Dr. Codo was very attentive and friendly. She showed care and concern and gave sound advice. Her medical assistant Jiocelyn was also caring and friendly.

I first met Dr. Codo When I was looking for an endocrinologist to treat my mother back in the early 2000s. I was very impressed with her back then so when my current PCP wanted to transfer me to an endocrinologist for my thyroid she was the first person I thought of, and was very grateful to find her as part of Duly
