Executive Board

Meet the Teen Health 101 Executive Board, a group of leaders that guide their respective departments towards meeting Teen Health 101's three values, reliability, inspiration, and education. 

Valeri Guevarra 


Valeri Guevarra is a 17-year-old junior at Indian Hills High School in NJ. Like other members of Gen-Z, she loves social media and the internet. Growing up with both, she witnessed the influence one voice or a collection of voices could have online, whether it has a positive and negative impact. Inspired by current events and her personal journey through health/fitness, Valeri founded Teen Health 101 to help teens lost in the masses of online health resources available, combat the spread of misinformation online, and amplify youth voices in healthcare.


Although she had an inherent interest in the healthcare industry with many family members pursuing nursing, she has cultivated her own independent passion for the field through Teen Health 101. Some of her favorite topics to cover are medical careers, reproductive rights, access to healthcare, mental health, and nutrition. Guevarra is also a writer, athlete, activist, and public speaker. 


Valeri hopes that teens utilize TH101’s resources to remain educated and informed about the health world around them. She also hopes that the organization inspires others to take initiative and create a solution to problems they see in the world and not be afraid to be a voice even in an adult-dominated field like healthcare.

He enjoys sports in my free time, and I’m a member of my high school's football and track team! He hopes that as time goes on Teen Health 101 grows in prominence into being the centerpiece around teen health!

Eve is passionate about advocating for global healthcare, promoting climate justice, fostering loving and accepting environments for all, and engaging peers in forward-moving political discussions. They can be found cooking, writing, walking, or listening to music in their free time. Eve hopes to see Teen Health 101 empower young people with knowing the strength of their voice and the power of their bodies - and how to protect that resilience with healthy routines.

She is also interested in neuroscience, psychology, and biology, and loves advocating for mental health awareness. Additionally, she loves to read fiction and go on walks during a nice day and participates in dance, plays the piano, plays the ukulele, as well as sings.
