Brand Newland Leadership

Brand Newland, PharmD, MBA

With over 15 years of leadership experience in creating new healthcare solutions, Brand has worked to bring high quality approaches to payers, employers, healthcare providers and patients. In 2003, Brand joined OutcomesMTM, an innovative pharmacy Medication Therapy Management company. The fourth employee, Brand oversaw business development and operations, seeing the company through rapid growth and its acquisition by Cardinal Health in 2015. Brand received a Doctor of Pharmacy degree from the University of Iowa and holds a certification in pain management. He has also completed an MBA at the University of Chicago Booth School of Business. 

He lives in Austin with his wife, and dedicates his free time to traveling to watch sports events and maintaining his ace pickleball skills.
