Identifies environmental, food, and drug triggers.
Allergen immunotherapy (allergy shots & SLIT)
Disease-modifying treatment for allergic rhinitis and asthma.
Food allergy oral immunotherapy (OIT)
Carefully escalated dosing for peanut and other food allergies.

By the numbers
Updated September 2026- Approximately 50 million Americans experience various types of allergies each year, maintaining high demand for diagnostic skin and blood testing (AAFA, 2026).
- Nearly 5.6 million U.S. children are affected by food allergies, driving a 15% increase in Oral Immunotherapy (OIT) consultations since 2024 (ACAAI, 2026).
- Over 25 million Americans have asthma, with biological therapies showing a 20% year-over-year growth for severe, eosinophilic cases (AAAAI, 2026).
- Sublingual Immunotherapy (SLIT) now accounts for nearly 25% of all new immunotherapy starts due to its needle-free, at-home convenience (ACAAI, 2026).
Trending this month: Patients are increasingly opting for asthma biologics and sublingual immunotherapy (SLIT) in 2026, seeking long-term remission and at-home treatment options over traditional weekly office-based allergy shots.
How to choose the right specialist
Verify board certification, ask how many of your specific procedure the clinician performs each year, and review patient outcomes — not just star ratings. A allergists provider who clearly explains your options, the evidence, and the realistic recovery timeline is worth more than the most heavily advertised name.
