Mrs. Koster is amazing. At one point I was already leaving Dr. Yagzi‘s practice being that they were many rude staff members and physicians. Mrs. Koster is very thorough and made my decision to stay with Dr Yagzi‘s practice. She’s very caring and compassionate about my health and needs.. Thank you!
