I am a cancer patient who went through chemo.I have been feeling a little out of breath or more like a gasp of air. One of the side affects of the Chemo said It may cause a heart condition so I wanted to make sure. I had an appointment with Dr Saddler who I felt was more worried that I still hadn't gotten the vaccine than me having a heart condition. Even though I let him know that I was still recovering from surgery and had discuss with my oncologist he felt the need to scold me. I will not be following g up with him.Thank you

Happy to have Dr Saddler taking care of me

Reviewed on May 12, 2021

Dr. Saddler was extremely knowledgeable about my previous history. You can tell he reviewed my case prior to my visit. The visit went pretty fast. Dr. Saddler did show that he cared. Maybe in the future more conversation to make the patient feel more comfortable. Not sure if he had another patient to get to but other Dr's at the CCF have spent a bit more time with me. I know all Dr.'s are different. It was a while since I had seen him so I was a bit nervous. Dr. Saddler shows up as extremely knowledgeable and made me feel like he addressed my concerns.
