In Memoriam

Susan L. Montauk, MD played an integral role in the opening and development of The Affinity Center for 15 years.  She was the first physician on staff at the Center and began work as the Center was opened in 1996.  She previously served as the Medical Director for the Center, from 1996-2010.  She was a professor of Family Medicine at the University of Cincinnati College of Medicine and worked tirelessly as a staff physician on Cincinnati’s Health Care for the Homeless van.  The importance of her role over the years was immeasureable.  Until her death in April 2011, she continued to be a invaluable friend and consultant to the staff at the Center.

Kate Kelly Co-authored with friend Peggy Ramundo, the first book by and for people with ADD: “You Mean I’m Not Lazy, Stupid, or Crazy.” Published in 1993, it was instrumental in facilitating understanding for and reducing the stigma of ADD for the tens of thousands of people who have read it. In the early years of the Center, Kate worked in helping to develop clinical programming. Her book was an inspiration to us in creating The Affinity Center. Kate died in September 2012 after an eight month battle with bladder cancer.
