Dr Longo is a very good endocrinologist. His Clinic always takes the time to walk me through things explain and show me how things should be done. I never feel like I'm in trouble as I have with past providers they always help me do better next time. I would highly recommend this endocrinology clinic to any diabetic I meet.

I met with Dr. Longo for the first time. He seemed extraordinarily intelligent, showed concern for how and what I thought and felt. He provided much new guidance and allowed me to choose the treatment plan with which I felt most comfortable. He left open the door to reevaluate with another doctor in three months. I have worked with him before and feel good about having treatment options for that appointment planed out depending on my progress.
