The short version

  • “Therapist” is a general term; the license tells you the training.
  • Psychologists hold doctorates and can do psychological testing; most cannot prescribe.
  • Psychiatrists (MDs/DOs) and psychiatric nurse practitioners can prescribe medication.
  • Many people see a therapist for talk therapy and a prescriber for medication, together.

The titles get confusing fast. Here’s who does what in the US.

The quick comparison

RoleTrainingTalk therapyPrescribesTypical focus
Counselor / therapist (LPC, LMHC, LMFT, LCSW)Master’s degree + supervised hours + licenseYesNoOngoing therapy
Psychologist (PhD, PsyD)Doctorate + licenseYesRarely (a few states allow it with extra training)Therapy, testing, assessment
Psychiatrist (MD, DO)Medical school + psychiatry residencySometimesYesDiagnosis, medication
Psychiatric nurse practitioner (PMHNP)Advanced nursing degreeSometimesYesMedication management
Primary care doctorMedical degreeNoYesCommon conditions, referrals

Who should I see first?

  • You want to talk things through, learn skills or work on patterns: start with a licensed therapist.
  • You’re wondering about medication, or symptoms are severe: a primary care doctor, psychiatrist or psychiatric nurse practitioner.
  • You need a formal evaluation (for example, ADHD or learning differences): a psychologist who does testing.

What about coaches?

Life coaches can be helpful for goals and accountability, but coaching is generally not a licensed profession. Coaches shouldn’t diagnose or treat mental health conditions.

How to check a license

Every state has licensing boards for counselors, social workers, MFTs, psychologists and physicians. Search “[your state] license lookup” plus the profession to verify a license and see any disciplinary actions.

Questions people ask

Can a therapist diagnose me?
Licensed therapists and psychologists can diagnose many mental health conditions within their scope of practice. Psychiatrists can as well, and they also prescribe.
Is a social worker a real therapist?
Yes. Licensed clinical social workers (LCSWs) are trained and licensed to provide psychotherapy and are one of the largest groups of therapists in the US.
