Licensed Psychologist | Autism, ADHD, and Psychoeducational Evaluations | Children,

Teens, and Adults

Dr. Nicole McCullough, PhD

Dr. Nicole McCullough is a licensed psychologist (#4291) at Forest Psychological Clinic who rovides comprehensive autism, ADHD, learning disability, and psychoeducational evaluations

for children, teens, and adults in the greater Portland metro area.

She also maintains a small therapy caseload focused primarily on children and adolescents, bringing a warm, neuro- affirming, and trauma-informed approach to her work.

Families are often drawn to Dr. McCullough because of her ability to make the evaluation process feel less intimidating and more collaborative.

She is conversational and thorough with parents, engaging and playful with younger children, and skilled at helping teenagers feel respected and at ease. When working with adults, she creates space to explore long-standing questions and patterns without judgment.

Dr. McCullough’s goal is not simply to determine whether someone meets criteria for a diagnosis. She helps each client and family better understand how they learn, communicate, manage emotions, respond to stress, navigate relationships, and function in everyday life. Her evaluations identify strengths, support needs, and practical next steps that can make the results useful long after testing is complete.

Dr. McCullough provides comprehensive autism evaluations and ADHD evaluations for children, adolescents, and adults. Clients may seek autism testing or ADHD testing because of concerns involving attention, executive functioning, social communication, sensory differences, emotional regulation, school performance, relationships, or patterns that have never been fully understood.

For parents, an evaluation may help explain why a child is struggling despite working hard, why emotional reactions seem more intense than expected, or why social and sensory demands frequently become overwhelming. Teens may benefit from greater insight into their learning, identity, communication style, and support needs.

Adults often pursue an autism or ADHD evaluation after years of feeling different, experiencing burnout, or receiving treatment that addressed individual symptoms without explaining the larger pattern. An evaluation can help adults better understand long-standing experiences related to relationships, work, sensory needs, executive functioning, emotional regulation, and daily life.

Specialties

Depending on the referral question, testing may examine areas such as:

  • Autism-related characteristics and social communication

  • Attention and executive functioning

  • Cognitive abilities and learning patterns

  • Academic achievement

  • Emotional and behavioral functioning

  • Adaptive and everyday living skills

Dr. McCullough does not rely on a single test score or isolated behavior. She considers the person’s history, current environment, strengths, challenges, and lived experience when interpreting the results. This comprehensive approach is especially important when autism or ADHD overlaps with anxiety, trauma, depression, learning differences, or other emotional and developmental concerns. She helps clients and families understand how the different parts of the evaluation fit together, what the findings mean in daily life, and which forms of support may be most helpful moving forward.

Psychoeducational and

Learning Disability Evaluations

Dr. McCullough brings extensive psychoeducational and school psychology experience to her work. Before completing her doctoral training in clinical psychology, she earned an Education Specialist degree in School Psychology and worked directly in educational settings. This background gives her a nuanced understanding of how attention, learning, executive functioning, emotional health, developmental differences, and classroom expectations interact. It also helps her translate complex evaluation results into recommendations that parents, educators, and school support teams can realistically use.

A psychoeducational or learning disability evaluation may be helpful when a child or teen:

  • Is falling behind academically despite consistent effort

  • Shows significant differences between skills or subject areas

  • Struggles with reading, writing, or mathematics Has difficulty starting, organizing, or completing schoolwork

  • Appears capable but cannot consistently demonstrate their knowledge

  • Needs clarification regarding ADHD or a specific learning disorder

  • Requires documentation to support accommodations or educational planning

Families often enter the process with important questions. Why does school require so much effort? Why does my child understand the material at home but struggle in the classroom? Is this ADHD, anxiety, autism, a learning disability, or a combination of factors? What support

would actually make a difference?

Dr. McCullough’s reports aim to answer these questions in clear and accessible language. When appropriate, her recommendations may address classroom accommodations, learning strategies, executive functioning support, IEP or 504 planning, emotional and behavioral needs, and additional services that may benefit the student.

Her combined training in school psychology and clinical psychology allows her to consider both academic performance and the whole person behind it. She understands that learning difficulties do not occur in isolation. A child’s emotional well-being, confidence, sensory needs,

attention, and relationships can all affect school functioning.

Therapy for Children and Teens

In addition to psychological evaluations, Dr. McCullough maintains a small therapy caseload focused primarily on children and adolescents. She works with young clients experiencing anxiety, emotional regulation difficulties, school stress, adjustment concerns, stressful or traumatic experiences, and challenges associated with autism or ADHD.

Her style is warm, practical, and developmentally responsive. With younger children, she uses an engaging and playful approach to help them feel comfortable expressing themselves and learning new skills. With teenagers, she is conversational and collaborative, creating a space where they can feel respected rather than analyzed or talked down to.

Dr. McCullough recognizes that therapy for a child or teen often works best when caregivers understand what is happening and how they can help. She values parent communication and involvement when it supports treatment while also respecting the young person’s developmental need for trust, privacy, and growing independence.

She strives to provide strategies that are individualized, realistic, and useful outside the therapy room.

Neuro-Affirming and Trauma-Informed Care

Dr. McCullough’s work is grounded in neuro-affirming and trauma-informed principles. She views neurodivergence as an important part of human variation and helps clients understand themselves without pathologizing differences in communication, sensory experience, attention, emotional regulation, or learning style.

Her goal is not to make a neurodivergent person appear more typical. Instead, she helps identify the environments, accommodations, communication tools, and coping strategies that allow each person to function more comfortably and authentically.

Dr. McCullough also brings extensive trauma training to her clinical work. Her background includes military psychology roles serving active-duty service members, as well as training in evidence-based approaches such as Cognitive Behavioral Therapy, Acceptance and Commitment Therapy, EMDR, Cognitive Processing Therapy, and exposure-based treatments for trauma and anxiety.

This experience strengthens her work with children and teens who have lived through stressful or traumatic experiences. It also informs her evaluations of adults whose questions about autism or ADHD may exist alongside trauma histories, chronic anxiety, burnout, sleep difficulties, or years of working hard to cope without adequate support.

She carefully considers whether a person’s experiences are best explained by neurodevelopmental differences, trauma, emotional health concerns, learning difficulties, or a combination of factors. This attention to diagnostic overlap helps clients receive recommendations that reflect the full picture.

Collaborative and Coordinated Care

At Forest Psychological Clinic, Dr. McCullough works as part of a collaborative team that provides psychological evaluations, therapy, and medication management services. When clinically appropriate, this structure can connect diagnostic clarification with therapy recommendations, educational support, parent guidance, and psychiatric care.

Dr. McCullough values communication with other professionals involved in a client’s care, with appropriate consent. This coordination can help recommendations feel more connected and actionable while reducing the burden placed on clients and families to navigate each part of the process alone.

Education and Clinical Background

Dr. McCullough earned her PhD in Clinical Psychology from Pacific University’s School of Graduate Psychology. She also holds an Education Specialist degree in School Psychology from Brigham Young University and a bachelor’s degree in Public Health.

Her clinical training includes experience at Beale Air Force Base, Malcolm Grow Medical Center, Oregon Health & Science University, Portland Anxiety Clinic, Portland Psychotherapy, Pacific Psychology and Comprehensive Health Clinic, McMinnville High School, and Granite School District.

Earlier in her career, Dr. McCullough worked directly with autistic children and supported Spanish-speaking families in implementing strategies at home. Across these settings, her work has centered on helping people feel less overwhelmed, more understood, and better equipped with tools that fit their everyday lives.
