Our Local Office   
While the ‘Stifel’ (pronounced Stee-full) name might be new to many in Siouxland, our local office dates itself back to 1952.  It was originally founded as the Sioux City office of T.C. Henderson (an investment firm headquartered in Des Moines, Iowa).  The first office was located in the Badgerow Building.  Carl Sauer was the first manager followed by Jack Koerner and Bob O'Neill.  In 1970, the office was purchased by Piper Jaffray, a Minneapolis based brokerage firm.  The first manager under Piper was John Kelly, who managed the office from 1970 to 1992. John is the father of Cynthia Agnes, one of our advisors. Long time advisor Pat Corey is our Branch Manager.  Stifel purchased our office in October 2009.
Our office is located on the corner of Fourth and Jackson in downtown Sioux City.  The office is on first floor of the “Stifel Nicolaus” building which sits east of the Badgerow Building, north of the Main Post Office and south of the The Sioux City Hotel. 
Parking is available on both sides of Jackson and Fourth Street.  You may also park in either ramp located between Jackson and Jones Street.  We will reimburse you for your parking costs if you park in one of the conveniently located ramps.
