In addition to his work as a concierge mental health and addiction interventionist, Marc provides ongoing strategic consulting to the J. Flowers Health Institute in Houston and works alongside the organization’s founder, Dr. James Flowers, to help further the Institute’s mission to promote whole-body wellness for complex clients with mental health and medical diagnoses.
