suits each individual patient. I carry a philosophy of involving my patients and their families in each step of the decision making process and ensuring that they have a solid understanding of their medical conditions.

Dr Santos was *amazing*. I have been searching for an allergist who will listen and work WITH me for over a decade and not only did I feel heard but I am confident in Dr. Santos' knowledge and ability to choose a solid treatment plan as we continue working together.
