Practice Administrator

Kathleen (Katie) Van Buren joined North Suffolk Cardiology in 1990. She provides hands-on management of the daily operations of all of our locations while also overseeing the practice's strategic development and long-term goals. As a Fellow with the American College of Medical Practice Executives (ACMPE), one of Katie's priorities as our practice administrator is to use her extensive training, education and experience to continually deliver efficient and effective service to all our patients. It was Katie, who in 2008, successfully transitioned our office from paper charts to a fully integrated electronic medical record system (EMR), which enables all the medical professionals treating our patients to have the same patient information at their fingertips, resulting in a higher quality of care.


Our nurse practitioners are board-certified and licensed to practice medicine. They assist our physicians in diagnosing and treating patients, ordering and reviewing diagnostic tests, and writing prescriptions.
