Carl Thomas always listens to me and is so very knowledgeable and always gives me peace of mind for whatever I'm going through and he always gets back to me right away and lets me text him about the same issue and doesn't make me keep coming back in and he answers quickly and readily on the same day, really on the same hour that I text him. And he did the medical assistants did bring up the following. Carl Thomas didn't need to go over that issue so that's why I put a one because he didn't discuss it but his he already knew that it had been taken care of so I would have given that a yes definitely also. I want him to have a perfect score because he deserves it. So thank you very much. He's a wonderful doctor.
