How to choose a neuropsychologist
- Check the license with the state or provincial board that issued it; most boards publish a free online lookup.
- Make sure neuropsychological evaluation is a regular part of their work, and ask what approach they use and why.
- Ask whether your insurance needs a referral or prior authorization for testing.
- Ask how long it takes to receive the written report and whether a feedback session is included.
- Ask about fees, insurance and the cancellation policy before the first session. In the US, if you are uninsured or paying yourself, you can ask for a good faith estimate of expected charges.
- Check practical fit: in-person or online sessions, evening times, and how soon they have an opening.
- After a few sessions, ask yourself whether you feel heard. Changing to a different provider is common and fine.
Questions to ask a neuropsychologist
- Are you accepting new clients, and how soon could I start?
- Which license do you hold, and in which state or province?
- How much of your work is neuropsychological evaluation?
- Do you hold board certification in clinical neuropsychology?
- What do you charge per session, and do you take my insurance or provide a superbill?
- Do you offer online sessions?
- What is your cancellation policy?
- What do you keep confidential, and when would you have to share information?

How does RankedPsychologists rank neuropsychologists?
Each neuropsychologist gets a 0–100 RP Score from eight published factors, led by reputation (25%), specialty focus (25%), proximity (15%) and availability (10%). A practice with no Google reviews scores zero on rating, review volume and recency; other factors we cannot measure are left out. Only practices with a confirmed specialty and 3 or more reviews, or a claimed profile, are ranked.

Yes, if they are within 50 mi of the Simi Valley city center, our service radius for neuropsychologists. Each listing shows where the practice is based and how far away it is. Proximity is 15% of the RP Score, so a nearby practice gets a small edge.

How are neuropsychologists in Simi Valley ranked?

What is a neuropsychological evaluation?
A set of standardized tests of memory, attention, language, problem-solving and other thinking skills, together with interviews and a written report. It is often requested after a brain injury or stroke, when memory problems are a concern, or for complex learning and attention questions. It usually takes several hours and may be split over more than one visit.
Can I see a neuropsychologist online?
Often, yes. Licensing generally follows where you are during the session, so the provider needs to be licensed or authorized there. In the US, psychologists in PSYPACT member states can offer telepsychology to clients in other member states; counselors and social workers have their own rules. In Canada, ask whether the provider is registered in your province.
What if I need help right now?
Do not wait for a consultation. Call or text 988 (US and Canada) if you are in crisis or thinking about suicide, at any time. In an emergency, call 911.
