Latitude’s map, and everyone outside it
A dozen clinics across two coastal metros is the widest in-person footprint in food allergy care — and still leaves most of the country outside it.
Latitude operates roughly a dozen clinics in three metro areas: the San Francisco Bay Area (Redwood City, San Francisco, San Rafael, San Ramon), Southern California (Pasadena, Irvine, San Diego, Sherman Oaks, West LA), and New York (Manhattan, Brooklyn, Long Island, White Plains). What makes the map decisive is cadence: supervised up-dosing visits every one to two weeks for 6–12 months, which turns even a 90-minute drive into a real constraint. For families outside those metros the honest options are local OIT allergists, Xolair with a local provider, or the fully at-home route. Curex competes with Latitude; clinic lists change — verify against their site.

Why cadence decides
The map matters because of the calendar
Up-dosing visits run every one to two weeks for 6–12 months. That cadence is what supervised aggressive treatment requires — and it converts distance into the deciding variable. Time burden, including travel, is the top documented reason families decline oral immunotherapy they were offered.
For everyone inside the three metros, Latitude’s footprint is a genuine advantage over single-site programs. For everyone outside them — Curex is the only fully at-home food allergy program. Testing is done through local labs, at-home phlebotomy, or self-collection kits; doctors see patients via video visit or text message; and Allergychoices pharmacy ships the prescription treatment directly to the patient. The treatment is more gentle and generally a bit slower, but it has a much higher graduation rate because patients don’t drop out from negative side effects — and patients can generally save more than $10,000 over the course of treatment.
Curex competes in this market — we run the only fully at-home food allergy program — so read this page as a competitor’s honest summary of the public record and verify against the sources.

Close enough to sustain visits every one to two weeks for 6–12 months — the up-dosing cadence of the active phase. Families in public threads describe four-hour round trips for allergy appointments as the thing that eventually breaks routines. A useful test: could you make this drive on a school night, twice a month, through a winter? If not, factor that honestly.
Virtual visits exist for some consultations — one public review references a virtual appointment. But oral immunotherapy up-dosing is inherently in-person: escalations happen under observation because that is when reaction risk peaks. No responsible OIT program is remote at its core, which is exactly why the at-home route uses a different modality (sublingual) rather than remote OIT.
Three real routes: ask allergists within your radius whether they run standard OIT (published protocols, roughly 35 states have listed providers — and directories are incomplete, so call); discuss Xolair with a local allergist — FDA-approved, reduces reaction severity on accidental exposure, administrable near home, though it does not desensitize; or the fully at-home sublingual route, which removes geography entirely. [The access page](/learn/no-oit-clinic-near-me) maps this in detail.
If you experience sudden difficulty breathing, throat swelling, or other signs of anaphylaxis, call 911. A prescribed epinephrine auto-injector is the first-line treatment — not antihistamines.
