  • "I cannot say enough good things about Dr. Triantafillos. He is truly an exceptional hematologist. From my very first visit, he has shown not only deep expertise but also a level of compassion and attentiveness that is rare to find. He takes the time to explain everything clearly and makes sure I always feel heard and cared for. His team is just as outstanding. Karen, his nurse, is incredibly kind and supportive, always following up and making sure everything runs smoothly. Fedeleine, the phlebotomist, is gentle, precise, and has a calming presence that makes blood draws stress free. And Nadyra at the front desk is warm, welcoming, and keeps everything so well organized. Together, they make every visit a positive experience. I am so grateful to have Dr. Triantafillos and his team in my corner. Highly recommend."
