Didn't enjoy my experience with Dr. Oyola. He was a bit disorganized when speaking to me. It was challenging to understand him. When it came time to discuss my treatment plan, he second guessed himself multiple times.

This office seems to have a problem seeing patients on time. My appointment was at 10:00 and by the time I was finally seen it was 11:30. This is not the first time it is consistently late seeing patients.

The self check in kiosks are a terrible idea. This is an oncology center where people come to heal, not do the job someone else should be there to do. Many times over the four plus years as a cancer patient I have watched older or very ill patients struggle signing in. This shows zero compassion on Wellstar and begins the visit for many in a frustrating manner. Overall, there are Angels working at the Oncology center. It's a special place. But my biggest complaint is the experience when you start the day. Get rid of self check in and replace with a warm welcoming smiling face.
