Does This Sound Like You or Your Child?
Whether you are a parent searching for proactive answers or an adult trying to understand a lifetime of frustration, your struggles are valid.
We provide highly individualized testing for:
Children & Teens
Struggling with focus in the classroom, missing assignments, or needing formal testing for school support, IEP/504 planning, and academic accommodations.
College Students & Young Adults
Feeling overwhelmed by heavier academic workloads, struggling to transition to independent living, and seeking campus support or testing accommodations.
Professionals & Adults
Battling chronic burnout, intense procrastination, masking, and feeling like you have to work twice as hard as everyone else just to keep up.
Finding the Root Cause
Struggling to focus, sustain attention, or stay organized doesn't look the same for everyone. Because executive functioning difficulties heavily overlap with a complex variety of underlying cognitive, academic, and emotional profiles, a simple symptom checklist or a rushed online quiz is simply insufficient. Your unique history deserves a much more rigorous, thoughtful look than an automated screening can provide.
We are deeply committed to diagnostic precision. Our goal is never to overdiagnose or underdiagnose, but to identify the exact right answer for your specific situation. Through a comprehensive, 360-degree evaluation of your attention and processing style, we ensure you or your child walk away feeling truly seen, validated, and armed with a clear, practical blueprint for the future. (As a comprehensive diagnostic center, we also evaluate a wide range of other neurodevelopmental and cognitive profiles. Learn more about our dedicated Autism Evaluation pathway.)
Rigorous Science. Genuine Care.
Regional Leadership & Elite TrainingYou aren't just seeing any clinic—you are working with recognized leaders in the field. Director Dr. Allen Sung serves as the Vice President of the San Gabriel Valley Psychological Association (SGVPA), leading a dedicated team of specialists trained at premier clinical and academic institutions like UCLA, NYU Langone Health and Rutgers University.
01
No Long WaitlistsDon't wait half a year for clarity. As a private practice, we prioritize unhurried, attentive care and typically have the clinical availability to begin the evaluation process within a few weeks.
02
A Culture of Kindness, Warmth & RespectWe believe that premier clinical science is meaningless without genuine empathy. From your very first phone call to your final feedback session, you will be treated with deep respect, warmth, and hospitality. We pride ourselves on creating an inviting, supportive environment where you feel genuinely cared for every step of the way.
03
Clear Pricing, No Surprises.
Comprehensive assessment packages start at $4,900. Because we do not use a generic, "one-size-fits-all" approach, your exact investment will be confirmed based on clinical complexity and specific diagnostic scope required for your case.
The Investment
We operate as an out-of-network private practice. For patients wishing to seek reimbursement from their insurance, our care team can provide an itemized "superbill" upon request, complete with the specific diagnostic codes required by PPO insurance carriers.

THE COMPREHENSIVE EVALUATIONA collaborative process involving detailed clinical interviews followed by personalized, in-person testing at our Pasadena office. To ensure absolute diagnostic precision, we look beyond surface-level symptoms to evaluate the whole person, measuring integrated cognitive, executive, academic, and neurobehavioral functioning.
THE ROADMAP & PRESENTATIONOur process concludes with a warm, professional feedback session where your doctor translates dense clinical results into practical, accessible insights. Following this discussion, you will receive your formal, comprehensive written report (delivered in approximately two weeks). While final approval always rests with the individual institution, our reports are meticulously structured to meet the rigorous criteria required to advocate for school accommodations (IEPs/504 plans), university support, or high-stakes testing adjustments.

Frequently Asked Questions
-
Public school evaluations are strictly designed to determine if a child qualifies for special education services (like an IEP) within that specific district; they do not provide a formal clinical medical diagnosis. Our private ADHD evaluations provide a comprehensive medical-grade diagnosis, investigating all overlapping factors (like anxiety or learning differences) to deliver an objective roadmap universally recognized by schools, universities, and workplace HR departments.
-
We pride ourselves on having no long waitlists. From your initial intake consultation to your final feedback session, the complete evaluation process typically takes 4 to 6 weeks. Following your feedback session, your formal, comprehensive written report will be delivered within an additional two weeks.
-
Our ultimate goal is never to label; it is to illuminate. We understand that receiving diagnostic answers can stir up a complex mix of emotions. While many individuals feel deeply validated and relieved to finally understand the "why" behind their struggles, it is completely natural to also feel a sense of uncertainty. We operate from a warm, strengths-based perspective—holding space for all of these natural reactions while providing a gentle, supportive roadmap to make daily life more rewarding.
-
We regularly provide comprehensive ADHD evaluations for college students, graduate students, and working professionals. ADHD manifests differently at different stages of life—often showing up as chronic burnout, intense procrastination, or exhausting "masking" in adults. Our testing batteries are specifically tailored to look past lifetime coping mechanisms to capture your true baseline executive functioning profile.
-
This is a crucial clinical question that we will discuss in detail during your intake appointment. In some cases, we want to test baseline functioning without medication; in others, we want to measure exactly how well the current treatment is supporting your focus and executive functioning. Please maintain your usual routine until we establish a specific, customized plan during your intake meeting.
