Check in was messy. I understand that the transition to EPIC can have hiccups but I was asked to fill out the same three forms online ahead of time for 4 separate appointments (2 "nurse visits", Dr LaPlant and my ultrasound. And for some reason they asked it all again at check in. I've also been asked to complete the same forms again for an appointment tomorrow. Very annoying.

Dr LaPlant is an EXCELLENT DOCTOR. He listens to my concerns and helps me if I have any issues. He is smart, caring and kind. I am so happy he is my doctor. He explains everything in words I can understand. I would recommend him to my family and friends. He really is the GREATEST. [patient name removed]

Both my daughter and I were impressed by Roberta and by Dr. LaPlant. They were very friendly and extremely knowledgeable and gave us great and detailed information. I wish the people at the front desk were friendlier and that the facility's waiting rooms weren't so mobbed and had warmer decor.

I was confused as to whether radiation was appropriate or not. I think things will be clearer once I meet with the oncologist. Dr. La Plant was excellent, I know that the team needs to meet first.
