How we ranked Rockville psychiatrists
We scored 837 Rockville psychiatrists on eight factors, weighted as shown. A practice is ranked when its specialty is confirmed and it has 3 or more Google reviews or a claimed profile.

How to choose a psychiatrist
- Check the license with the state or provincial board that issued it; most boards publish a free online lookup.
- Make sure psychiatry is a regular part of their work, and ask what approach they use and why.
- Ask whether the practice offers therapy as well as medication management, or medication visits only.
- Check whether you need a referral from your family doctor; in Canada a referral is usually required for publicly covered psychiatric care.
- 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 psychiatrist
- 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 psychiatry?
- Do you offer therapy sessions, or medication management only?
- How soon is the first appointment, and how long are follow-up visits?
- 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.

The highest-ranked open Saturdays are Adult ADHD Center with Farid Sabet MD (#7), McLean Neuropsychiatric Treatment Center (#13) and Alta C. Chery-Leonard Nurse Practitioner in Family and Psychiatry (#23). Posted hours are office hours; many practices also offer evening or online sessions by appointment.
What Google rating do Rockville psychiatrists have?
The median Google rating among 837 rated psychiatrists in Rockville is 4.6★, with a median of 14 reviews. Ali Altahir, MD has the most, 441 reviews, and ranks #31. We adjust ratings for review count, so a few five-star reviews cannot top the list.
How does RankedPsychologists rank psychiatrists?
Each psychiatrist 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 psychiatrists outside Rockville count in this ranking?
Yes, if they are within 40 mi of the Rockville city center, our service radius for psychiatrists. 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 psychiatrists 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 psychiatrists in Rockville ranked?
Each practice gets an RP Score from 0 to 100 from 8 published factors, including its Google rating, how clearly it focuses on psychiatry 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 psychiatrist and a psychologist?
A psychiatrist is a medical doctor (MD or DO) who completed a residency in psychiatry and can prescribe medication. A psychologist usually holds a doctorate in psychology (PhD or PsyD), provides therapy and psychological testing, and in most places does not prescribe. Many people see both: a psychiatrist for medication and a psychologist or therapist for talk therapy.
Can I see a psychiatrist 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.
