Hi, I’m Patrick. I’m a freelance science writer based in the San Francisco Bay Area. I hold a bachelor’s degree in Athletic Training and a master’s in clinical exercise physiology. I used to work in the clinical setting as a certified athletic trainer, physical therapy aide, and a certified strength and conditioning specialist. After working in the clinical setting, I went back to school and became a teacher. The goal of my content is to help normal people, not just pre-med students, learn about the human body. That might mean explaining a topic from an anatomy class or exploring a topic from medical history.
