A mental therapist, commonly called a therapist or psychotherapist, is a licensed professional trained to help people work through emotional difficulties, mental health conditions, and life challenges using structured conversation and evidence-based techniques. Therapists hold graduate degrees and complete thousands of supervised clinical hours before earning a license to practice independently.
What a Therapist Actually Does
At its core, therapy is guided conversation with a clinical purpose. A therapist helps you identify patterns in your thinking, emotions, and behavior that contribute to distress, then works with you to change those patterns or develop skills to manage them. This applies whether you’re dealing with anxiety, depression, grief, relationship problems, trauma, or simply feeling stuck.
All licensed therapists can provide psychosocial interventions (the clinical term for talk therapy), but the specific techniques vary. Some of the most common approaches include:
- Cognitive behavioral therapy (CBT): Teaches you to recognize distorted thought patterns and understand how those patterns shape your emotions and actions. It’s one of the most widely studied and commonly used approaches.
- Dialectical behavior therapy (DBT): A form of CBT designed for people who experience intense emotional responses or struggle with impulsive or self-destructive behaviors.
- EMDR: Originally developed for post-traumatic stress disorder, this approach uses guided eye movements to help the brain reprocess traumatic memories that show up as anxiety, anger, or panic.
- Somatic therapy: Focuses on physical sensations in the body, helping you recognize and release tension or “freeze” responses tied to stress and trauma.
Your therapist will typically recommend an approach based on what you’re dealing with, though many therapists blend techniques depending on what works for you.
Types of Therapists and Their Credentials
The word “therapist” covers several distinct professions, each with different training backgrounds. What they share is a master’s degree (at minimum), thousands of hours of supervised clinical experience, and a state-issued license. Here are the most common types:
A Licensed Professional Counselor (LPC) holds a master’s degree in counseling or a related field. An Licensed Clinical Social Worker (LCSW) holds a master’s in social work and completes 3,000 supervised clinical hours over a minimum of two years. A Licensed Marriage and Family Therapist (LMFT) specializes in relationship and family dynamics, also requiring a master’s degree and 3,000 supervised hours. A clinical psychologist holds a doctoral degree and is the only therapist type that typically administers and interprets psychological testing.
State licensing boards regulate all of these professions, and requirements vary by state. The key distinction most people care about: therapists cannot prescribe medication. That authority belongs to psychiatrists (who are medical doctors) and psychiatric nurse practitioners. If medication turns out to be part of your treatment, your therapist will refer you to a prescriber while continuing therapy alongside it.
What Happens in a First Session
Before your first appointment, you’ll fill out intake forms covering your background, what brought you to therapy, and sometimes standardized questionnaires about symptoms like anxiety or depression. These aren’t tests you can fail. They give your therapist a starting point and a baseline to measure progress against later. Completing them a day or two ahead of your appointment gives your therapist time to review.
The session itself centers on a psychosocial assessment. Your therapist will ask about your current symptoms, your history, your relationships, and how your struggles affect daily life. This isn’t just an administrative step. It’s a clinical conversation that helps the therapist understand where you are, offer a preliminary diagnosis if appropriate, and start building a treatment plan tailored to you. Expect the therapist to explain how they work, what confidentiality means in practice, and what the next steps look like.
How Long Therapy Takes
There’s no single answer, but research from the American Psychological Association offers useful benchmarks. About 50 percent of patients show measurable recovery within 15 to 20 sessions. Many evidence-based treatment programs run 12 to 16 weekly sessions and produce clinically significant improvement within that window.
In practice, some people prefer to continue for 20 to 30 sessions over roughly six months to achieve fuller symptom relief and feel confident they can maintain their progress independently. People dealing with multiple conditions at once, or with longstanding personality difficulties, may benefit from longer treatment in the range of 12 to 18 months. The general pattern in the research is straightforward: more sessions tend to produce better outcomes, though the biggest gains often come in the earlier weeks.
Confidentiality and Its Limits
Everything you say in therapy is confidential, with a few specific exceptions required by law. Your therapist will explain these at the start of treatment, typically in writing. The main exceptions: if there’s suspected child abuse or neglect, if you pose a serious danger to yourself, or if you pose a serious danger to someone else. Outside those situations, your therapist cannot share identifiable information with family members, employers, or anyone else without your written consent.
What Therapy Costs
Out-of-pocket therapy in the U.S. runs $100 to $250 per session as of 2025, depending on your location, the therapist’s credentials, and the type of therapy. LPCs and LCSWs tend to charge on the lower end, roughly $100 to $174 per session. Psychologists, with their doctoral-level training, typically charge $175 to $250. Couples therapy runs about 50 percent more per hour than individual sessions.
Geography matters. The most expensive states average $150 to $250 per session, while the least expensive average $120 to $130. Many therapists offer sliding scale fees adjusted to your income, and most health insurance plans cover therapy with a copay, though network availability varies. It’s worth checking whether a therapist is in-network with your insurance before booking.
Online Therapy vs. In-Person
Teletherapy has become a standard option, and research supports its effectiveness. A study comparing telehealth and in-person counseling found that both groups showed meaningful improvement in depression and anxiety scores, with low rates of worsening symptoms. The in-person group hit clinical improvement benchmarks slightly faster: around 8 weeks for depression versus 12 weeks for telehealth, and 4 weeks for anxiety versus 8 weeks. But both groups improved reliably, leading researchers to conclude that telehealth can be used to treat depression and anxiety comparably to in-person care.
Online therapy is particularly valuable if you live in a rural area, have mobility limitations, or simply find it easier to fit sessions into your schedule from home. Some people prefer the comfort of their own space; others find the physical separation of going to an office helps them shift into a therapeutic mindset. Neither format is inherently better, and many therapists now offer both.
