How to choose a therapist
- 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.
- Check which license they hold (for example LPC, LCSW, LMFT or RP) and look it up with the board or college that issued it.
- 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 therapist
- 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?
- Which license do you hold, and in which state or province?
- 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?

What should I do if I need help right now?
In crisis or thinking about suicide? Call or text 988 (US and Canada), any time. In an emergency, call 911. This site cannot help in an emergency.
Which therapists and counselors in Simi Valley work on weekends?
144 of 319 ranked therapists and counselors post Saturday hours and 86 post Sunday hours. The highest-ranked open Saturdays are Smash RX LLC (#2), Westlake Trauma And Resilience (#3) and New Generations Counseling Center (#4). Posted hours are office hours; many practices also offer evening or online sessions by appointment.
What Google rating do Simi Valley therapists and counselors have?
The median Google rating among 319 rated therapists and counselors in Simi Valley is 4.9★, with a median of 9 reviews. Clinicas Madera Health Center has the most, 476 reviews, and ranks #21. We adjust ratings for review count, so a few five-star reviews cannot top the list.
How does RankedPsychologists rank therapists and counselors?
Each therapist 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 therapists and counselors outside Simi Valley count in this ranking?
Yes, if they are within 15 mi of the Simi Valley city center, our service radius for therapists and counselors. 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 therapists and counselors 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 therapists and counselors in Simi Valley ranked?
Each practice gets an RP Score from 0 to 100 from 8 published factors, including its Google rating, how clearly it focuses on therapy and counseling and how close it is. Sponsored placements are shown separately and never change rank. The score does not measure treatment outcomes.
Is a licensed counselor the same as a psychologist?
No. Licensed professional counselors, clinical social workers, marriage and family therapists and, in Ontario, registered psychotherapists hold their own licenses and answer to their own boards or colleges. They provide talk therapy for many of the same concerns; formal psychological testing is usually done by a psychologist.
Can I see a therapist 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.
