Scientific Investigation & Instruction Institute


Si3 20 Years and Counting


Over the years, we have made the occasional relocation, each time to facilities that better service our clientele. Since 2011, we have been located on the ground floor of the Echelon Two Building, Suite 120, 9430 Research Blvd.  *Please be advised: The main entrance to the building faces the 5 story parking garage.

Our office is conveniently located on Highway 183 between Highway 360 (Capital of Texas Hwy) and Loop 1. We are close to downtown Austin (8 miles), I-35 (5 miles).  Hotels, restaurants, shopping are all right in our backyard. Our large, airy suite can accommodate large and small groups comfortably to provide a great learning experience for both initial (long) courses and refreshers.[/one_half]
