Patient | September 11, 2017

I feel as if my provider rushes through our visits at times.
Patient | July 28, 2017

She told me to continue like I was with my avg. B/G above 300. No concern!
Patient | July 27, 2017

Dr. Carranza-Leon is the absolute best and I recommend her to anyone that has a need for an endocrinologist. She always makes me feel like I am her only patient that day and I am always confident that she remembers my medical history. She shows an amazing attention to detail and remembers conversations that we had at my previous appointment - a year ago. She is simply amazing.
