Abbie Seto


Abbie Seto is currently a high school senior from Calgary, Alberta Canada. She has been doing MUN for about 2 years, including many local physical conferences, a national conference and a plethora of international virtual conferences. She loves MUN not only for the fact that she loves public speaking, she also loves discussing different social political issues, especially human rights issues. MUN provides her with a platform to do what she loves, meeting new people, voicing opinions and making the world a better place. Once you get to know her, she would be one of the most talkative and energetic people you will ever meet. She’s a social butterfly and she loves meeting new friends and people. She’s a perfectionist workaholic too, but if she’s not working on projects (which is rarely), she would be seen actively volunteering in her community, or doing aerial silks, or swimming or doing art. She believes that in this day and age, when possible, it’s important to advocate and stand for human rights. She looks forward to hearing everyone’s ideas and meeting new people.
