What is your role at 4th Source?

I am a recruiter and HR Assistant in Mexico City. I help with administrative and HR functions including inductions, events, HR reports, coordinating flights, and many other office tasks.


What do you love most about working with 4th Source? 

I love that I work with a highly specialized team, who has a deep knowledge of HR methodology, technology, and processes.  It is an amazing environment because we learn a lot from each other and have the possibility to share information.


What is your most memorable moment at 4th Source? 

My most memorable moment at 4th Source was when our largest customer certified the Mexico City office. It was an amazing achievement because and all the teams in HR and Service Delivery worked together as the office doubled in size within a few months.


When you're not working at 4th Source, what can we find you doing?

My hobbies revolve around my family. I am active with my three-year-old son. I consider myself a “dad gamer” and love playing video games. I also listen to metal rock, enjoy traveling, football, and watching the NFL.




What were you doing before you joined 4th Source?

Before 4th source, I was working at an IT infrastructure and Telco company as an HR coordinator. I was responsible for recruitment, policies and hiring for the company. I’ve lived in Mexico City my whole life, but I love to travel and learn about different cultures, food, and music form the U.S. and other countries.


Where do you see your future?

One of my goals is to start to earn a Master’s degree. I would also like to continue learning French. I see myself in the future managing more HR responsibilities at 4th Source and establishing a mid-time business near my home.
