A few things to know before you visit.
Do I need a referral to see a chiropractor?
In most cases, no. You can book directly with any of our offices. Check your insurance plan, as some plans have their own rules.
What should I bring to my first visit?
A photo ID, your insurance card if you have one, a list of your medications and supplements, and any relevant records or imaging. Please arrive 10 to 15 minutes early to complete a short set of paperwork.
Do you treat kids and pregnant patients?
Yes. Pediatric and prenatal care are available at all three offices, using gentle techniques suited to children and supportive positioning during pregnancy. The San Diego office also offers Webster Technique care during pregnancy.
Do adjustments hurt? Can I avoid the popping sound?
Most people feel little or no discomfort. Some feel mild soreness afterward, similar to after exercise, which usually fades within a day or two. If you would rather not hear a pop, instrument-based adjustments use a light impulse with no twisting or popping. Tell your chiropractor what you prefer.
Are any offices open on Saturday?
Yes. The Spring Valley office is open Saturdays from 8:00 am to 12:00 pm. The Lake Forest and San Diego offices are closed on weekends.
