Dr. Khan Literally Saved My Life

"Dr. Khan literally saved my life by repairing my brain aneurism with a stent through an angiogram. And then when I went to her office for my follow up appointment two weeks later, not only were her office staff very pleasant, but Dr. Khan spent quite a bit of time with me answering every single one of my questions.

I cannot thank her enough for her level of care and expertise in performing my surgery. I highly recommend Dr. Khan to anyone who is facing neurological problems."

Dr. Shah-Naz Khan is the Best Neurosurgeon in all of Michigan!

"Dr. Shah-Naz Khan is the best neurosurgeon in all of Michigan!  It is amazing how truly concerned and attentive she is, considering how busy she must be."



Dr. Shah-Nah Khan is Fantastic!

"Dr. Shah-Nah Khan is fantastic.  She’s responsive, aggressive and treats everyone from the ER physician to patient’s family members with respect and compassion.  She took a patient of mine to IR for embolectomy recently, and the family wouldn’t stop talking about how wonderful she was and how they trusted her.

The next day, the ER RN who accompanied the patient during the procedure raved about how Dr. Khan took time to educate her during the procedure, how even keeled she was and on and on.  She is a great addition to the Hurley team."

I Believe Her Care is What Kept Me From Having Surgery!

"Dr Khan met me in the hospital after I sustained a nasty fall resulting in a back injury. She was kind and understanding and took time to explain my injury and how we were going to treat it.

I believe her care is what kept me from having surgery. The follow up has been wonderful. The kindness of Ms. Bhavna was so wonderful. She was willing to hep with any issue I had. Thank you so much Dr. Khan and Ms. Bhavna!!"
