She is certified in ACLS and Fundamentals of Critical Care Management. She holds a place in the Sigma Theta Tau and Phi Kappa Phi Honor Societies.

She spent five years after receiving her nurse practitioner certification in a busy internal medicine office where she became experienced in all aspects of outpatient and medical management. Karen joined the Phoenix Heart Center and Richard Heuser, M.D., interventional cardiologist in 2001, to return to her special interest in cardiology. Together they have provided a very successful and busy downtown cardiology practice. She is very active in research and has co-authored several articles for numerous cardiology journals and publications.
