He is a terrible communicator. I needed a correction surgery and he was very flip about the time frame. Told me it could be up to 6 months to get me in. I felt like I was another person on a assembly line. Dr. Warren only called me after my primary contacted him. Also miraculously I was able to get a correction surgery the next month. Thanks to my primary Doctor.
