Upon graduating from the College of Veterinary Medicine at the National University in Colombia.

After his KSU experience, he joined the faculty at Ross University School of Veterinary Medicine where he worked as clinical professor and Associate Dean for clinical affairs and professional opportunities mentoring and monitoring the progress of the clinical year veterinary students in the 33 clinical affiliates around the world. In 2017 he accepted the position of clinical professor and Associate Dean for academic and student affairs at the University of Florida College of Veterinary Medicine.
