Jen Brewer, MA, RD

Jen Brewer, MA, RDN has a home in Minnesota, but her heart lives Guatemala. She works with several NGO's in various parts of the country, helping to implement programs that utilize family gardens to help sustainable nourish families and fight the cycle caused by malnutrition and poverty. Having lived in Guatemala twenty years ago, Jen got a first hand look at the lifelong physical and mental devastation caused by lack of adequate nutrition, especially during the early years of life, and always wanted to return once she completed her education and could really help make a difference. She did return in 2014, while pregnant with her seventh child, and turned her passion into a family affair, taking her husband and children with her to various projects throughout the country.

Jen is over the moon to be a part of the GMIG and is excited to rub shoulders with other like minded people in this group! When not traveling you will find her taxi driving her kids all over town, cheering like crazy at their events, and basically trying to survive life as mom.
