Dr. Kosinski is wonderful. Seems genuinely interested in our conversation, takes his time, answers questions. The people at the desk and the woman who scheduled my next appointment were great. The nurse who brought me from the waiting room, weighed me, etc--she was okay. Noticeably less friendly than everyone else.

I was referred to Dr. Kosinski because my LDL cholesterol level Is too high and I can't tolerate statins. He spent considerable time inquiring about my background, diet, genetic profile, lifestyle, etc. He's now got me on a plan of action that includes follow-ups with him at certain check points to make sure it's going as well as he expects and that there are no "side effects". He Is knowledgeable and considerate, and has given me the confidence I need to get my LDL level down.

The cardiologist was excellent. He gave me a good understanding of what was going on that related to my MVP following an in-hospital TEE. At the same time, he had a reassuring manner and was personable. He is a health care provider I plan to follow up with a year from now as recommended. Overall, my experience with this cardiologist was very positive!
