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.

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

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

Our original appt was for 7 weeks away - the soonest they could get us in - but Barb the Drs asst called us a few days after we scheduled & got us in the next day - AWESOME. A 7 wk wait was terrible.

Have been a patient at Dreyer for over 50 years. Had a compressed _____ fracture in Florida. Needed a neurosurgeon when we came home. Dr. K. comes to Dreyer once a month. Am not use to having a dr. say he WILL call me - and then not follow through. It took several calls to get answer to return my calls.

I have mainly dealt with Dr. Karahalios, Megan, Barb, and Shelly and hold them all in the highest regard.
