There are several types of therapists, each with different training, credentials, and areas of focus. The main categories are psychologists, psychiatrists, licensed professional counselors, licensed marriage and family therapists, and clinical social workers. All of these professionals must hold a state license to practice, but they differ in education, what they can treat, and whether they can prescribe medication.
Psychologists
Psychologists typically hold a doctoral degree (a PhD or PsyD) and complete years of supervised clinical training before earning their license. Their graduate education emphasizes research, scientific methods, and all aspects of human behavior, which means they’re trained to both assess and treat a wide range of mental health conditions. Many psychologists also administer psychological testing, such as evaluations for ADHD, learning disabilities, or personality assessments, something most other therapist types don’t do.
A common question is whether psychologists can prescribe medication. In most states, the answer is no. However, 25 U.S. jurisdictions now allow specially trained psychologists to prescribe psychiatric medications. New Mexico became the first state to grant this authority in 2002, and the number of prescribing psychologists has grown from a few dozen to more than 300 today. If medication is something you think you’ll need, it’s worth checking whether psychologists in your state have prescriptive authority.
Psychiatrists
Psychiatrists are medical doctors who completed medical school and then specialized in mental health during a residency program. Their training focuses primarily on the biological aspects of mental illness, which makes them the go-to providers when medication is a central part of treatment. Every psychiatrist can prescribe medication in every state.
Some psychiatrists also provide talk therapy alongside medication management, but many focus primarily on prescribing and adjusting medications while referring patients to another therapist for regular therapy sessions. If you’re dealing with a condition that likely requires medication, such as bipolar disorder, schizophrenia, or treatment-resistant depression, a psychiatrist is often part of the care team. Expect appointments to be shorter and less frequent than with a talk therapist, especially once your medication is stable.
Licensed Professional Counselors
Licensed professional clinical counselors (often abbreviated LPCC or LPC, depending on the state) hold a master’s degree in counseling or a related field and complete roughly 3,000 hours of supervised clinical work before earning their license. They focus primarily on improving the mental health of individual patients, though many also work with couples, families, and groups.
Their scope of practice is broad. LPCCs diagnose and treat mental and emotional illness, substance abuse, personal trauma, and psychological developmental issues. Many also provide career counseling, crisis intervention, and support for adjusting to disability or major life changes. They cannot prescribe medication. If you’re looking for a therapist for general anxiety, depression, life transitions, or personal growth, a licensed professional counselor is one of the most common and accessible options.
Marriage and Family Therapists
Licensed marriage and family therapists (LMFTs) earn a master’s degree from a program specifically accredited for marriage and family therapy education, followed by about 3,000 supervised clinical hours. What sets them apart is their focus on relational and interpersonal dynamics. Rather than treating a person in isolation, they look at how relationships, family systems, and communication patterns shape someone’s mental health.
LMFTs work with couples on premarital counseling, relationship conflicts, separation, and divorce. They also treat families navigating major transitions like adoption, blended family dynamics, or a child’s behavioral issues. That said, their skills aren’t limited to relationship problems. LMFTs also address depression, anxiety, eating disorders, and other psychological conditions, but they tend to frame those issues within the context of a person’s closest relationships. If your struggles are tied to how you interact with a partner, parent, or family member, an LMFT may be a particularly good fit. They cannot prescribe medication.
Clinical Social Workers
Licensed clinical social workers (LCSWs) hold a master’s degree in social work and are fully trained to perform psychotherapy. What distinguishes them from other therapist types is their emphasis on connecting people with community resources and support services. An LCSW might help you process grief or anxiety in session, then also connect you with housing assistance, support groups, disability services, or other practical resources outside the therapy room.
This dual focus on therapy and systems navigation makes clinical social workers especially common in hospitals, community mental health centers, schools, and government agencies. They cannot prescribe medication. If your mental health concerns overlap with practical life challenges like financial stress, caregiving, or navigating the healthcare system, a clinical social worker brings a perspective that’s particularly useful.
Psychiatric Nurse Practitioners
Psychiatric mental health nurse practitioners (PMHNPs) are advanced-practice nurses with specialized training in mental health. Like psychiatrists, they can prescribe medication in all 50 states, though some states require them to work under the supervision of a physician. Many PMHNPs also provide therapy alongside medication management.
In practice, PMHNPs fill a role similar to psychiatrists, especially in areas where psychiatrists are in short supply. Wait times to see a PMHNP are often shorter, and their appointments tend to be somewhat longer. If you need both medication and therapy from a single provider, a PMHNP may be a practical choice.
Common Therapy Approaches They Use
The type of license a therapist holds tells you about their education and scope of practice, but it doesn’t tell you how they’ll actually work with you in session. That’s determined by their therapeutic approach, or modality. Most therapists across all credential types specialize in one or more of these methods.
Cognitive behavioral therapy (CBT) is one of the most widely used and researched approaches. It focuses on identifying distorted thought patterns and understanding how those patterns shape your emotions and behaviors. CBT is usually more structured than traditional talk therapy, often limited to a set number of sessions, and typically involves homework between appointments. It’s a common first-line approach for anxiety, depression, insomnia, and phobias.
Dialectical behavior therapy (DBT) is a specialized form of CBT originally developed for people who experience intense emotional responses or self-destructive and impulsive behaviors. The word “dialectical” refers to holding two opposing truths at once, helping people move out of all-or-nothing thinking. DBT often involves both individual sessions and group therapy, with a strong focus on social interactions, distress tolerance, and emotional regulation.
EMDR (eye movement desensitization and reprocessing) was initially developed to treat post-traumatic stress disorder. It works by having you recall traumatic memories while a therapist guides you through specific eye movements. This process helps your brain reprocess those memories so they no longer trigger intense emotional reactions like panic, anger, or anxiety. EMDR has since been applied to other conditions beyond PTSD, but trauma processing remains its core strength.
Psychodynamic therapy is rooted in exploring how unconscious thoughts, past experiences, and deep-seated patterns influence your current behavior and relationships. Sessions are less structured and more open-ended than CBT. This approach works well for people who want to understand recurring patterns in their lives or relationships rather than focus on a single symptom.
How to Choose the Right Type
Start with what you need. If you’re fairly certain medication will be part of your treatment, look for a psychiatrist or psychiatric nurse practitioner. If your concerns center on a relationship or family conflict, a marriage and family therapist has the most targeted training. If you need help navigating both mental health and practical life challenges, a clinical social worker is well suited. For general therapy focused on individual mental health, a psychologist or licensed professional counselor covers the broadest ground.
Beyond credentials, pay attention to the therapist’s modality and specialization. Therapists within every profession typically specialize in working with certain populations (children, adolescents, older adults) or certain issues (substance abuse, eating disorders, trauma). A licensed counselor who specializes in EMDR for trauma will look very different in practice from a licensed counselor who focuses on career transitions.
You can verify any therapist’s license through your state’s professional licensing board, which maintains searchable databases updated regularly. These tools confirm whether a provider’s license is active and whether there’s any disciplinary history on file. Most states offer free online lookup tools on their department of professional regulation website.
