Our Team

Peter Sacco, Founder and CEO

Peter wears a mustache because he is serious, but doesn’t take himself too seriously. He loves all things human, ocean, and travel. Peter’s vision is to scale Adelante’s handmade production and revolutionary impact throughout Latin America. His favorite bit of inspiration? “Life begins at the end of your comfort zone.”


Michael Pelzer, Co-Founder and COO

Mike's flaming red hair is an apt metaphor for his fierce passion in everything he does. He cut his teeth in non-profit management, priding himself in his ability to fix what's broken and lay the groundwork for long-term success. Mike operates under the assumption that there is always room for improvement and is fluent in three languages: English, Spanish, and Excel.


Horacio Alvarez, Co-Founder and Production Manager

Born the son of coffee pickers or “campesinos” in Pastores, Horacio Alvarez began working in his uncle’s boot shop at eight-years-old.
