I asked him basic questions and was told to schedule an appointment with his brother who is an endocrinologist. Our initial appointment with him to diagnosis my mother's cognitive decline was about 6 minutes top. So uncaring and unprofessional. Called office 4 times asking for a return call to get a referral to new specialist and have not received a call back. Unacceptable. It is impossible to get a live person - now they have AI Amy answering the phone to direct you down the rabbit hole. Avoid unless you like being treated like a widget on an assembly line.

Endocrinology is clearly not their strong point. This particular practice went above and beyond to be misleading and unhelpful. Perhaps the diabetes care is good, but I would avoid this practice for anything but. Truly disappointed by how poorly my experiences have been.

My condition is under better control than ever, and I feel as though the staff is very knowledgable. The ladies at the front desk are friendly, and also really know what they are doing. I also like that they have people available via appointment to help you with pump training or continuous glucose monitor training. This office is very busy, the treatment you get is great, but they are so busy it is difficult to change appointments. I would definitely recommend Fox Valley Endocrinology to diabetics looking for treatment.
