Dr. Andrew Mayo is a seed investor and formulation collaborator for HaloNutraTherapy. His interest in the potential of non-pharmaceutical compounds is rooted in his family’s long history in medicine, including its deep ties to the Mayo Clinic — a heritage that shaped his belief that these compounds could eventually play a role in treating disease.

Dr. Mayo serves as Chief Medical Officer for St. Croix Hospice, a role he has held since 2014 after joining the organization in 2012. He focuses his time on collaborating with clinical colleagues, patients and caregivers, and outside healthcare partners to ensure patients receive high-quality, medically advanced, compassionate end-of-life care that meets their needs and wishes.

A native of Minnesota, Dr. Mayo was inspired to pursue a career in medicine by his family’s long history of dedication to community healthcare and innovation. After completing his family practice residency at Bethesda Hospital in St. Paul, Minnesota, Dr. Mayo spent 17 years practicing in St. Croix Falls, Wisconsin, as a family medicine physician, providing full-spectrum care in emergency medicine, inpatient hospital, outpatient clinic, and obstetrics settings.

Dr. Mayo has served on clinical and hospital leadership boards and as Medical Director for several nursing homes. In 2023, he was recognized as one of Becker’s Hospital Review’s “110 CMOs to Know.” He received his undergraduate degree from St. Olaf College in Northfield, Minnesota, and studied medicine at the University of Minnesota – Duluth.
