After being raised in Washington State and trained at the University of Washington, University of Chicago and University of Oregon Dr. Rhyneer began his private practice in cardiology in Anchorage in 1971.
Dr. Rhyneer and his partner developed the first cardiology services in Alaska. The first efforts brought cardiac catheterization diagnostic services to Providence Hospital, closely followed by the addition of cardiac surgery, specialized diagnostic testing with echocardiography and nuclear imaging and the introduction of interventional procedures such as coronary angioplasty, coronary stent placement, pacemaker implantation and the development of a modern coronary care unit. He and his associates founded the Alaska Heart Institute which recruited additional cardiologists to Alaska and introduced cardiac CT scanning, cardiac MRI and the specialized treatment of cardiac rhythm disturbances using electrophysiologic testing and treatment.
Along with the care of cardiac patients Dr. Rhyneer participated in the physician management of various departments at Providence Hospital and Alaska Regional Hospital. He has been a member of the Alaska State Medical Board, Alaska State Medical Society, Opera Board, Anchorage Symphony Board, and is a founding member of Alaska Physicians and Surgeons and the Alaska Medicare Clinic. He is a fellow in the American College of Cardiology and continues to provide cardiology consultation to Alaska Regional Hospital, South Peninsula Hospital in Homer and the Alaska Native Medical Center.
