had this to say:
My experience was a completely satisfying professional encounter. The reception, appointment scheduling and billing are courteous and accommodating. The dental technologist, Mary, was thorough in her preoperative and post surgical instructions. She was both knowledgeable and comforting. Dr. Liaros is an outstanding professional in his field. He exudes confidence and concern for his patient's comfort. His conversation during surgery with Mary and my wife was light-hearted and alleviated any stress.
I would, without reservation, recommend Peter Liaros, DDS and Periodontal Implant Specialists, Ltd. to anyone in need of such services.
