The on-ramp at Latitude

No published waitlist exists, and — more telling — no complaint cluster about waiting appears anywhere in the public record: no long-wait threads, no petition, a BBB profile that is Not Rated with zero complaints on file. That is a genuine contrast with the destination-clinic model, where parents have described waits of a year or more. The public advice that does circulate is practical: one Bay Area parent choosing between providers wrote, "I'd go where you can get in first." The realistic expectation is ordinary specialty-clinic scheduling — intake, consult, diagnostics, then a dosing slot — with total runway varying by office and season. With roughly 12 locations across three metros, scheduling pressure also spreads across sites. Ask each office for its current timeline; nothing here is published.

Latitude publishes 6–12 months of active treatment to reach maintenance, with an average of about 8.4 months. That is the up-dosing phase — regular supervised dose escalations at the clinic. After maintenance is reached, dosing continues indefinitely: maintenance is lifelong, and Latitude offers long-term maintenance care as a service. So the honest arithmetic is under a year of intensive clinic visits, followed by an open-ended commitment to daily dosing and periodic follow-up. Families should plan for both halves, not just the first.

Latitude's own FAQ says diagnostics and visits are "typically covered" in-network, and its published insurer lists are broad — Aetna, Anthem/Blue Cross, Blue Shield, Cigna, and UnitedHealthcare appear across regions, with Health Net in California and Oxford and Empire in New York. The one-time OIT program fee is different: Latitude calls it a non-covered service, offers payment plans, notes FSA/HSA eligibility, and does not publish the amount. Patients report the figure — roughly $4,000 in the Bay Area per one Reddit account ("which they say is definitely not covered by insurance") and "over $5,000" per a New York review that called it cost prohibitive. Treat that as a range shaped by region and time, get your quote in writing at the program-design visit, and run the visit codes past your insurer for a pre-estimate before you start.

Primarily a pediatric-and-family practice, but adults have been accepted case by case. One public account describes a 36-year-old with peanut allergy who was taken on even though the clinic "stated they don't normally treat adults," with a cited eligibility threshold of a peanut component IgE of 2.0 or greater, and reached maintenance on the standard 6–12 month arc. Latitude's published outcome data also spans ages: 94% of patients of all ages achieved desensitization per its internal 2026 figures, alongside 98% for children under 4. Adults should expect an individualized screening conversation rather than a standing program, and adult OIT protocols carry extra lifestyle rules — patients mention avoiding alcohol and strenuous activity for several hours after dosing.

The standard shape: records and history, specific-IgE testing by blood and/or skin, and — where diagnosis is uncertain — supervised oral food challenges, which Latitude calls the gold standard. This step matters because a positive test alone does not equal a clinical allergy. Parents in public reviews specifically praise Latitude for challenging doubtful labels off rather than treating every positive result; one Park Slope Parents reviewer called the de-labeling "life-changing," and another wrote "I trust Latitude to be more discriminate and thorough." A challenge that rules an allergy out can end the journey before it starts — the cheapest possible outcome. One practical note from a reviewer: ask about medication holds when scheduling, since one patient reported being told to stop antihistamines before a virtual visit without advance warning.

Four moves convert runway into progress. First, gather records — prior test results, reaction history, current medications — so intake is one visit instead of three. Second, get the epinephrine action plan current and every caregiver trained; that matters regardless of which treatment you eventually choose. Third, ask Latitude for the program fee and visit billing codes, then get a written pre-estimate from your insurer — the program fee is the one number that will not be on any coverage list. Fourth, pressure-test the cadence: [what each protocol asks of a week](/learn/food-immunotherapy-daily-life) is the honest checklist, and if the fit looks doubtful or the runway stretches, ask a clinician whether starting gentler at-home treatment makes sense for your case. Sequencing is a clinical conversation, not a DIY assembly.

Latitude operates only in three metros: the Bay Area, greater Los Angeles/San Diego, and New York. Most American families live outside all three, and the wider in-person map is thin — the FAST OIT directory lists clinics in 35 states, leaving 15 states plus DC with none listed, and one Midwest study measured a median 57.3 miles to the nearest allergist of any kind. That distance problem is the documented reason most families never start clinic OIT: of 67 patients offered commercial peanut OIT in one 2022 study, 52% declined, with time burden the top reason at 28.5%. For those families the at-home route is the first choice: [Curex](/learn/how-curex-works) is the only fully at-home food allergy program, treating in every state — testing through local labs or at-home collection, doctors by video or text, drops shipped by a licensed compounding pharmacy — on gentler doses more patients finish, at $199 a month. A history of anaphylaxis or uncontrolled asthma is assessed in person first; Allergy Associates of La Crosse in Wisconsin explicitly treats those patients on sublingual drops, with one in-person first visit and virtual rechecks after. [The access geography is mapped here](/learn/no-oit-clinic-near-me).

Anyone outside a handful of coastal metros — both leading OIT clinics sit in California and New York, and the FAST directory lists no OIT clinic at all in 15 states plus DC, while Curex treats in every state from home. Families who move, travel or deploy: a clinic program ties you to one metro for the build-up year and the maintenance years after it, and drops travel in a bag. Working parents and shift workers: no fixed dosing time, generally no post-dose rest window, no clinic afternoons through build-up. Adults, whom the clinic programs are not built around. Children in sport, since OIT protocols typically ask for two to three hours without exercise after each dose and sublingual dosing generally does not. And families who could not sustain a harsher protocol — among patients actually offered peanut OIT, 52% declined, and the leading reason was time burden. A gentler course that gets completed beats a stronger one abandoned in month four. Candidacy is still clinical: an evaluation decides whether you may be a candidate, and anaphylaxis history or uncontrolled asthma is assessed in person first.
