Dr. Kalaharios and team were prepared and thorough w my tele health appt. very impressed

April 10, 2020 12:00 AM

Dr. Karahalios explain my back surgery clearly. I asked about my back healing on its own and he said it could so we can wait on the surgery. He answered all my questions and we talked about exercises to stay away from. He listened carefully and I appreciated that. He said he can refer me to a different specialist if I want to. Also, I can call him if I have more questions. Thank-you!!

April 1, 2020 4:14 PM

January 27, 2020 6:29 PM

I interviewed 3 if the top surgeons when I was confronted with spine surgery. Best thing I ever did was go to Dr. K a nrurosurgeon..he's the best!!!

January 27, 2020 6:29 PM

Great Dr. Listened, offered suggestions, attentive and didn't input on computer during visit. A turnoff for patients when that occurs.

May 19, 2019 7:00 PM

Dr. Kakrahalois relies on his nurse to communicate with patients, even at visits

April 17, 2019 7:00 PM

Positive - Short visit but good news.

March 28, 2019 7:00 PM

I am very fortunate to have Dr. Karahalios as my neuro surgeon!!! He has performed three operations on me in the past two years. He is kind and always willing to listen.

March 1, 2019 6:00 PM

Doctor Karahalios .. BEST SURGEON ever.. Great bed side manner ..all around great person!

February 24, 2019 6:00 PM

My office visit was wonderful! Before arrival & after. I couldn't ask for anything better - from information desk in the front lobby to the techs giving MRI & CAT scans & from the doctors office staff to the doctors nurse on the follow up - she called when she said she would - even before she said she would & answered ALL my questions. I know everyone is very, very busy but all along everyone took their time & treated me as I was their only patient I really have no complaints whatever - just a thank you for everyone who helped me.

February 6, 2019 6:00 PM

Very good & friendly.

Excellent experience.

January 18, 2019 6:00 PM

first visit was very quick, only about 10 minutes. Have not seen him since, only talk to his office. Surgery scheduled for Feb. 4th.

January 18, 2019 6:00 PM

Dr K is the most qualified back doctor I know. I have recommended at least 20 people to him. he is so professional.

January 13, 2019 6:00 PM

Awesome staff! Very professional, compassionate, and caring. l have been dealing with the issue for a long time and it took Dr. K no time at all to find the problem and fix it. I would gladly recommend him and his staff to anyone that would need the services provided.

November 5, 2018 6:00 PM

Dr Karahalios , BEST DOCTOR and SURGEON EVER!!

September 23, 2018 7:00 PM

dr Karahalios is fantastic! awesome bedside manners, kind, and his nurse X is terrific. I would recommend anyone w back problems toDr Karahalios.! his receptionists X and X are wonderful - they are nice, quick to pass on messages to the nurses and always return calls promptly.

August 5, 2018 7:00 PM

Dr. Karahalios is attentive and empathetic. I had a surgery that did not stay fixed a few moths ago. He listened when I said I had continued pain and allowed me to have another MRI. Now, after my second surgery - I'm feeling so much better.

June 14, 2018 7:00 PM

Good experience. Seeking a second opinion regarding a medical condition.

April 8, 2018 7:00 PM

Dr K was very kind and reassuring and my surgery couldn't have gone better. I'm grateful he agreed to do it.
