Dr. Liaros and his entire team are great. I have had several procedures with them and each time Dr. Liaros has called me the next day to ensure I was doing well. He takes the time to explain the prodcedure so I understood what was happening and even got to see before and after photos. The entire team is nice, caring and professional. Highly recommend Dr. Liaros.
