Medellin Guru was Jeff’s blog, covering topics like tourism, health, culture, visas, and real estate, aimed at helping foreigners in Colombia. The blog launched on July 20, 2017, and quickly became a leading information source for expats in Medellín and made many monthly events gathered over 200 attendees, promoting cultural exchange and connecting expats with local services.

Jeff’s legacy continues, as Medellin Guru continues to be active in providing valuable information relevant to foreigners in Colombia or interested in living in the country.
