Psychologist, Psychiatrist or Therapist: Who Does What in Colorado
Short answer
A psychiatrist is a medical doctor (MD or DO) who can diagnose, prescribe medication and provide therapy. A licensed psychologist has a doctorate and provides assessment and therapy; in Colorado, a psychologist may prescribe only with a special state prescription certificate. Therapists such as LCSWs, LPCs and LMFTs provide assessment and therapy, but Colorado law does not let them prescribe. Many people see a therapist and a prescriber at the same time.
In crisis or thinking about suicide? Call or text 988 now (in Colorado it reaches the 988 Colorado Mental Health Line). If you are in immediate danger, call 911.
This guide is not enough if
- You are in crisis or thinking about suicide. Call or text 988, or call 911 if you are in immediate danger.
- You have a question about a medication you already take. Ask the prescriber or a pharmacist, and do not change it on your own.
- You need a medical exam for physical symptoms. A physician or nurse practitioner is the right first stop.
- You want help choosing a specific therapist. The guide to finding a therapist in Denver covers fit and approach.
Why the titles get confusing
People use "therapist," "counselor" and "psychologist" as if they mean the same thing. They do not. Each title points to a different kind of training and a different set of things the person is allowed to do.
SAMHSA, the federal mental health agency, puts it simply: all of these professionals give important care, but some can prescribe medicine and some cannot. It also suggests that your primary care provider can be a good place to start, since they can often help with anxiety or depression.
The quickest way to know what someone can do is to look at their license, not their job title. The license check guide shows how to do that on DORA in a few minutes.
Psychiatrists and psychiatric nurse practitioners
The American Psychiatric Association describes a psychiatrist as a medical doctor (an MD or DO) who specializes in mental health, including substance use disorders. To get there, a person finishes medical school, passes exams for a license to practice medicine, and then completes four years of psychiatry residency.
Because they are physicians, psychiatrists can order lab tests and look at how physical and mental health affect each other. The APA says they use talk therapy, medication and other treatments, depending on the person's needs. Some people see a psychiatrist mainly for evaluation and medication, and see a therapist for weekly sessions.
SAMHSA lists psychiatric or mental health nurse practitioners alongside psychiatrists as professionals who can prescribe for mental health conditions, and notes that the rules depend on the state. Primary care doctors, nurse practitioners and physician assistants can also prescribe for many common conditions, including depression and anxiety. On DORA's lookup, these professionals appear under the Medical or Nursing license types, not the mental health boards.
Licensed psychologists, and the prescribing exception
A Colorado psychologist license requires a doctorate in psychology, at least one year of supervised postdoctoral experience, a written exam and a jurisprudence exam (C.R.S. 12-245-304). Colorado law defines the practice of psychology to include psychological testing, psychotherapy, and the diagnosis and treatment of mental health disorders. That testing can cover areas such as intelligence, personality, cognitive abilities and psychoeducational evaluation (C.R.S. 12-245-303).
Since August 2023, Colorado has allowed a narrow path for psychologists to prescribe. Under C.R.S. 12-245-309, a licensed psychologist may prescribe psychotropic medication only after earning a prescription certificate from the state board, with approval of the Colorado Medical Board. The requirements include a master's degree in clinical psychopharmacology, a national psychopharmacology exam, and a supervised practicum of at least 750 hours with at least 150 clients under prescribing physicians.
Even then, a prescribing psychologist must keep a working relationship with the patient's physician, get the physician's written agreement before prescribing, and tell the patient in writing that they are not a physician. They may not prescribe to anyone under 18 without a parent or guardian's informed consent. A psychologist without that certificate does not prescribe.
You may also meet a postdoctoral fellow or a psychologist candidate. That person has a psychology doctorate and is completing the supervised experience a license requires. Colorado reserves the plain title "psychologist" for licensed psychologists (C.R.S. 12-245-306), though anyone may list a degree they earned, such as a PhD.
| Professional | Training | Prescribes? | Usual role |
|---|---|---|---|
| Psychiatrist (MD or DO) | Medical school, a medical license and four years of psychiatry residency | Yes | Diagnosis, medication, and sometimes therapy |
| Psychiatric nurse practitioner | Nurse practitioner with a focus in psychiatry | Yes, per SAMHSA; rules vary by state | Evaluation and medication |
| Licensed psychologist (PhD or PsyD) | Doctorate, one or more years of supervised postdoctoral experience, exams | Only with a Colorado prescription certificate | Therapy, psychological testing and diagnosis |
| Licensed clinical social worker (LCSW) | Master's or doctorate in social work, at least 3,000 supervised hours, exams | No | Therapy, assessment, case management and referral |
| Licensed professional counselor (LPC) | Master's or doctorate in counseling, at least 2,000 supervised hours, exams | No | Therapy and assessment for individuals, couples, families and groups |
| Licensed marriage and family therapist (LMFT) | Master's or doctorate in marriage and family therapy, at least 1,500 hours of supervised client contact, exams | No | Therapy with a focus on relationships, couples and families |
Clinical social workers, counselors and marriage and family therapists
Many people who call themselves therapists in Colorado hold one of three licenses: licensed clinical social worker (LCSW), licensed professional counselor (LPC) or licensed marriage and family therapist (LMFT). Each requires a graduate degree, a set number of supervised hours and exams. The table below sums up the training.
Colorado law describes each of these practices as including assessment, diagnosis and psychotherapy. Marriage and family therapy is defined around the way individual problems connect to relationships, and serves individuals, couples and families. Professional counseling covers wellness, personal growth and career development as well as mental health conditions.
None of these licenses allows prescribing. C.R.S. 12-245-210 says nothing in the Mental Health Practice Act lets these professionals prescribe drugs or practice medicine. C.R.S. 12-245-211 adds that they must work with a physician for medical problems and may not diagnose or treat medical problems themselves.
When you might see two of them
It is common to have more than one professional on your side. Here are some combinations people often use:
- A therapist plus a prescriber. Weekly therapy with an LPC, LCSW, LMFT or psychologist, and medication managed by a psychiatrist, nurse practitioner or primary care doctor.
- A therapist plus a psychologist for testing. Ongoing therapy with one clinician, and a one-time psychological evaluation with a psychologist.
- Individual therapy plus a skills group. One-on-one sessions with a therapist, plus a clinician-led group such as a DBT skills group that teaches coping skills step by step.
- A therapist plus your primary care doctor. Therapy for mood or stress, while your doctor checks for physical causes of symptoms like fatigue or poor sleep.
Who to call first, and when this is not the right step
If you mainly want someone to talk with and learn skills from, a licensed therapist or psychologist is a natural first call. If you are wondering about medication, start with your primary care provider or a psychiatrist. If you are not sure, either one can help you sort out the next step. The therapy vs medication guide goes deeper on that choice.
When two professionals share your care, they usually ask for your permission, often in writing, before they talk. Questions about starting, changing or stopping a medication belong with your prescriber.
Mountainside's team page lists each clinician's credentials. The team includes a licensed psychologist, a licensed clinical social worker, licensed professional counselors and a postdoctoral fellow, and the practice's site describes therapy and skills groups; it does not list medication prescribing.

If you are thinking about suicide or feel unsafe, do not wait for an appointment. Call or text 988, or call 911.
Frequently asked questions
Can a psychologist prescribe medication in Colorado?
Only with a prescription certificate. Since a 2023 law, a Colorado-licensed psychologist can apply for one after extra training in clinical psychopharmacology, an exam and a supervised practicum with prescribing physicians. A prescribing psychologist must also work with the patient's physician and get written agreement before prescribing. A psychologist without the certificate does not prescribe.
Is a psychiatrist better than a therapist?
Neither is better in general. They do different jobs. A psychiatrist is a physician who can evaluate medical factors and prescribe medication. A therapist or psychologist usually offers regular talk therapy and skills work. Some people need one, some need the other, and many do well with both working together.
What is the difference between a counselor and a therapist?
"Therapist" is an everyday word for someone who provides psychotherapy. "Licensed professional counselor" (LPC) is a specific Colorado license that requires a counseling degree, supervised hours and exams. An LCSW or LMFT may also call themselves a therapist. Check the license on DORA to see exactly which credential someone holds.
Can my therapist and my psychiatrist talk to each other?
Yes, usually with your permission. Colorado's Mental Health Practice Act says a therapist may not share what you tell them without your consent, apart from specific legal exceptions. So therapists typically ask you to sign a release before they coordinate with a prescriber. You can ask what will be shared and limit it.
Do psychiatrists do talk therapy?
Some do. The American Psychiatric Association says psychiatrists use talk therapy, medication and other treatments depending on each patient's needs. Some people see a psychiatrist for evaluation and medication visits and a separate therapist for weekly sessions. Ask a psychiatrist's office what their visits usually include.
