How to choose a psychologist
- Check the license with the state or provincial board that issued it; most boards publish a free online lookup.
- Make sure they regularly work with clients who have your concern, and ask what approach they use and why.
- If you may need testing as well as therapy (for example for ADHD or memory concerns), ask whether the practice does assessments itself.
- 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 psychologist
- Are you accepting new clients, and how soon could I start?
- Which license do you hold, and in which state or province?
- How often do you work with concerns like mine?
- Do you offer psychological testing, or therapy only?
- 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 psychologists?
Each psychologist 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.
Do psychologists outside Foster City count in this ranking?
Yes, if they are within 20 mi of the Foster City city center, our service radius for psychologists. 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.
Can psychologists pay to rank higher on RankedPsychologists?
No. The RP Score never reads payment status, and this ranking has 0 paid placements. Up to 3 Featured practices may appear above the list, labelled Sponsored and showing their honest rank.
How are psychologists in Foster City ranked?
Each practice gets an RP Score from 0 to 100 from 8 published factors, including its Google rating, how clearly it focuses on psychology and how close it is. Sponsored placements are shown separately and never change rank. The score does not measure treatment outcomes.
What is the difference between a psychologist and a therapist?
“Psychologist” is a protected title: only people licensed by a state or provincial psychology board may use it. Most hold a doctorate (PhD or PsyD) and are trained in psychological testing as well as therapy. “Therapist” is a general word: licensed counselors, clinical social workers and marriage and family therapists also provide therapy under their own licenses.
Can I see a psychologist 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.
