I saw a cousin's wife in the lobby and I knew I was in a good place. The nurse was very kind. She kept apologizing for "my cold hands." Dr. Hernandez knew my medical history,(my chart), and explained my 3 problems and how we would explore deeper to find what is causing by failing health? After the Dr. exam I visited my aunt and cousin, and they are patients of Dr. Hernandez, and they told me he was great he was, and that he not only cared about their physical health, they said he cared about their spiritual health also! I am so blessed to get such a good doctor by chance.
