Excellent experience! Dr. Hatzistefanou is extremely knowledgeable and explanatory – the extraction was done quickly and painlessly, with immediate implant placement, with no post-operative pain or swelling. Dr. Mitsaki provides high-level dental care, a true calm force who helped me manage my anxiety with her attitude and patience. Ms. Ferenia, the secretary, is always willing and helpful, with immediate response and a sincere desire to facilitate. The entire team is distinguished by its kindness and professionalism, while the space is spotlessly clean and equipped with modern means. Congratulations to everyone! I highly recommend it.
