My family and friends – without a doubt!

Mexico City as it is so vibrant and culturally diverse. The food is incredible and the constantly changing art galleries, museums and music venues would keep anyone busy for months.

Social impact creates opportunities and makes a huge difference in the lives of others by addressing systemic challenges in a sustainable way. It moves us away from a simple “do no harm” approach to business by requiring intentionality to address social and environmental objectives whilst generating financial returns for investors.
