Mindful Health Solutions is one of the nation’s leading providers of innovative behavioral health care with a focus on emerging psychedelic research, precision medicine, and cutting-edge treatment protocols such as TMS, Esketamine, and IV Ketamine for patients struggling with treatment-resistant depression and other psychiatric illnesses. We founded one of the first TMS-focused clinics in the US and have deep expertise in the field of non-invasive brain stimulation. We then went on to establish one of the first clinics to provide Esketamine (Spravato) therapy at scale, and recently incorporated IV Ketamine into our depression treatment pathway. Patients at Mindful Health Solutions have access to true thought leaders in the field focused on bringing academic rigor and years of experience with novel therapeutics to an integrated treatment strategy. We are currently leaning into the promise of psychedelic therapies for depression and PTSD as well as leveraging our extensive clinical outcomes repository to develop predictive algorithms that will help guide our clinicians in selecting the best treatment modality for their patients. We have grown to 22 outpatient clinics located in California, Texas, and Washington and continue to expand our innovative, precision-medicine platform into new markets.
