"Dr. Ruiz is the best Endocrinologist in Fargo. He is very attentive and professional. My A1c has never been better and I have had diabetes for more than 20 years."

Vitals (Dr. Raul Ruiz Esponda)

"She answered questions thoroughly and did not make me feel like I was taking her time. I feel supported by her and I would recommend her to other diabetics."

Healthgrades (Terryl Johnson, APRN)

"I felt like he talked down to me and made my visit feel horrible... I also think he did a test that was unneeded in his examination that feel like a violation."
