Hermosa Beach, California
ADHD Assessment & Treatment in Hermosa Beach
Comprehensive ADHD evaluation for Beach Cities professionals seeking thorough psychiatric assessment
Our Approach for Hermosa Beach Residents
Why Focus Problems Need Medical Investigation
Many Hermosa Beach residents struggle with focus, concentration, and productivity—and assume it must be ADHD. But research shows that 40% of "treatment-resistant" ADHD cases have undiagnosed medical conditions driving symptoms.
Before diagnosing ADHD, we investigate whether thyroid dysfunction, iron deficiency, sleep disorders, or other medical factors are causing your symptoms. Many ADHD-like symptoms overlap with anxiety and depression. When these underlying conditions are treated, many patients experience significant improvement—and our medication management approach ensures optimal outcomes.
With 19 years of ICU experience managing complex medical cases, I bring diagnostic rigor to psychiatric care. Your evaluation includes comprehensive lab work and medical assessment—not just a symptom checklist.

Common Questions
ADHD Evaluation FAQs for Hermosa Beach Patients
What makes ADHD evaluation at Horizon Peak Health different from other Hermosa Beach area providers?
Unlike standard ADHD assessments that rely primarily on symptom checklists, our approach includes comprehensive lab work to identify medical conditions that mimic ADHD—such as thyroid dysfunction, iron deficiency, vitamin deficiencies, and sleep disorders. With 19 years of ICU medical experience, we bring diagnostic rigor to psychiatric care, ensuring you get the right diagnosis and treatment.
How long does an ADHD evaluation take?
Your initial evaluation is 75-90 minutes. This thorough assessment includes reviewing your medical history, discussing your symptoms in detail, and ordering appropriate lab work. We don't rush through appointments—complex cases require time to investigate properly.
Do you accept insurance for ADHD treatment in Hermosa Beach?
Yes, we accept most major insurance plans including Aetna, Blue Cross Blue Shield, Cigna, and UnitedHealthcare. We recommend calling our office at (310) 955-1041 or your insurance provider to verify your specific coverage before your appointment.
Can thyroid problems cause ADHD-like symptoms?
Yes, even mild thyroid dysfunction can cause cognitive slowing, difficulty concentrating, fatigue, and brain fog—symptoms identical to ADHD. Research shows that many patients diagnosed with "treatment-resistant ADHD" actually have underlying thyroid issues. This is why we include thyroid testing in our comprehensive evaluation.
How do I get to your office from Hermosa Beach?
Our Rancho Palos Verdes office is just 10 miles from Hermosa Beach, about a 18-25 min drive. Take PCH south through Redondo Beach to Palos Verdes Blvd, continue to Western Ave south. We're conveniently located for all Beach Cities residents.
Do you work with active professionals for ADHD evaluation?
Yes, many of our Hermosa Beach patients are active professionals who need to stay focused for work while managing demanding lifestyles. We understand the unique challenges of balancing career demands with attention difficulties. Our flexible scheduling includes telehealth options for follow-ups.
Patient Experiences
What Our Patients Say
Perfect rating on Google
"Good help is hard to find. And I'm incredibly grateful that I found Canybec because he's one of the best. He instills in you a curiosity about treatment so that you yourself can get a really good sense of what meds and dose are right for you. It's as engaged as I've seen any clinician. He has reached out to me outside of sessions, giving me ideas on other things that can help. I appreciate the holistic approach that he takes. Lastly, it's incredibly clear that he actually cares. If life circumstances get hard and things aren't working for you, Canybec will work with you. He tries to find creative ways to make things as cost-effective for you as possible. Can't thank him enough for all his help."

"I usually don't leave any reviews positive or negative. But after meeting Canybec, you feel he actually cares about his patients. He always listens to you and doesn't make you feel like he's in a hurry and wants to get to the bottom of your problems. It's like it's his mission to help you resolve all your health issues. So I felt compelled to write this review and show my appreciation. I highly recommend him to anyone that needs help, you won't be disappointed."

"If you've struggled to find a quality provider, look no further. Canybec is easy to talk to, never feels clinical or scripted, and genuinely cares. He creates a safe, supportive space that's helped me grow and heal over the past year. He's also super up-to-date with the latest in mental health, so I feel like I'm learning something new every time we meet. Highly recommend!"

"Just wanted to thank Canybec for help in managing my mental health needs. After an unpleasant experience with my PCP who initially managed my mental health needs, I reached out to Canybec who was very knowledgeable, patient, and empathetic. I informed him of the side effects I was having on a certain class of medications. He explored and offered different medication and treatment options - even showing latest evidence-based practice and research for each option. Thankfully, the option I've chosen has been working great for me without the major side effects and allowed me to be functional again."
