What made you want to join the ADHD Online team?

“Why do you work with ADHD Online / Mentavi Health?
I believe in expanding access to compassionate, evidence-based mental health care—especially for those who may have struggled for years without answers. Mentavi Health’s mission aligns with my own commitment to meet patients where they are, reduce barriers to diagnosis and support, and empower people to thrive in their personal and professional lives. The flexibility and reach of this platform allows me to serve a diverse community with the depth and attention they deserve.

Why do you specialize in helping people with their mental health conditions?
Mental health challenges are deeply personal but widely misunderstood. I’ve seen firsthand how clarity, validation, and tailored support can dramatically change a person’s path. Whether it’s ADHD, anxiety, or another condition, I’m drawn to this work because it helps people reclaim agency and make meaningful changes—not just in how they feel, but in how they live. I want each person I work with to feel seen, heard, and supported with care that’s grounded in both empathy and expertise.

Why do you feel tele-mental health care is important for access to treatment?
Tele-mental health helps close the gap between need and care. For too many people, geography, work schedules, stigma, or family demands make traditional appointments out of reach. Telehealth removes those barriers. It makes timely, high-quality mental health evaluation and support accessible from the comfort of home—while preserving the human connection that’s essential for effective care.”

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.
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.
