Dr. Anthony Yoon became my cardiologist a few years ago when I was admitted to Rockwall Presbyterian Hospital with congestive heart failure(due to virus). I’ve had many doctors over the last 20+ years(crohn’s) and he’s one of my two favorites! Explains things well, kind and treats you with much respect. The staff has been very nice– in the small amount of time spent around them… However— there is one stand out… I believe his name is Ray and he’s the one that performed the Echocardiogram. The Echo can be nerve racking for a lot of people but he was so very nice and respectful(after all your ‘chest’ is being probed so you’re hanging out a bit). He noticed my nervousness and quickly put me at ease. Explained things and pointed things out on the monitor for me. Soooo nice! He is very much appreciated! And a wonderful part of a great staff.
