In 2367, Starfleet counselor Daniel Radke helped Benjamin Sisko and his son Jake off their escape pod from the USS Saratoga and into quarters aboard the USS Worsaae after the Battle of Wolf 359. Radke also acted as their counselor on the journey to, and once on, Earth. (Star Trek: The Prospect Chronicles: "The Burnt Child")
He and his son were Radke's patients when Radke served at Starfleet Medical in Chicago in the same year. (Star Trek: The Cantabrian Expeditions: "Dream a Little Dream of Me") It remains unclear whether Sisko visited Chicago or Radke made house calls.
