Across California, people arrive at ADHD evaluation from very different places. A parent in Fresno notices that homework takes three times longer than it should. A software worker in San Jose misses one deadline after another despite working late. A grandparent in Oxnard finally asks whether a lifelong pattern of restlessness has a name. Each story is different, and each deserves more than a checklist.
ADHD is a neurodevelopmental condition that affects attention, activity level, and impulse control. Its effects show up across school, work, and relationships, and they can look different from one person to the next. An accurate diagnosis makes it possible to build the right support: not just symptom management, but a clearer understanding of how your brain works and what helps you thrive.

Watch: How the ADHD Evaluation Process Works
A short introduction to the ADHD evaluation and counseling process at Holistic Resources Clinic.
What ADHD Looks Like in Daily Life
Attention, activity, and impulse control rarely fail in just one place. ADHD often shows up as missed steps across a whole week: a permission slip left in a backpack on the freeway, a presentation finished at midnight, a conversation that moves on before a thought is fully formed.
Signs That Often Lead Californians to Seek an Evaluation
- Symptoms that show up in more than one setting, such as home, school, and work
- Signs that began before age 12, even if they were never named at the time
- Struggles that are getting worse under new demands, like a promotion, a move, or a heavier course load
- Patterns of procrastination, lost items, or missed deadlines that do not match your effort
No single sign confirms ADHD, and symptoms like these can also come from anxiety, sleep problems, or learning differences. That is why a thorough evaluation matters.
A Customized ADHD Assessment for Every Age
There is no one-size-fits-all test. The evaluation is shaped around the person's age, history, and goals. A child's assessment looks closely at school and home functioning. An adult's assessment reviews childhood history alongside current work, study, and relationships.
ADHD in Children and Teens
For children, ADHD often appears as missed homework, trouble following multi-step directions, or big emotional swings during transitions. Some children are quiet rather than disruptive, and their attention problems are easy to overlook. Teacher and parent input are central, and early support can make a meaningful difference in school and friendships.
ADHD in Adults and Late Diagnosis
Many adults learn about ADHD only after years of compensating. Structure, effort, and strong coping habits can keep symptoms hidden until a new responsibility arrives. A late diagnosis often brings relief, and it opens the door to tools that fit the adult's actual life.
ADHD in Women
ADHD in women is frequently missed. Inattentive presentations, internal restlessness, and strong masking can look like anxiety, depression, or simply being "a lot." A thorough evaluation considers the full history and the pressures a woman has been carrying, so the picture is not reduced to a single symptom list.
The ADHD Diagnosis Process
The process is structured and transparent, and it moves at a pace you can follow. Here is what a typical evaluation includes.
Consultation
A free 20-minute call to talk through your concerns and confirm the next step.
Clinical Interview
Developmental, medical, school, and work history, plus current daily challenges.
Rating Scales
Standardized questionnaires completed by you and, where relevant, by others who know you well.
Cognitive Testing
Measures of attention, working memory, and processing speed, compared with age-based norms.
Feedback & Report
Results explained in plain language, with a written report and practical next steps.
Anxiety, learning differences, sleep problems, and other conditions are screened for during the evaluation, because several can look like ADHD. The goal is an accurate picture, not a quick label.
💡 Expert Tip Bring examples from more than one setting. Specific moments from home, school, and work help an evaluator see patterns that a single appointment cannot capture.
Meet the Psychologist Behind Your ADHD Evaluation
Dr. Stai personally conducts ADHD evaluations and provides counseling for clients across California, from the first conversation through the feedback session and any ongoing support. Her approach is trauma-informed and strengths-based, and it takes each person's story and context into account rather than relying on a single score.
Her work includes adults diagnosed later in life, women whose symptoms were overlooked, and children whose quieter presentations were missed in busy classrooms.
Treatment and Counseling After the Diagnosis
A diagnosis is the start of a plan, not the end of the process. The feedback session sets out priorities and a sensible order for next steps, which often include some combination of the following.
- Skills-based counseling, including planning, time management, and task-starting strategies
- Organizational systems that match how your attention and memory work
- School or workplace accommodations, with documentation that supports the request
- Coordination with a prescribing physician or psychiatrist if medication is considered
- Parent coaching for families, and support for adults navigating life changes
✅ Important Consideration Reports and recommendations are written for direct use by schools, employers, and other providers, including a prescriber who may be involved in your care.
Virtual ADHD Assessment: What to Prepare
Much of the evaluation can happen through secure telehealth, which means you can complete it from home, from school, or between work commitments. A few preparations make the session run smoothly.
- Choose a quiet, private space with a stable internet connection
- Test your camera, microphone, and video platform before the appointment
- Have a list of symptoms, examples, and any earlier evaluations or school reports
- Plan for breaks, and keep water and any sensory tools nearby
Some components may need an in-person or adapted format. This is confirmed during your consultation.

Costs depend on the scope of the evaluation and on whether the report and feedback session are included. Before you book, ask for a written estimate that lists exactly what is covered.

Frequently Asked Questions About ADHD Care in California

Where can I get an ADHD diagnosis in California?
Holistic Resources Clinic provides ADHD diagnosis and testing through Dr. Christina Stai, a licensed psychologist, with telehealth available to residents across California. A free 20-minute consultation is the first step.
Can a psychologist diagnose ADHD in California?
Yes. Licensed psychologists conduct ADHD evaluations using clinical interviews, rating scales completed by more than one informant, and cognitive or performance testing. Psychologists do not prescribe medication, so if medication is part of your plan, care is coordinated with a prescribing physician or psychiatrist.
How is ADHD diagnosed in children compared with adults?
In children, the evaluation looks at school and home functioning and draws on teacher and parent input. In adults, it reviews childhood history alongside current work, study, and relationships, often with a partner or family member's perspective. Both use standardized measures adjusted to age.
Can adults and women be diagnosed with ADHD later in life?
Yes. Many adults, including women, are diagnosed later in life, often because symptoms were masked, compensated for, or mistaken for anxiety or depression. A thorough evaluation looks at the full history to distinguish these patterns.
Can I get an ADHD evaluation online in California?
Much of the process, including the clinical interview and feedback session, can be completed through secure telehealth for California residents. Some components may require an in-person or adapted format, which is confirmed during the consultation.
Does this practice prescribe ADHD medication?
No. The psychologist does not prescribe medication. When medication is part of a plan, the clinic coordinates the evaluation results with a licensed prescriber of your choice.
What should I do after an ADHD diagnosis?
After a diagnosis, the next steps often include a treatment plan, skills-based counseling, organizational systems, school or workplace accommodations, and coordination with a prescriber if medication is considered. The feedback session outlines priorities and an order for next steps.
Does insurance cover an ADHD evaluation in California?
Coverage depends on your plan and whether testing is medically necessary. Holistic Resources Clinic is an out-of-network provider, and a superbill is available on request for possible reimbursement. Check your plan's out-of-network mental health benefits before your first session.
