Compassionate mental health care at South Texas Mental Health Associates San Antonio

PTSD & Trauma Therapy in San Antonio

Our San Antonio psychiatrists and therapists specialize in treating post-traumatic stress disorder and trauma-related conditions using evidence-based approaches. Whether you are experiencing symptoms from a single traumatic event, complex childhood trauma, or military service-related PTSD, our team provides compassionate, individualized care.

We utilize trauma-focused psychotherapy methods including EMDR, cognitive processing therapy (CPT), and cognitive behavioral therapy (CBT) alongside careful medication management. San Antonio is home to a large military community with Lackland Air Force Base and Fort Sam Houston nearby, and our team has extensive experience working with veterans and active-duty service members experiencing trauma-related mental health conditions. Learn more about our PTSD treatment services.

EMDR Therapy in San Antonio

EMDR (Eye Movement Desensitization and Reprocessing) is available at our San Antonio clinic as part of our comprehensive psychotherapy services. EMDR is a specialized, evidence-based treatment that helps the brain reprocess traumatic memories, reducing the emotional intensity associated with past experiences.

Our San Antonio therapists use EMDR to treat PTSD, anxiety disorders, phobias, grief, and other trauma-related conditions. EMDR is recognized by the American Psychological Association, the World Health Organization, and the Department of Veterans Affairs as a frontline treatment for trauma. Sessions typically last 60 to 90 minutes and most patients begin to experience relief within 6 to 12 sessions.

Couples Therapy & Marriage Counseling in San Antonio

Relationships require ongoing effort, and sometimes professional guidance can help you and your partner rebuild communication, resolve conflict, and strengthen your connection. Our San Antonio therapists offer couples therapy and marriage counseling using evidence-based approaches including Emotionally Focused Therapy (EFT) and the Gottman Method.

Whether you are navigating communication breakdowns, trust issues, life transitions, or considering separation, our licensed therapists provide a safe, structured environment for both partners to be heard. We work with married couples, engaged couples, and unmarried partners at every stage of their relationship. Visit our dedicated couples therapy page to learn more about our approach.

Bipolar Disorder Treatment in San Antonio

Our board-certified San Antonio psychiatrists provide comprehensive bipolar disorder treatment including accurate diagnosis, medication management with mood stabilizers and atypical antipsychotics, and ongoing psychiatric monitoring. We understand that bipolar disorder requires precise medication adjustments and consistent follow-up to maintain stability.

We treat Bipolar I, Bipolar II, and cyclothymic disorder, working closely with each patient to minimize mood episodes while managing medication side effects. Our integrated approach combines psychiatric medication management with supportive psychotherapy. Learn more on our bipolar disorder treatment page.

ADHD Treatment in San Antonio

Our San Antonio psychiatric team offers comprehensive ADHD evaluation, diagnosis, and treatment for adults and adolescents. Many adults with ADHD go undiagnosed for years, struggling with focus, organization, time management, and impulsivity without understanding the underlying cause.

Our psychiatrists conduct thorough evaluations to accurately diagnose ADHD and differentiate it from conditions with similar symptoms. Treatment may include stimulant medications, non-stimulant alternatives, and behavioral strategies tailored to your daily life and goals. Learn more about ADHD treatment at STMHA.

DBT Therapy in San Antonio

Dialectical Behavior Therapy (DBT) is a specialized form of cognitive behavioral therapy that teaches practical skills for managing intense emotions, improving relationships, and reducing self-destructive behaviors. Our San Antonio therapists are trained in DBT and apply this approach to treat borderline personality disorder, chronic depression, anxiety, and emotion dysregulation.

DBT focuses on four core skill areas:

  • Mindfulness
  • Distress Tolerance
  • Emotional Regulation
  • Interpersonal Effectiveness

Our therapists integrate DBT skills into individual therapy sessions to help you build a life worth living.
