Peng at the Lafayette lab is absolutely amazing. She runs the entire location herself checking patients in, performing blood draws, handling insurance, and managing the workflow seamlessly. She is incredibly professional and efficient. As a fellow medical professional who often comes in for specimen drop-offs, I truly appreciate how smooth and pleasant she makes every visit. Very grateful for her dedication and hard work
