Affiliated in Urology was founded in 1967 by Dr. John Stutzman, who continued in the practice until his retirement in 1990. Dr. Werner Fransen, who remained in the practice until his untimely death in 2001, joined him in the 1970s. The current practicing physicians include Dr. Thomas Kulb, Dr. Vicken Chalian and Dr. Ben Leak. Dr. Kulb joined the group in 1986, Dr. Chalian in 1995, and Dr. Leak in 2003.
Generations of patients from McLean, Livingston, DeWitt, Logan, Woodford, and Tazwell counties and the surrounding areas have relied on Affiliated in Urology for their urologic care. Drs. Kulb, Chalian and Leak strive to continue that tradition of excellence in urologic care that has been established in their practice over the past forty years by offering the most up-to-date urologic procedures and services to their patients.
