"I am so thankful for Dr. Bakkar and their staff. They have been so kind and professional. They take the time to explain what is going on and are very reassuring. His assistant Linda is always so kind. They actually return phone calls. Which is something not always encountered in the medical field. Dr. Bakkar is compassionate but honest with his assessments and willing to take the time to get the facts right. I am so thankful that as I am experiencing the scary symptoms I am having that I have a neurologist that is willing to go over everything."
