Practice Administrator

Michael began his career in medical imaging by earning his AAS in Radiologic Technology from Hudson Valley Community College. After working as a radiologic technologist for several years, Mr. Whalen made the transition into management when he assumed the position of Administrative Director of Medical Imaging at St. Mary’s Hospital, Troy, NY, in 1983. Michael became Administrative Director of Medical Imaging at St. Peter’s Hospital, Albany, NY, in 1989. During his tenure at St. Peter’s Hospital, the Department of Medical Imaging enjoyed tremendous annual growth, both in the number and variety of services performed. Our companion practice, Albany Advanced Imaging, has experienced a similar rate of growth since Mr. Whalen’s arrival in 2001. We have benefitted greatly from Mike Whalen's experience, wise counsel, and hard work during the formation of Clifton Park Advanced Imaging.

In addition to his training as a radiologic technologist, Mr. Whalen has obtained a Bachelor of Science degree from the College of St. Rose. He went on to obtain his MBA, also from St. Rose.

Michael is very active in community affairs. He is on the Boards of Directors of Sunnyside Center (a not-for-profit children’s daycare center in Troy, NY), the Latham Lassies Softball girls’ athletic league, and The Edison Club in Rexford, NY. Michael enjoys golf, and serves as a girls’ softball coach. He lives in Watervliet with his wife and two children.
