Dr Fernicola was very pleasant and professional. He introduced himself advised he had reviewed my mother's chart and asked us what brought us in today. He listened to my mom, reassured her they would explore further to determine her condition and provide appropriate care as needed. He ordered a cardiac echo which he explained beautifully to my mom. He reassured us that this test would provide us with the answers we needed. He provided options of next steps if the test was positive or negative which was comforting to my mom.
