Awesome Dr and awesome staff
- 5 out of 5 starsReviewed on 12/26/2025
It takes months to get an appointment because Dr. Kalfas is well respected so I understand why it is difficult to get an appointment when one would like to see him, which is the only reason I rated that area Fair, instead of Very Good.

He was completely relaxed, took his time to explain everything in detail. Most Doctors are rushing from one patient to the next. Dr Kalfas gave us his full attention. Answered every question. I know I am in the best hands for my upcoming surgery.

Dr Kalfas immediately put us at ease when he came into the room. He did an excellent job of explaining my neck issues, and his plan for addressing them. He also gave us a detailed account of the potential risks versus rewards.
