How to book an appointment
New patients are welcome, and in most cases you can come straight to us without a referral from your primary care doctor or pediatrician. A few insurance plans do require one, so ask about your plan when you call.
- Call us at (909) 225‑1900 — best if you or your child has symptoms right now or you’re not sure what kind of visit you need.
- Ask your doctor to send a referral if your plan requires one.
What to have handy when you book
Five minutes of prep makes the first visit noticeably more useful. Having these at hand when you call helps us plan the right visit, including whether testing can be done at the first appointment.
- Your insurance card and the patient’s date of birth.
- A short history of reactions — what happened, how fast, how long it lasted, and what you did.
- A list of current medicines, including anything over the counter.
- Your primary care doctor’s or pediatrician’s name.
There’s more detail on what to expect — including when to pause antihistamines before testing — on our new patients page.
If this is an emergency, don’t wait for us
Trouble breathing, swelling of the lips or tongue, repeated vomiting after eating, sudden widespread hives, or someone who seems faint or floppy can signal anaphylaxis. Use the epinephrine auto-injector if you have one and call 911. Epinephrine first, then the hospital — always. Call us afterwards and we’ll help with what comes next.
