Psychiatric Nurse Practitioner ADHD California

I am a Psychiatric Mental Health Nurse Practitioner and Adult-Geriatric Acute Care Nurse Practitioner with more than two decades of experience in healthcare. I earned my Master of Science in Nursing and have been board certified and licensed as a Nurse Practitioner since 2017, with full prescribing authority and DEA registration. Prior to becoming a nurse practitioner, I practiced as a Doctor of Chiropractic, beginning my healthcare career in 2001. That early experience shaped my holistic view of patient care and my long-standing interest in helping people improve both their physical and mental performance.

Over the course of my career I have worked in hospital and outpatient psychiatric settings, including collaborating with psychiatrists in a consultation-liaison role caring for medically complex patients. While that work was meaningful, I found that I was most drawn to the outpatient setting, where I could spend more time understanding each patient’s story and helping them make meaningful changes in their daily lives. Today I evaluate and treat adults experiencing ADHD, anxiety, depression, and related conditions, with a particular focus on adults over 30 who may be seeking answers later in life.

My practice has developed a strong focus on adult ADHD diagnosis and treatment, particularly among high-performing professionals. Many of the individuals I work with are entrepreneurs, business executives, healthcare professionals, attorneys, and other driven individuals who have achieved success but continue to struggle with focus, organization, or mental overload. In many cases, ADHD was never properly evaluated or was previously misdiagnosed, and once the condition is identified and treated appropriately, patients often experience significant improvement in both work performance and overall quality of life.

My treatment approach combines evidence-based medication management with a collaborative, coaching-style conversation that helps patients better understand how their brain works. Rather than lecturing patients, I tend to ask thoughtful questions and guide self-discovery, because insight often leads to lasting change. Treatment plans are personalized and built around each patient’s goals, lifestyle, and professional demands.

My practice is based in Beverly Hills, and I work with patients throughout California via secure telehealth appointments. This allows busy professionals to access high-quality ADHD evaluation and treatment without disrupting their work schedules.

Outside of my clinical work, I enjoy spending time with my family—which can be wonderfully chaotic with four children (my wife is a saint)—and exploring great food. If I had chosen a different career path, there’s a good chance I would have become a foodie, with a particular appreciation for food trucks and Mexican street food (a guilty pleasure).

FAQ

ADHD Evaluation and Treatment – Frequently Asked Questions

Yes — and this is extremely common.

Many high-achieving professionals with ADHD have developed sophisticated coping strategies that hide symptoms for years.

You may look successful on the outside while privately dealing with:

constant overwhelm
chronic procrastination
difficulty starting or finishing tasks
mental exhaustion from trying to stay organized
feeling like everything requires twice the effort it should

In fact, many of the most capable professionals are diagnosed later in life once their responsibilities grow beyond what their coping strategies can handle.

An evaluation can finally provide clarity about what’s actually happening — and how to fix it.

Many adults with ADHD were overlooked as children — especially women.

Girls with ADHD are more likely to appear:

responsible
perfectionistic
high-achieving
quiet or internally anxious

Instead of disrupting classrooms, they often work twice as hard to keep up.

Because of this, many women are not diagnosed until their 30s or 40s when life becomes more complex with:

demanding careers
parenting responsibilities
increased cognitive workload

At that point, the coping systems that once worked stop being enough.

A proper adult ADHD evaluation is far more than a quick checklist.

Your evaluation will include:

a detailed discussion of your history and symptoms
how ADHD may be affecting your work, relationships, and daily life
screening for related conditions like anxiety or depression
evidence-based ADHD assessment tools

The goal is not simply to assign a diagnosis.

The goal is to understand how your brain works so we can create a treatment plan that actually helps.

If ADHD is confirmed, we develop a personalized treatment strategy designed to improve:

focus
productivity
mental clarity
emotional regulation
day-to-day functioning

Treatment options may include:

medication when appropriate
behavioral strategies
executive function support
lifestyle adjustments that improve cognitive performance

Many patients experience rapid improvements in focus and mental energy once the right treatment plan is in place.

No.

Medication is often highly effective, but treatment is always individualized.

Your plan may include:

medication
behavioral strategies
executive functioning techniques
lifestyle adjustments

The goal is not simply prescribing medication.

The goal is helping you function at the highest level possible.

Yes.

Many adult ADHD evaluations and follow-up visits can be completed through secure telehealth appointments throughout California.

Telehealth makes it easier for busy professionals to access care without the time and inconvenience of commuting to an office.

This is exactly why a thorough evaluation is important.

Many adults seeking ADHD assessment are actually dealing with:

anxiety
chronic stress or burnout
sleep issues
depression

A comprehensive evaluation helps determine what is really happening, so treatment addresses the root cause — not just the symptoms.

The initial ADHD evaluation typically takes about 60–90 minutes.

If ADHD is diagnosed, follow-up visits focus on:

treatment planning
medication management when appropriate
optimizing focus and daily functioning

The first step is scheduling an initial consultation.

During this visit we will:

review your symptoms and history
determine whether ADHD evaluation is appropriate
begin developing a personalized treatment strategy

For many adults, this evaluation is the moment when years of confusion finally start to make sense.

And once the right treatment is in place, many patients experience dramatic improvements in focus, productivity, and quality of life.
