Providence Patient
I wish every Doctor had Cardiologist Dr. Boris Laretta's manner. While too many doctors relay technical information, Dr. Laretta makes sense of it relative to my life now, my future expectations.I leave an appointment with him wiser, informed, and empowered with all lifestyle and medical options understood. I leave an appointment with Dr. Boris feeling peaceful about my imperfect, fragile human life.Would that all Doctors, Religious leaders, and those in positions of wealth and power did the same.
