Thank you to Dr. Ellis for prividing me a 2nd opinion on my wrist injury. Since I was not permitted to have family present due to COVID restrictions, I also appreciated that he was kind enough to communicate via facetime with my daughter. As always, he was thorough, pleasant, and professional during my appointment.
