Outside of medicine, Dr. Reyes-Villa has a deep love for cinema and the fine arts. He enjoys playing multiple musical instruments, composing songs, and sharing his creative interests with his three children. During your visit, you may hear a movie quote or share a laugh—he believes humor and positivity are essential parts of connection and communication.

Dr. Reyes-Villa also founded the Norma Villa Foundation in honor of his mother’s legacy, supporting and encouraging folkloric artistic expression in Colombia.
