Testimonials
“Can't say enough great things about my visit today with Dr. Nathan. He was extremely thorough and took time to walk me through everything he was doing in order to gain a full understand my issues. Not only did he make me feel completely comfortable but I felt he genuinely cared about the issues I am having and my health. On top of that he is so kind and easy to speak to. Highly recommend!!”

“As always, he was informative and insightful. He asked revealing questions. Dr. Nathan is the best physician I've ever dealt with.”

“Dr. Nathan = Fabulous. Everything about my experience was informative, thoughtful, personalized, and candid. He took the time to listen and explain. He was fully present and kind. Moreover, due to severe weather in Chicago, the office staff was out, and Dr. Nathan just took care of things... No Fuss. Simply outstanding.”

"If you want a doctor that is going to advocate for you or your loved one, it's Dr. Osher. He is the best of the best! My mom fell and hurt her leg and Dr. O stepped in and made sure she is getting the best of care. Feeling the most confident I have along this journey since Dr. O has been in the picture. This type of care is priceless!"

"Dr. Osher is a great listener that enabled my elderly father to accurately describe the physical issues that needed to be addressed and solved. Dr. Osher was kind, considerate and very matter of fact in describing the best treatment of exercise, food, sleep and meds. The treatment was prescribed and Dr. Osher followed up to ensure my Dad was over his medical difficulty. Excellent doctor and a fantastic staff who care 24/7."

"I wouldn't be here today if it weren't for Dr. Nathan and your practice. I'm Dr. Nathan's and NSMA's biggest fan. I thank you both so much.
And yes, everyone of the girls I speak with over the phone is super pleasant."
