I just found out today that Dr. Casillas is no longer with us anymore. I am so sadden by this news, as he has saved countless lives with his work, including my own! He has touched so many people in ways that I never imagined a person could. The clinic seems so desolate and empty with him gone and I'm not sure that anything will ever "feel" the same again! He was truly an amazing man and will be/is dearly missed greatly! I send my love and prayers out to his family as I know they are hurting the most right now. Rest in Peace Dr. C.... God has gained another angel!

Throughout his entire life, my father was ready to take on the world and driven to succeed in a way that will always amaze and inspire me. I will always cherish the times when I was younger when he made time to help me with my school science fair project or building a pinewood derby car for Cub Scouts while working his 80 hour work weeks at multiple hospitals. He always was around when I needed them the most. Thanks Dad ❤️

I remember my dad taking my sisters and I to visit with my Uncle Mike and the family. Uncle Mike had a way about his laugh that always made me smile.
