My oral surgery experience with Dr. Liaros was very positive. During my consultation Dr Liaros and his staff were very clear about my surgical plan and what I should expect during the procedure. My oral surgery went very smoothly. Dr. Liaros and his staff were very thorough, explaining steps during the procedure and providing details on post surgery care. I was pleasantly surprised at how quickly and effectively my procedure was completed.
