Professional, polite, listened, and welcoming. As it was our first meeting, before making any conclusions on my condition, Dr. Tsakonas is sending me for blood work, and requesting tests on my heart. He is asking Insurance to approve a timely followup appointment. My entire experience with the office staff put me at ease. 😃
