“I specialize in ADHD care because I’ve seen firsthand how life-changing the right diagnosis and treatment can be. ADHD affects every aspect of a person’s life—from work and school to relationships and self-esteem—but with proper support, patients can thrive.”

With over 30 years of clinical experience, I am dedicated to providing evidence-based, compassionate care that empowers patients to manage their symptoms effectively and improve their quality of life. My approach combines the latest advancements in ADHD treatment with a personalized, holistic strategy that considers each patient’s unique challenges and strengths. I have extensive experience in medication management to support improvements in focus, productivity, and emotional well-being. I also collaborate closely with families, educators, and mental health professionals to create comprehensive treatment plans tailored to each individual’s needs.
As an advocate for ADHD awareness and education, I am passionate about reducing stigma and helping patients unlock their full potential. Through telemedicine, I make high-quality ADHD care accessible, offering convenient, confidential consultations that fit into my patients’ busy lives.

What made you want to join the ADHD Online team?

I specialize in ADHD care because I’ve seen firsthand how life-changing the right diagnosis and treatment can be. ADHD affects every aspect of a person’s life—from work and school to relationships and self-esteem—but with proper support, patients can thrive. Through telehealth, I can provide accessible, judgment-free care to individuals who might otherwise struggle to find the help they need. My goal is to empower my patients with the tools and strategies to navigate life with confidence and success.

Curious about stimulant or non-stimulant approaches?

These terms refer to certain approaches to treat diagnosed ADHD. Mentavi Health / ADHD Online may provide stimulant approaches (certain medications under medical treatment that are generally considered Class II controlled substances) or non-stimulant approaches (medications generally not considered Class II, and/or therapy and coaching not related to medication).

A diagnosis and initial conversation with our treatment clinicians is key to the best path for you. The diagnosis is a key first step to determine if you have ADHD or other related conditions. Approximately 60% of patients with ADHD have co-occurring conditions such as anxiety or depression, for example. At the same time, patients who believe they have ADHD may not even have it. For those who do, there can be a variety of considerations into what kind of treatment works best to meet the patient where they’re at.

If you are not feeling right, your journey starts with the first step of diagnostic evaluation.

There may be a brief delay in service today between 12:30 PM and 1:30 PM ET. Thank you for your patience — we look forward to assisting you shortly.
