Specialized Care for Children, Teens, & Adults
Eating Disorder, OCD & Anxiety Treatment in Houston, Texas & Across the US
Not all therapy is the same. When treatment hasn’t worked, structured, targeted care creates real change.
What We Treat
We specialize in the treatment of eating disorders, OCD, anxiety, and related disorders across children, adolescents, and adults.
Eating Disorders: Anorexia, ARFID, Bulimia, and Binge Eating Disorder
Obsessive-Compulsive Disorder (OCD)
Anxiety Disorders: Social Anxiety, Panic, Agoraphobia, Phobias, Generalized Anxiety, and Separation Anxiety
Post-Traumatic Stress Disorder (PTSD)
Oppositional Defiant Disorder (ODD)
Longstanding Emotional and Behavioral Patterns
Many of the individuals and families we work with are navigating complex or co-occurring conditions, including OCD and eating disorders, perfectionism, and longstanding patterns that have not responded to prior treatment.
A Higher Standard of Care
We provide specialized treatment grounded in the most effective, research-supported approaches available.
- Our clinicians have experience treating patients across the full continuum of care, from outpatient therapy to more intensive settings, allowing us to effectively work with both straightforward and complex presentations.
- This is not open-ended supportive therapy. Treatment is active, structured, and focused on meaningful change.
- We collaborate closely with families, physicians, and dietitians to ensure coordinated, effective care.
- We also offer specialized parent coaching for eating disorders grounded in Family-Based Treatment (FBT), helping families to navigate meals, resistance, and recovery at home between sessions.
A Clear, Structured Approach to Treatment
We take a formulation-driven approach, identifying the specific factors maintaining each individual’s symptoms and targeting them directly.
Treatment may include:
- CBT-E, FBT, or CBT-AR for eating disorders
- Exposure and Response Prevention (ERP) and SPACE for OCD and anxiety
- Prolonged Exposure (PE) and Cognitive Processing Therapy (CPT) for PTSD
- DBT, RO DBT, Schema Therapy, and CBASP when emotion dysregulation, overcontrol, persistent depression, or longstanding patterns are contributing factors
- Parent Management Training (PMT) for behavioral challenges and parent-based interventions
Without directly targeting these maintaining processes, symptoms often persist, even when insight is high.
Our goal is to provide each patient with a clear, structured path forward.
Outpatient & Intensive Treatment Options
We offer both standard outpatient therapy and higher-intensity treatment options, including in-home and high-frequency care.
Our intensives are designed to:
- Create rapid momentum when progress has stalled
- Provide a higher “dose” of evidence-based treatment
- Support individuals and families navigating more severe symptoms
Rather than waiting to begin treatment, we use an accelerated intake, an extended first session that moves beyond assessment to immediately begin psychoeducation and establish a clear, structured plan.
This allows us to match the level of care to each individual’s needs, rather than forcing a one-size-fits-all approach.
For some, weekly therapy is appropriate.
For others, a more immersive approach is what creates meaningful change.
Education & Consultation
We provide training, consultation, and outreach to clinicians, schools, medical providers, and families.
Our goal is to make practical, evidence-based strategies accessible, whether you’re treating a complex case, supporting a student, or navigating recovery as a family.
