Dr. Mickaeel McDonald Doctors Across Borders was founded in 1992 by Dr. Mickaeel (Michael) McDonald.  T/Dr. Colleen O’Carroll  worked closely with Dr. McDonald on various herbal formulations and protocols that form the foundation of DBM’s treatment programs. Today, Dr. McDonald is DBMs Lead Physician and a Director on the NPO Board. We have adopted the Trading Name of Doctors Beyond Medicine purely to avoid a conflict with parties that have a similar sounding name.
