What our patients are saying...

NEW
“I have been with ADO/Mentavi for years. During the med shortage, life was rough got everyone, everywhere. I still got my meds consistently. I miss my original doc, but really for med mgmt l have had nothing but caring providers. If someone rushed me, I would have stopped them. I would recommend to people who are able to manage virtual care and have an overall care plan.”

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.
