Forest Psychological Clinic is a mental health practice based in Lake Oswego, Oregon (Portland metro area). Founded and led by Dr. James Thatcher, a licensed clinical psychologist, the clinic provides evidence-based therapy and comprehensive psychological evaluations for children, teens, and adults. The team specializes in neurodiversity-affirming care – particularly Autism Spectrum Disorder (ASD) and ADHD assessments – using a one-day evaluation model that yields same-day diagnostic results for clarity and convenience. Forest Psychological Clinic’s approach is trauma-informed and strengths-based, ensuring that clients feel seen, heard, and supported throughout the process. In addition to assessments, the clinic offers therapy services for a range of mental health concerns (anxiety, depression, OCD, trauma, behavioral challenges, etc.), emphasizing individualized care and family involvement in treatment.


Services and Specialties

  • Comprehensive Psychological Evaluations: Gold-standard assessments from toddlers to seniors. Includes diagnostics for autism, ADHD, mood and learning disorders. Most results are available the same day.
  • Autism & ADHD Expertise: Thousands of evaluations completed. Evidence-based assessments with tools like ADOS-2. Strong focus on early and accurate identification.
  • Therapy Services: Individual, child, teen, family, and parent therapy. Evidence-based treatment for anxiety, depression, trauma, OCD, emotional regulation. Modalities include CBT, DBT, ACT, and more.
  • One-Day Evaluation Model: Streamlined diagnostic experience with testing, feedback, and written reports completed quickly and efficiently, often within a single day.

Psychological Evaluations
Forest Psychological Clinic offers comprehensive psychological assessments for a range of neurodevelopmental and mental health concerns. These include specialized Autism evaluations and ADHD evaluations for all ages, as well as assessments for learning disorders, emotional and behavioral issues, and more. The clinic’s unique approach provides clarity in one day – unlike traditional assessments that can take weeks or months, Forest provides same-day diagnoses in one appointment. Evaluations are thorough, integrating standardized tools (e.g., ADOS-2, cognitive and academic tests) with clinical interviews to produce precise, meaningful results and immediate feedback. Dr. James Thatcher alone has conducted nearly 2,000 psychological evaluations, making him one of the most experienced clinicians in this field. Evaluations are neurodiversity-affirming and strengths-focused, ensuring that clients receive not just a label but a deeper understanding of themselves and an actionable plan forward.

Therapy Services
In addition to testing, the clinic provides therapy and counseling services for children, adolescents, and adults facing a variety of challenges. Areas of treatment include anxiety disorders, depression, OCD, trauma, behavioral issues, and family or school-related difficulties. The therapeutic approach is highly personalized and evidence-based: clinicians draw on modalities such as Cognitive Behavioral Therapy (CBT), Dialectical Behavior Therapy (DBT), Acceptance and Commitment Therapy (ACT), mindfulness practices, and family-systems techniques, tailoring treatment to each client’s needs. Therapy at Forest Psychological Clinic is often skills-focused and collaborative – for youth, parents and caregivers are involved to strengthen understanding and support progress at home. The clinic’s philosophy is that true change is a “winding dirt road” rather than a straight path, and therapists serve as guides to help clients and families navigate forward with clarity and confidence. Clients not only learn to manage or overcome their symptoms, but also build on their unique strengths, develop coping skills, and improve relationships in their daily lives. Notably, Forest Psychological Clinic offers individual therapy, family therapy, and specialized child/teen therapy in a neurodiversity-affirming context – for example, helping autistic or ADHD teens with social skills, identity, and emotional regulation in a way that respects their neurotype.
