Horrible customer service. Phoned the office several times and never received a return call. First…read moreappointment was rushed and Dr. Kassar seemed completely uninterested in my elderly mother. 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.

A few weeks ago I had gone in there knowing i made an appointment to get my flu shot. I called on 10/27/14 recorded I called on my phone that I called the office to make an appointment only to get a flu shot. I show up 11/07/14 on time and the front desk lady tells me she doesn't have my down on the schedule I was so upset. However, the nurse who takes my blood for me saw me in the waiting room asked why I was there. I told her she said nobody told her i was waiting for just the flu shot. She apologized and gave me the flu shot pretty fast. I felt happier but still it made my husband want to change Doctors because of it. The whole family was with me that day. We waited entire 30 minutes for me to get a flu shot, crazy day.

I LOVE DR ROBERT!!!…read more I have been seeing the team here for 6 years. I have been Type 1 Diabetic since I was 9. Once I moved to Chicago, I was so glad to find the team here. Dr Robert is so great. So many doctors I have seen in the past treat the disease, chastise the patient, and get little result. Dr Robert treats the whole person. AMAZING. The lab is in his office. Everything is done right away. He personally writes follow-up notes a week or two after your visit. WHO DOES THIS ANYMORE??? Amazing. His Diabetes Educator/Nutritionist/GURU Monica is the best. I love her and would follow her anywhere. She is direct, honest, and insighful. I give it a 4 because the front desk people can be rough. THe lady who worked here for a long time retired and the new people just aren't her. If you are diabetic, see these people.

I was diagnosed with ulcerative proctitis and thyroiditis in August 2017. I was under the care of a…read moregastroenterologist and an endocrinologist, both of whom are experts in their field but each only concerned with the symptoms related to their disciplines. I knew I needed to find a medical professional to help me understand and manage my conditions (both of which were causing me some serious problems) and to address the root cause of the disorders, as I believed them to be related. I began seeing Dr. Trish Pearce in September 2017 and I continue to see her on a monthly basis. Dr. Pearce's expertise in the treatment of autoimmune digestive and thyroid disorders has been invaluable to me. I have followed all of her recommendations, including dietary changes and the use of high quality supplements. As a result, my thyroid levels have been within normal range since February 2018 and are being managed solely by myself and Dr. Pearce, without the use of pharmaceuticals. The ulcerative proctitis is under control as well due to Dr. Pearce's treatment plan and a medication prescribed by the gastroenterologist, who I see every six months for medication management. I fully expect, under Dr. Pearce's care and guidance, to reach a point where I no longer need the medication. I consider Dr. Pearce to be my Primary Care Physician as she employs a holistic approach to my healthcare. I have total trust in her as a medical practitioner. Please do yourself and your health a favor and contact Advaita Natural Wellness. Be patient and give yourself the time needed to heal under the care of Dr. Pearce or Dr. Alsop.

I can't remember the last time I felt so completely heard and understood. And she even shared a private story from her life that let me know she truly understood what I was telling her about. Not only is she a great listener, she does a fabulous job explaining why I was having ear aches and how this can be addressed. Thank you Dr. Kim!! The only downside is that I had to wait almost 2 months from the time I called to get an appointment to actually seeing her. Tells me she is very popular but makes me wonder what I'd do if I had a more immediate issue.

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.
