"I can not begin to express how having Dr. Marcantel as our doctor shaped our entire prenatal care and delivery experience for both children. He has a magical way about his care - patient, soothing, empathetic, humorous, focused, and professional. He had this way of making me feel like I was his only patient. His responses to my questions were thoughtful and his use of analogies and storytelling made the abundance of information all so easy to understand! I received excellent care from the other 3 doctors in the office as well; each had his/her own unique way of taking great care of me, even after my delivery with my second child. As I reflect on that glorious time, I will always smile fondly on the amazing experience I had with your team in the office and in the hospital!"
