I am an East Coast transplant, born and raised in New Hampshire and now living in California for the past 11 years. I completed my B.A. in Behavioral Neuroscience from the University of San Diego before moving up north to the Bay Area. I graduated with a Master’s in Traditional East Asian Medicine from AIMC Berkeley in April, and became licensed shortly after in June. I have found passion and would like to continue learning about herbalism, reproductive health and pediatric care. 

 While not busy studying medicine, I enjoy gardening (I grow quite a few Chinese and Western medicinal herbs!), trail running, seeing live music and getting into an art project.
