A complete ADHD evaluation for children, teens, and adults, conducted and signed by a psychologist. Testing available at my downtown Santa Ana office or entirely online from home. You leave with a full written report you can hand to a school, an employer, or a prescriber. One flat fee of $1,250, start to finish.

“Most people who come to me for ADHD testing have already spent years wondering. What they have never had is a real answer from someone qualified to give one.”
I'm a psychologist with more than ten years of experience, and I provide ADHD evaluations for children, teens, and adults. Parents seeking answers about a struggling student and adults who have wondered for decades go through the same rigorous process, adapted to age. I conduct and sign every evaluation myself.
A psychologist holds a doctorate, the highest level of clinical training in mental health, with advanced study in assessment, psychopathology, and diagnosis. That is what an institution looks for when it reviews your documentation, and it is what separates a real evaluation from a screening questionnaire.
Schedule Your Free ConsultationADHD rarely announces itself. More often it looks like a pattern nobody has connected yet:
If any of that lands, this evaluation was built for exactly what you are describing.
Four components make up the assessment. Together they meet accepted diagnostic standards, which is why the resulting report carries weight with schools, employers, and prescribing providers.
A structured diagnostic interview covering developmental history, school and work history, sleep, mood, anxiety, and how attention actually shows up day to day
A computer-administered measure of sustained attention, impulsivity, vigilance, and reaction time consistency, producing objective performance data rather than self-report
Normed forms completed by you and, where appropriate, a parent, teacher, partner, or close friend. Cross-informant ratings are a core part of accepted diagnostic practice
Report cards, standardized test scores, prior testing, IEP or 504 documentation, and teacher notes, reviewed and incorporated into the findings
ADHD is not the only condition that makes it hard to focus. Anxiety, sleep problems, learning disorders, depression, and thyroid issues can all produce the same complaint. A careful interview is what separates a real diagnosis from a guess. Ruling things out matters as much as ruling things in.
Orange County families should not have to sit on a six-month waitlist or drive to Los Angeles for an appointment. You have two options. Both cover the same evaluation, and both cost the same $1,250.
A quiet, private testing office in downtown Santa Ana, central enough that most of the county is a short drive rather than a freeway expedition. No waiting room clipboard, no clinic bustle, and the testing done in a single visit.
106 W 4th Street, Third FloorThe same evaluation runs over a secure, HIPAA-compliant telehealth platform. You need a computer with a webcam, a stable connection, and a quiet room. For children, a parent stays nearby to help with setup.
Attention testing measures how you perform under ordinary conditions, and an unfamiliar office at eight in the morning is not ordinary conditions for most people. For a lot of families, home is the better testing environment, not a compromise.
Serving families across Orange County: Santa Ana, Orange, Tustin, Costa Mesa, Irvine, Anaheim, Garden Grove, Fullerton, Westminster, Fountain Valley, Huntington Beach, Newport Beach, Villa Park, Yorba Linda, Placentia, Brea, Lake Forest, Mission Viejo, and the surrounding communities.
Here is the whole process, from first call to finished report. Every step below is covered by the $1,250 fee.
We talk about what is going on, what you are hoping to find out, and whether a full evaluation is the right next step. If it is not, I will tell you that. You are also welcome to ask what the report will and will not do for your specific situation.
I send secure links to your rating scales and intake paperwork, which you complete online at your own pace. Observer forms go directly to your rater by email, so a teacher form arrives in an inbox instead of going home in a backpack. Upload any records you have: report cards, prior testing, IEP or 504 documents, provider notes.
We start with the clinical interview. For children and teens, I interview parents in depth and speak with the child directly at a level that fits their age. For adults, we cover your own history from early childhood forward, since the diagnostic criteria require it. Then you complete the Conners CPT, either at the Santa Ana office or on your own machine while we stay connected. We take the time the evaluation needs. The fee does not change if it runs long.
I score and interpret everything, then deliver the written report electronically. We review the findings together on a follow-up call so you understand what the scores mean and what to do with them. No waiting weeks to hear back, and no one-page letter.
You receive a complete written evaluation documenting the referral question, the measures administered, your scores with normative comparisons, diagnostic findings under current DSM criteria, and specific recommendations. It is written to be usable by the people who will read it.
A word of honesty about what a report can and cannot do. Thorough testing gives you strong, well-supported documentation. It does not obligate a school or employer to grant a specific accommodation, and no ethical provider can promise you a particular diagnosis before the evaluation is complete. What I can promise is real testing and a report that holds up.
ADHD evaluation is billed as private pay and is not submitted through insurance. One price, quoted up front, with nothing added later. You are not paying by the hour, so a longer interview or a second testing session never costs you more.
Everything below is included. No hourly billing, no per-test charges, no separate report fee, and no surprise invoice at the end.
If you are experiencing financial hardship, please reach out. I am glad to discuss other payment options. Many clients are able to use HSA or FSA funds, and a superbill can be provided on request for possible out-of-network reimbursement.
Psychological and diagnostic evaluation sits squarely inside a psychologist's scope of practice. That means years of supervised training in test administration, normative interpretation, and differential diagnosis, which is the part that matters most here. Attention problems have a long list of possible causes, and telling them apart is the whole job.
It also means the person reviewing your documentation, whether that is a university disability office, a testing board, or a prescriber, sees a credential they recognize. I conduct and sign every evaluation myself. Nothing is handed off to a technician.
Assessment appointments in Southern California routinely book out half a year, and many practices only test children. Adults, teens, and kids are all seen here, usually within weeks rather than seasons.
For ADHD assessment, yes. The measures are the same, the norms are the same, and the interpretation is the same. Children often test better in a familiar room than in a strange building, and parents skip the drive and the missed school day. Choose whichever setting fits your family.
Yes. It covers the intake paperwork, the rating scales, the clinical interview, the Conners CPT, the records review, all scoring and interpretation, the written report, and the call where we go through the findings together. There is no hourly billing, no per-test charge, and no separate fee for the report. If the evaluation takes longer than expected, the price does not move.
Both. Children, teens, and adults all go through the same rigorous process, adapted to age. For adults, we cover your history from early childhood forward, since the diagnostic criteria require evidence that symptoms were present early.
The report is written to support 504 plan and IEP consideration, and it documents everything a district team needs: measures administered, scores with normative comparisons, diagnostic findings, and specific recommendations. Districts make their own eligibility determinations, so no provider can guarantee a particular outcome, but thorough testing gives you the strongest documentation available.
No. Psychologists in California do not prescribe. What the evaluation gives you is the documented testing that prescribing physicians and psychiatric providers frequently require before they will consider starting treatment, along with a clear picture of what is driving the symptoms.
That happens, and it is a useful result rather than a wasted one. Anxiety, sleep problems, learning disorders, depression, and several medical conditions produce attention complaints that look a great deal like ADHD. Knowing which one you are dealing with is what makes the next step work.
Upload whatever records you have: report cards, standardized test scores, prior testing, IEP or 504 documentation, teacher notes, and previous provider records. For children this often carries real weight, since a paper trail going back several years shows patterns no single appointment can.
