The phlebotomist was gentle and efficient, putting me at ease during my blood draw. The medical assistant was attentive and thorough, ensuring all my questions were answered. Dr. Chu himself was knowledgeable, caring, and took the time to listen to my concerns. The professionalism and kindness of the entire team made my visit truly exceptional. Highly recommend! ⭐⭐⭐⭐⭐"
