“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?

If you’re navigating ADHD or other mental health challenges, you have options. At Mentavi Health / ADHD Online, we assess what works for you. 
Some may start with non-medicated approaches like coaching or therapy.  In other cases, patients may explore medication treatment paths when warranted by diagnosis. For some diagnosed with ADHD, the treatment clinician may work with the patient to determine if stimulant approaches work best for them. Stimulant approaches are certain medications under medical treatment that are generally Class II controlled substances. Non-stimulant options are another approach that can work for many.  Medication approaches can be used in tandem with coaching or therapy. 
 
The key is starting with our diagnostic evaluation, which is reviewed by a qualified healthcare professional. Getting clarity on what you’re experiencing is the first step toward feeling more in control. From there, you and your treatment team can determine the best path—whether that’s coaching, therapy, medication, or a combination that works for your life. 
 
If you’re not feeling right, let us walk alongside you by starting with the diagnostic evaluation.
