Dr. Ruddy was very helpful and informative during our follow up phone call. He answered all of my questions and was very reassuring in regards to my results. Ask him anything and you’ll get a very informative answer. I recommend Dr. Ruddy 100%

I met with Dr.Ruddy via a video appointment as a follow up for a test I had. I had not met him in person before this session, but he made me feel comfortable throughout the session. He was very helpful and informative, making sure that I understood everything he was explaining to me. I felt that he gave me all the information I needed, and I was very satisfied with the session.

The videoconferencing "telemedicine" visit was smooth and relatively easy, especially with CCSD's ability to read my CPAP card remotely.
