Professional & excellent demeanor.

5 out of 5 stars

Dr. Pousatis gave a great explanation of upcoming surgery and fielded any questions I had. Her overview of different valve types and the pros and cons of each were particularly helpful.

Everyone was very personable. Listened to me and answered all my questions, did not rush me and used props to demonstrate which wS very helpful. Felt I was being treated as a person not just another number. Felt very comfortable and could feel confident being in there care.

She took good care of my brother and we are all just grateful for her from saving him from an unnecessary procedure that the other hospital wanted to do. Dr Pousatis is simply the best in the matters of the heart🥰👍🏽❤️.
