Dr. Grainger comes to the waiting room, calling the next patient's name, and takes them to his office. I view this as a personal courtesy, although I'm sure part of the reason is so that he can watch his patient walk. Dr. Grainger always answers all my questions and never seems to be In a rush -- he gives me as much time as I need. His office staff is friendly and efficient. All in all, an office visit with Dr. Grainer is an extremely good experience!

Dr. Grainger is a wonderful doctor. I appreciate all his help and how he has been able to find new ways to help me with my chronic migraines. I recommend him a lot to other people I know. It can be hard to get an appointment, so plan to be booked out a little bit, but he is worth the wait in my opinion.

This is the worst Doctors office I have ever visited. You are considered a new patient if you don't visit within 2 years? Most ridiculous thing I have ever heard.

Today I met woth this doctor. He said he cannot treat me because the tests he had me do show nothing wrong. He them stated the test only has 70% accuracy. He was a bully and I left in tears.....i should have guessed this would go bad after I heard him complaining in the eating room to the patient he saw before me about how he would rather be anywhere but at this office. He cost me hundreds of dollars and now I have to start all over woth a new doctor.

Dr. Grainger is an excellent neurologist. He has been my doctor since 2001. I find no difficulty getting appointments, the staff is very friendly, the office is OK and clean, and he is very knowlegable and current on medical issues. He may apprear a bit curt but he is not like that at all. He knows his stuff and give the patient plenty of information.
