2022-2023 SMADIE Intern

Louis Tan

Louis Tan is a first generation, premed student who grew up in the Bay Area. He was diagnosed with inflammatory bowel disease as a child, which has helped shape his desire to pursue medicine as a career. He is passionate about educating underserved populations, and learning about how new technologies have the potential to revolutionize science and medicine. As a hobby, he likes to tinker with different aspects of art and design.

Louis attended the February 2020 SUMMA Conference at Stanford University, where he met Dr. Poullos. Inspired by Dr. Poullos’ story, he reached out to see how he could contribute to SMADIE. Currently, Louis manages and provides creative input for SMADIE’s social media channels.

Richie Sapp

Hey everyone! I am a 4/5 medical student currently on clerkships! One of my big passions in life is disability advocacy. I have worked on disability issues on the main Stanford campus and here at the school of medicine. I was one of the founding members of MSDCI (Medical Students with Disabilities and Chronic Illnesses). I joined SMAC because I wanted to improve Stanford School of Medicine's approach towards disability, from being reactive to proactive, and become a leader that other medical schools will follow in creating an environment that includes, accommodates, and promotes disability as diversity.
