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.

I needed assistance from my wife for hearing and answering questions because my hearing is poor and I have memory loss. She was not aloud to come in with me so the appt was a complete failure as I could not hear what the Dr said and was not able to answer most of his questions because of my memory problems. Since then we have been contacted by phone and have agreed to return to Dr. Sadler's office for the next scheduled appointment in November. if at that time things are handled as they previously wereat the first appointment we will haveno alternative but to research another cardiologist. At this time we are hoping the next appointment will be successful and things will be handled differently in regards to my medical difficulties.

Reviewed on Jun 12, 2020

at the end of the appointment I left completely frustrated that I was unable to hear and understand the Dr and the staff. I am 75 years old with a history of CHF and valvular disease and I am hoping that on my return for the next appointment I am ableto have my wife accompany me so she can help with the questions and history they ask for during appointments. If at that time she is not aloud we will not be able to keep the appointment.
