SAS offers a comprehensive scope of diagnostic and treatment services for all allergy & Immunology related conditions and symptoms in children and adults. For more detailed information see: Medical Conditions & Allergic Symptoms, Diagnostic Services and Treatment Options.

Persistent Cough

That nagging cough is not only bothersome to the cougher but to family members and co-workers alike.  Post nasal drip, acid reflux, and asthma singly or in combination are among the common culprits.  Our comprehensive diagnostic and therapeutic approach has a high rate of success in stopping cough and chronic throat clearing.


Nasal allergies, sinusitis and food allergies are commonly believed to be major triggers of headaches.  Recent evidence suggests that these factors may play a lesser role in chronic headaches.  Our approach is to determine which of these various triggers are playing a role in chronic headaches, augmenting traditional headache treatment.


Instead of simply focusing on the treatment of asthma symptoms, we search for and treat the root causes of airway inflammation. This not only decreases symptoms and improves quality of life, but can also help prevent the progression of asthmatic disease. Patient education is a key element in an asthma management plan. We provide the necessary tools and information needed to take control of asthmatic disease.


"He stopped the cycle of persistent and chronic sinus infections – Wow!!" -C.P., St. Petersburg, FL

Sinusitis is inflammation or infection of any of the four groups of air sinus cavities.  Often unrecognized and undiagnosed, chronic sinusitis can cause persistent postnasal drip and chronic cough for years. Left untreated, chronic sinusitis can aggravate asthma and rhinitis. Whether sinusitis is due to allergic or non-allergic causes, we treat or try to cure this disease by non-surgical means.

Allergic Rhinitis ("Hay Fever")

Patients who suffer from chronic rhinitis know that the congestion, headache and fatigue that accompany the sneezing and itching are often disabling, forcing them to be absent from school or work. Due to Florida’s climate these symptoms can often be present year-round. Using allergy testing, we strive to identify the substances that cause the allergic response. By using a combination of allergen avoidance, medication and immunotherapy, we are able to reduce the chronic symptoms and improve a patient's quality of life.


"After several attempts with different docs we were able, for the first time, to help my granddaughter with her eczema." -S.H., Tampa, FL

Also known as atopic dermatitis, eczema is one of the most common types of allergic disease in early childhood.  This condition leads to patches of dry, itchy skin. Eczema may result from a number of allergic causes. We offer a comprehensive allergy evaluation helping to identify triggers or causes of “flare-ups” allowing patients to avoid or reduce these triggers.

Hives (Urticaria)

Urticaria is a common disorder which affects an estimated 20% of the population at one time or another. Chronic hives can last for months or years and is more than just a nuisance. The itching may be severe, keeping patients from working or sleeping.  The itchy, red, swollen areas of skin can be disfiguring. We take a detailed history, looking for clues that will help pinpoint the cause of the symptoms.  Careful adjustment of medications and avoidance of triggers allows us to control hives without bothersome side effects.

Food Allergy

Although an individual could be allergic to any food, such as fruits, vegetables, and meats, they are not as common as milk, egg, nuts, (peanuts, walnut, cashews, etc.), fish, shellfish, soy and wheat allergies, which account for 90% of all food-allergic reactions.  Careful evaluation helps patients identify food allergies and intolerances. Through the use of skin testing, laboratory evaluation and oral challenges we are able to help patients accurately pinpoint the foods they should avoid.

Drug Allergy

To confirm a medication reaction, we take a careful history of symptoms and may conduct skin testing. Such tests often reveal that the medication can be taken safely. If the test is positive and the medication is absolutely necessary, desensitization can be attempted. While desensitization is considered a last resort, it can help the body learn to tolerate a drug, even if it has produced a life-threatening reaction.

Immunodeficiency Disorders

Immunodeficiency disease is characterized by low levels of antibodies and an increased susceptibility to infections.  Immune disorders can appear in children and adults. Recurring respiratory infections involving the ears, sinuses, nose, bronchi and lungs and other chronic infections may be the first sign. A complete workup for the cause of recurrent infection can lead to the discovery of a treatable immunodeficiency disorder.
