Matri was born in Guatemala City and emigrated to the U.S. with her parents when she was a toddler. Her childhood years were spent in Washington D.C. She was fortunate to have been aided and encouraged to apply to a great school in Virginia by a teacher who saw a spark in her when she taught her in the DC public school system. Maitri was disadvantaged in that she then became the only Latina in her class for many years. When it came time to go to college, she left for New York City, the place of her childhood dreams, to attend Barnard College, Columbia University. She graduated with a degree in Foreign Area Studies, with a concentration in Latin America. When she finally realized what she wanted to do professionally, she enrolled in three extra years of undergraduate coursework in order to fulfill the requirements for application to veterinary medical school. She graduated from the Virginia-Maryland Regional College of Veterinary Medicine with a degree of Doctor of Veterinary Medicine.

In addition to her professional life, a life she finds not only rewarding but constantly challenging, Maitri is a wife and a mother of three young children. She is an activist, interested in furthering knowledge, participating and directly involving herself in the areas of human and non human animal rights and environmentalism. She tries to engage in the world around her to influence it as much as she can to help secure a healthy, peaceful living environment for her children and all other living beings on the planet. She is a benevolent misanthrope, a polyglot, a lover of travel. She has wild plans of obtaining a law degree when her children are older. She is currently practicing emergency medicine and volunteers her services wherever they are needed.
