"I would like to give a special recognition to Maria Castillo. She is an amazing women and I am truly blessed to have found her for all of my medical needs. She has been the first person I can trust in the medical field. When you are being seen by her you have her complete attention (unlike most medical examiners) and she genuinely cares about her patient's well-being. I have struggled with in the past to find the proper help for my physical and mental health and she has given me all the tools to safety I need to live a healthier and happier life. Thank you Maria!"
