    Very good is too lackluster of a rating and doesn't adequately describe the care that I feel that I receive in this Clinic. I have always received outstanding care by Dr Klein. Dr Klein is a brilliant and extremely compassionate physician. He and his Team have always been responsive to any/all of my health questions / concerns. I am extraordinarily fortunate and so very grateful to have Dr.Klein as my cardiologist.
