Dr Susan Thomas was great in every way as was her Nurse Assistant
May 13, 2025
Always runs late. I was the first appointment of the day and she was 30 minutes late! And the nurse said something along the lines of "oh she's usually late" so this is a frequent occurrence. I wish I could charge doctors late fees like they would of me if I was running late. Guess what, we also have jobs and other things going on in our lives, so please respect our time as well!
