Our Team

Shannon Malish

Chief Executive Officer + Founder

Shannon is a Licensed Clinical Social Worker who received her master's degree from the University of Texas at San Antonio with an emphasis in addiction counseling and received her undergraduate degree in Business Management from Azusa Pacific University. She has a vast experience in leading and directing mental health and substance use disorder treatment facilities. As the wife of a police officer and military veteran, Shannon takes a special interest in trauma resolution and brain health.

After years of teaching and delivering treatment for depression, anxiety, PTSD, substance use disorders and various other mental health disorders, Shannon sought out a team of psychiatrists and neurologists to investigate the missing component of how medications are often not the solution to these issues. What she has found working with this team of experts is that many people suffer from an imbalance in the brain. She was trained and certified by Neurocademy, an international group of the most advanced group on rTMS (repetitive transcranial magnetic stimulation), and is also certified in TMS.

This training along with the data on individualized approach is what led to her revelation to assemble another team of highly experienced doctors and scientists to develop a new and non-invasive way to treat this brain imbalance, thus delivering the revolutionary treatment iTMS ™.

Nancy Jordan

Community Outreach

Normally a background in debt resolution, banking, educational sales and private golf and country clubs would not be what one would think of as the ideal qualifications for a community outreach spokesperson. Yet, building relationships, creating partnerships and promoting customer focused services is what this position is about.

Having experienced this therapeutic technique first hand gives Nancy a passion and personal appreciation for the benefits of iTMS. Nancy's goal is to advance awareness of and access to Brain Frequency Center for individuals, communities and clinical practice.
