Services
Allergy Testing
Allergy testing identifies specific allergens causing symptoms through skin prick, intradermal, and patch tests. Our board-certified allergist creates personalized treatment plans based on test results. Patients receive guidance on allergen avoidance and immunotherapy options for long-term relief.
Asthma Management
Comprehensive asthma care includes diagnostic testing, trigger identification, and customized treatment plans. We offer biologic therapies, inhaler training, and allergy shots for patients with allergy-induced asthma. Our approach focuses on symptom control and preventing severe flare-ups.
Allergy Shots
Allergy shots gradually desensitize the immune system to allergens through regular injections. This treatment addresses environmental allergies like pollen, dust mites, and pet dander. Patients experience long-term symptom reduction after completing the 3-5 year maintenance phase.
Eczema Treatment
Eczema treatment combines topical medications, skin care regimens, and allergen avoidance strategies. We address underlying allergies contributing to flare-ups and offer biologic therapies for severe cases. Patients receive education on managing triggers and preventing complications.
Food Allergy
Food allergy services include diagnostic testing to distinguish true allergies from intolerances. We develop avoidance plans and prescribe emergency epinephrine for severe reactions. Patients receive ongoing monitoring and education about cross-contamination risks and label reading.

Dr. Sandhu was extremely professional and took her time to evaluate what would work best for my skin. I truly felt like she gave me the best care and results. Highly recommend for all care but especially Botox or any other aesthetics!
