Was there anything that you feel was outstanding?
Dr. Michael J. Fleissner is an exceptional cardiologist and has cared for me for many years. He was very informative about my cardio condition and recent hospitalization. He prescribed a change in my medications and explained why and how much. The communication between us was excellent as well. I left knowing things were going to get better. I have recently had 2 Syncope episodes, 3 weeks apart.
What could have been done to improve your experience?
Nothing! The BJC Facility is also excellent, private, quiet, secure, and expanding. Just what I hoped for when I affiliated.
